[. A Contribution to the Classification of the Coleopterous family Endomychidae. By Giipertr J. Arrow, F.Z.S.
[Read November 5th, 1919.] Pirate I,
Tue British Museum collection of this beautiful group of fungus-feeding beetles 1s a peculiarly rich one, and contains a very large proportion of all the known species, now about 750 in number. The Gorham collection, bought in 1891, contained, in addition to Mr. Gorham’s own types, many of those of Gerstaecker and Guérin, whilst many more Gorham types were afterwards acquired with the im portant Godman- Salvin and Fry collections. In amalgamating these valuable collections very numerous errors contained in the recent catalogue of Cziki (for a large proportion of which Mr. Gorham: is responsible) have come under my notice, and in putting on record the notes thus accumulated I have taken the opportunity of describing some of the more interesting of the hitherto unknown genera and species contained in the National Collection, a large part of these due to the successful collecting of Mr. Gilbert Bryant and the late W. Doherty. To the former I am indebted for the accompanying plate drawn by Miss O. F, Tassart. It is probable, from their generally conspicuous and fre-_ quently remarkable coloration, that the group as a whole is TRANS. ENT. SOC. LOND. 1920.—Parrs Tea Tse | (SANS ees

unpalatable in a high degree, like the nearest related family, the Cloccinellidae, and that an offensive fluid is exuded by many, as is the case with the largest species, Humorphus marginatus, which Mr. Bryant informs me is remarkable for its extraordinarily strong and offensive odour. I sus- pect it will be found that the characteristic grooves upon the pronotum are the channels into which this secretion 1s discharged (as Dr. G. A. K. Marshall has found to be the case in the Histeridae), and that the basal foveae when fully developed conceal the orifices of the secretory glands. These depressions, which form one of the best-marked and most constant features of the group, are more or less funnel- shaped and are always deepest just within the basal margin. At the deepest part the appearance of a pore is sometimes visible under the microscope.
Dr. C. J. Gahan, in his account of the stridulating organs of the Coleoptera, has indicated an important group charac- ter of this family in the presence or absence of a stridulatory apparatus between the head and pronotum (Trans. Ent. Soc. Lond., 1900, p. 436). He has mentioned that the exist- ence of the organ distinguishes the Eumorphites, Coryno- malites and Lycoperdinites of Chapuis, but various genera of the 3rd division must be excluded from this statement, such as Dapsa, Phalantha, Saula, and Danae. This 3rd division, however, is quite an unnatural one, and a more satisfactory arrangement is obtained by adopting Gerstaec- ker’s three Tribes, Kumorphini, Dapsini and Endomychini, and treating the presence of the stridulating organ as the primary distinctive character of the first, instead of the shape of the antennal club, which is a very inconstant and unreliable. feature. Indalmus, Ancylopus, Lycoperdina, Hylaia (Ceramis), Acinaces, and Mycetina, as well as Phaeomychus and other genera of recent date, will then jom the Eumorphini. In the more typical genera of that group, with which Indalmus and Ancylopus should be associated, the 3rd joint of the antenna 1s much longer than those immediately preceding and succeeding it, whilst in the remainder this great disproportion vanishes. The relative lenoth of these jomts is much more reliable than that of the club-joints and serves for the further division of the Eumorphini.
In the ordinary position of the head the microscopically fine stridulatory file, in the genera possessing it, lies beneath the margin of the pronotum and is not visible,

but its presence is invariably indicated by a small mem- branous lobe placed at the middle of that margin and connected with the scraping edge beneath.
T have followed in the main the order of genera adopted in the most important work upon the family, the admirable monograph by Gerstaecker. The reversed order of Cziki’s catalogue has no discoverable advantage.
Four genera introduced into this family by Blackburn may be eliminated altogether, two of them belonging to long- established genera of other families s, and the mother: although correctly referred to the Endomychidae, being redundant. Of the two former, Dyscerasphorus laticeps Blackb., is the cosmopolitan Colwocera maderae Woll., and Eleothreptus punctulatus Blackb., is a species (the second now known irom Australia) of the genus Aphanocephalus. Cranterophorus clavicorms Blackb., is an Hncymon exceed- ingly near the common EF. immaculatus, but with red femora. Finally Idiophyes is a synonym of the genus Hxysma.
It may be noted here that the Cey lonese “ Li ycoperdina ”’ glabrata, of Walker, is a species of the Heteromerous genus Levochrodes.
Genera HApLoscELIs AND HyBoPrTeEeRUs.
The name Cymones is used in Cziki’s catalogue for five Madagascar species which do not include C. sharpi Gorh., the insect to which alone the characters assigned to Cymones apply and which is a synonym of Hybopterus plagiicollis Fairm. Cymones is therefore a superfluous name and the five species should be referred to Haploscelis, a genus of strangely protean form, distinguished by the prosternum being - rather wide between the coxae but not produced be- yond: them. Haploscelis heloproides Gorh.,seems to have been based upon two specimens of different species, the female probably belonging to H. scutatus Fairm. Fairmaire says of the latter “fémurs antérieurs Inermes,” evidently meaning the tibiae. These are armed as usual in the male.
There is a peculiar feature in the male of Hybopterus which has not been noticed, viz. a delicate hooked filament at the extremity of the hind tibia on the inner side. This is evidently the homologue of the tuft of hairs found in the
same position in Haploscelis atratus Klug, and other species, and indeed may be composed of long “hairs in very close contact.
4 Mr. Gilbert J. Arrow’s Contribution to the
Genus TRYCHERUS.
Since Gerstaecker’s excellent monograph of the Endo- mychidae, in which five species of T'rycherus were described, the various additions made have been so inadequately characterised as to introduce ever-increasing confusion which nothing but the comparison of the types can now resolve. The British Museum happily possesses most of these by its acquisition of Mr. Gorham’s Kndomychidae and those of the ereat Fry bequest, the former containing types of four of the five species of Gerstaecker and a co-type of T. longanimis Thoms. 1 have therefore been in the fortunate position of having under my eyes the types of all the species of the genus hitherto described, except T. bifasciatus Gerst., raffrayi Gorh., josephus Duv., elegans Cziki, and recticollis Har. The last species I do not know ; elegans Cziki, as already noted by Fairmaire, appears to agree in all respects with longanimis Thoms., and the other three species I have determined from the deseriptions.
There is an excessive external similarity between many of the species of the genus, and the most important distinctive features are the secondary sexual characters. The im- portance of these was emphasised by Gerstaecker, but all subsequent describers have persistently neglected them.
The distribution of the genus is very interesting. The Catalogue of Cziki, published in 1910, enumerates thirteen species (excluding an Oriental form which certainly belongs elsewhere), all but one (7’. raffrayi) described from W. Africa. That species also occurs in Angola, as shown by a specimen in the British Museum. One other species (7'. fryanus) occurs in BK. Africa (Rhodesia and Zanzibar), and it is remarkable that that also was described from Angola. Since the allied eenera are those of Madagascar and the Malayan region this marked preference for the western side of Africa is striking. Of the thirteen species four have been recently received from Uganda, and no less than seven others are here described from the same region. These may be expected to occur also in W. Africa. Thus, although the species existing are evidently numerous and by no means narrowly localised, the genus seems to have no truly KE. African species. The eastern specimens of 7’. fryanus and 7’. raffrayi must be supposed to have strageled there in comparatively recent times. It is certainly curious that in spite of a bold effort to extend eastward, resulting in their
Classification of the Coleoplerous family Endomychidae. 5
reaching Uganda in such force, the genus should have found there an almost absolute barrier to its further advance. It is also a striking illustration of the fact, confirmed by all mv study of Uganda Coleoptera, that the beetle-fauna of that region is almost entirely West African and shows remarkably little connection with that of any other part of Eastern Africa.

This large species has a deceptive resemblance to 7, josephus Duv., which is found in the same localities and of which the pattern is almost the same, although in the new form the recurrent ends of the yellow elytral loop do not always coalesce with the orange apical patch. The best-marked difference is found in the absence of the basal stria of the pronotum, but the elytra are more narrowly margined, parallel-sided and convex, and the antennae in both sexes are broadly truncate at the end, whereas in T. josephus they are a little narrowed. The emargination of the front and middle tibiae and the strong spine of the middle tibia, in the male, as well as the median eroove upon the last ventral seement of the female are features not found in 7. josephus and the two tubercles at the posterior margin of the penultimate ventral segment are less widely separated than in that species. In a specimen from S. Nigeria which I regard as the male of 7. angolensis Gorh., these tubercles are three in number,

The species has a very close affinity to 7. angolensis and 7. rex, but, in addition to the absence of the reddish apical patch upon the elytra, the male is without tubercles at the hinder margin of the penultimate ventral segment and the female has. no longitudinal groove upon the terminal segment, The elytra are rather more rounded at the

shoulders than in the other two species and their apices are not produced as in 7’. rex. The club of the antenna is triangular in shape, as in the latter, but much less dilated in the male, and the excision of the front and middle tibiae in the same sex is also different.

It is rather short in form, with the elytra broadly oval and very convex, without prominent shoulders, their apices entirely reddish and a rather narrow zigzag yellow bar crossing each just before the middle. The pronotum is without a basal stria.
The front and middle tibiae of the male are excised before the extremity, the latter more deeply than the former, and the emargination is succeeded by a minute tooth, and in the middle tibia preceded by a strong tooth.
In the female the extremity of the last ventral segment is narrowly notched to a depth of about a quarter of the leneth.

This species entirely resembles 7’. ovatus, but the extremi- ties of the elytra are dark instead of pale and contain a small bilobed reddish spot. The club of the antenna is very narrow and not perceptibly broader in the male than in the female, and the latter has a notch at the apex of the abdo- men extending to about the middle of the last segment.

I have seen only two female specimens.
It is a shining black species, with a transverse pale > well zlgzae bar crossing each elytron before the middle, and the abdomen, tarsi and last joint of the antennae reddish. It is easily recognisable by its broadly oval and convex elytra,., much wider an the pronctum, with prominent shoulders and wide reflexed external margins, which are widest just behind the shoulders. The pronotum is broadest at the base, where the angles are shghtly produced. Its lateral margins are narrow and the base has a fine and rather in- conspicuous marginal stria.
This is the only known species of the:genus in which the pattern consists of a single transverse bar only.

This has the closest resemblance to 7. longanimis and appendiculatus, the pale markings being almost identical, except that the antemedian bar is less distinctly produced forwards externally. As in 7’. longanimis, the sides of the pronotum are red. The pronotum is relatively small, with its sides parallel, the front angles sharp and the hind angles right angles, and the base strongly margined. The elytra are not very convex nor very shining, “the shoulders are prominent and the lateral margins a little wider than in T. appendiculatus. The male has a rather broad club to the antenna, the first ventral segment has a small but sharp tubercle at the middle of its hind margin and the fourth is impressed in the middle and bears two rather widely separated tubercles at the hinder edge.

The species is a rather smal] one, closely resembling T. erotyloides Gerst., but smaller, with less ovate and convex elytra. The prothorax, the last joint of the antenna and the tarsi are bright yellow, the median bar and apices of the elytra paler, and the apical patch distinctly bilobed anteriorly.
The male has the middle tibiae slightly incurved at the ends and the last ventral segment rounded behind. In the female the tibiae are nearly straight, the last ventral see- ment is elongate and rather deeply grooved, and the one preceding it is broadly impressed.
The larva is flattened, with very long hairy processes fringing the body all round and with rather long antennae.

There are four specimens in the Museum.
The elytra are a little more convex and shining than those of 7. appendiculatus and T. attenuatus, which this species closely resembles in pattern, and their apices are of a uniform bright yellow colour, with the anterior edge of the patch rounded and not excised as in the species mentioned. The anterior pale mark is exactly as in 7. allenualus.
In this species the sexual difference seems to be reduced to its minimum in the genus. The usually well-marked external male characters are absent, and that sex can only be recognised, without dissection, by a very slight tooth towards the end of the front tibia at its inner edge. The thick clothing of hair at that part increases the difficulty of detecting this tooth,

This is almost identical in appearance with 7. fryanus Gorh., an Kast African species of rather wide distribution. It is a little more stronely punctured above, the shoulders are rather less rounded, and the lower surface, with the epipleurae of the elytra, paler in colour. The male is easily distinguished by the absence of the three pale mem- branous areas at the hind mareins of the 2nd, 3rd and 4th ventral segments, and by the very strong spine at the inner edge of the middle tibia.

great breadth of the mesoste nu distinguish it from them all. The prosternum is mode1 rately wide and a little pro- duced behind, where it is very slightly dilated and forms a rounded knob, bearing two small tubercles where it meets the narrowed anterior part of the mesosternum. The latter is very short and broad and the metasternum is mareined in front by a deep groove.
I have found no secondary sexual characters in the three specimens known to me. These specimens belong to two species, and one is a badly damaged individual a Cuérin’s collection, whose name (perolteti) | have adopted. This name oceurs at the end of the table of genera on p. 581 of the Rey. et Mae. de Zool., in association with that of (Hucteanus) hardwickit Hope, although the species bears neither resemblance nor relationship to that insect. In describing Amphisternus verrucosus and rudepunctatus, Gorham has remarked that those suse: belong to a section of Amphisternus “ which I believe forms the genus Haplo- morphus Guérin.” That name was clearly intended for a large part of the genus Humorphus as at present constituted, and Gorham’s remark is meaningless. I have not seen the former species, but rudepunctatus may be regarded as a rather aberrant member of the new genus Brachytrycherus. It is possible that instead of Haplomorphus Gorham intended to write Homalosternus, the genus to which Guérin tenta- tively and quite erroneously referred his (undescribed) specimen of B. perotteti, which was formerly in Gorham’s collection with that name in Guérin’s handwriting.

A single specimen received from the late M. Antoine Grouvelle, has been presented by Mr. H. EK. Andrewes to the British Museum.
This species closely resembles Bb. perotteti, but is less smooth and shining, on account of the strong and rather close puncturation of the upper surface. The pronotum 1s less convex in the middle, the longitudinal groove upon its posterior part is inconspicuous, and the hind angles are scarcely produced or acute. ‘The elytra have a very faint coppery tinge and the red markings are narrow and zig- zageed, the anterior one produced forwards close to the suture as a loop which almost touches the basal margin, the posterior one approaching but not reaching the inner and outer mareis..
Genus AMPHISTERNUS.
Gorham mentions nothing by which his Amphisternus papulatus can be distinguished from A. bellicosus Gerst., also from Sumatra, Sich he appears to have overlooked. I beheve this to be a wide-ranging species with many local races.

This 1s an entirely peculiar s species, resembling Hucteanus marseuli more than any known Amphisternus, of which genus it is nevertheless only a curiously modified repre- sentative. The antennae are very slender, with a very broad and flat club, of which the first jomt is almost an equilateral triangle and the other two conjointly about as broad as long. The pronotum is as usual rather small, with very prominent but blunt front angles. The elytra are almost parallel-sided and not long, with a trans- versely oval pale yellow patch behind the shoulders , forming an abrupt rounded swelling, and another similar one before the apex. The legs are slender, the tibiae clothed with short golden hairs, and the front tibiae of the male regularly curved in the anterior half.

The British Museum contains two specimens of each sex, all of them found in different localities.
The species is nearly allied to #. klugi Gerst., and is found in the same localities. It is smaller, shorter and more convex. ‘The pronotum is more transverse, broader before the middle, with more prominent front angles, and
the elytra are more cordiform, 2. e. they are shorter, rela- tively broader before the middle and more rapidly narrowed behind. The coloration is similar but the four elytral spots are almost exactly round in outline and of equal size.
The male has an acute spine on each of the four anterior tibiae, all equally developed, whereas in H. klugi that of the fore- leg is much stronger than that of the middle one. The apex ‘of the abdomen is hollowed beneath and not broadly emarginate as in H, kluge.
Genus HUMORPHUS.
All the known species of this genus, except H. wsignis and opalinus of Gorham and #. quadripustulatus Friv., are represented in the Museum. It is essentially Malayan, the limits of its range being apparently Celebes and Assam, and the occurrence of #. pilchri ipes in Ceylon is a remarkable fact not at present to be explained. Many more Malayan forms might be described.
With the single exception of #. bipunctatus Perty, every known species ‘of this large genus is decorated with four yellow spots upon the elytra.
The type of Pedanus laevis Gorh., is a small specimen of the very common HV, 4-gultatus Ihe.
HE. 4-verrucosus Guér., according to the type in the British Museum, is #. coloralus Gerst., and not EL. carinatus as stated in Cziki’s recent catalogue.

EL. assamensis Gerst., appears to be a variety of HL. sub- guttatus with larger spots.
E.. sanguinipes Guér. The original type of this, now in the British Museum, was re-described in error by Gorham, who supposed it to have come from Java, a mis-reading
of “ Tan ” in Hope’s Ww riting on the label, which is actually an abbreviation of “'Tanasserim.” The specimens from

Burma which Gorham attributed to H. murrayi no doubt belong to B. sangwinipes. His type of the former is a more slenderly- built insect, with clavate femora and distinctly curved hind tibiae in the male. There is no reason to doubt its Philippine origin. Another form described by Gorham with an unknown habitat, 2. expatriatus, 18 also from the Philippine Is., and is merely the female of £. thomsoni Guér., a much less smooth and shining ae than £. cyanescens Gerst., of which it stands as a synonym in Cziki’s catalogue, while E. thomsont Gorh., although de- scribed from the same specimen, is treated as a different species.

There is a tubercle at the base of each elytron near the scutellum, in place of the carina which in H#. cyanescens runs parallel to the suture for about a quarter of the length of the latter. The posterior angles of the pronotum are also a little more produced and curved. — .

The yellow dorsal patches are very large, as in FE. felix, the anterior and posterior ones separated by an interval less than the diameter of either, and also less than the interval separating the former from the basal margin. The front tibia of the male has a carina upon its outer edge, as in FE. fryanus (but rather less angulated than in that species), and the internal tooth is very strong and arises in the middle. The curvature of the middle and hind tibiae in the same sex is regular and not abrupt. The posterior angles of the prothorax are acute in both sexes and very long in the male, and the extremities of the elytra are produced in the female.

This is another species closely related to, and inter- mediate between, E. fryanus and EH. macrospilotus. It is of the same size as the former, and has the margins of the elytra similarly dilated in the corresponding sex. The elytra are a little shorter relatively, with their margins not wider at the tips than at the sides. The yellow spots are a little larger than those of ZH. fryanus, and larger abso- lutely than those of H. macrospilotus, but the latter being a rather smaller insect, the intervals between them are ereater. The anterior spots are also placed nearer the base than in the latter insect. The hind angles of the prothorax and the tibiae of the male are as in £. fryanus, but the last dorsal segment in that sex is less conspicuously bifid at the extremity.

In the male the tibiae are stouter and their inner edge (in the front tibiae as well as the rest) is closely fringed with rather long hairs. The Spine upon the front tibia is stout, clothed with hair, placed nearer the extremity than in #. lurritus, and followed by a deep abrupt excision.
Two males and three females were taken by Doherty.

Six specimens were contained, like those of the three preceding species, in the Fry Collection.
E. fraternus closely resembles E. helaeus, but the elytral margin is a little narrower at the side and a little wider at the apex, with the extreme angles acutely produced and convergent. The front tibia of the male is a little less pubescent at the inner edge and the apical excision

rather less narrow and deep. There is also a close affinity with HL. politus Gerst., but H. fraternus is a larger species with wider margins to the elytra, of which the apical angles are very sharp and convergent. The hind angles of the prothorax are less produced in the male, the front tibiae are not deeply grooved externally, as In that species, and the last ventral segment. is not acutely notched in the middle. .
Genus STICTOMELA.
This genus seems to be peculiar to Ceylon and its species have hitherto been found only by Mr. George Lewis. A third representative is “ Spathomeles”’ inflatus Gorh., which has the characteristic heavy build, narrow loosely- jointed antennal club and tumid shoulders of the other two.
Genus AMPHIX.
The types of Bates’ monograph of this genus are in the British Museum. A. gerstaeckert is not, as supposed by Cziki, a form of A. vestitus Panz., nor are circumcinctus and robustus of Bates varieties of A. discordeus F,
Genus InDALMUS.
The distribution of species between the two genera Ancylopus and Indalmus is quite unnatural. It seems to have been decided entirely by the appearance presented by the front coxae, which are said to be contiguous in Ancylopus and separated in Indalmus. In reality there is always a thin lamina between the coxae and this differs to a shght extent in its breadth, but the variation is so small that, in the absence of any other and sharper dis- tinctive character there seems no reason to make an arbitrary break in the series of stages which connect the two extremes. The mesosternum exhibits a variety of forms which are much more marked than those of the prosternum, but have no relation at all to the present erouping of the species. The typical species of Ancylopus (A. melanocephalus Oliv., of which A. bisignatus Gerst., is probably a colour-variety) quite obviously stands apart from the rest, which cannot at present be easily separated, although it may perhaps be found desirable in the future to devise additional genera. I therefore transfer to
29, Mr. Gilbert J. Arrow’s Contribution to the
Indalmus the other forms at present placed in Ancylopus. A. melanocephalus has in the female a very remarkable transverse sulcus upon the pronotum and an oblique im- pression upon each elytron of which no trace is found in any other described species. In the male a small but important distinctive character which seems not to have been noticed exists in the antennae, the eighth joint of which is narrower than either of those adjoining it.
Indalmus bivittatus Perch. (or the species to which it is agreed to apply that name) appears to inhabit a very large part of Africa, It is very variable in coloration and fae been many times described, the names wnicolor Gerst., fuscrpennis Gahan, and nigrofuscus Gorh., being synonyms of it.
Fairmaire has described (Ann. Soc. Ent. Belg. 1897, p. 203) as Indalmus biviltatus a species from Madagascar which is evidently distmet and which is omitted from the Catalogue. To avoid confusion this may be re-named

The Museum Collection contains a pair from each of the localities above named.
It is an interesting form, intermediate between Indalmus and Lycoperdina, different as the typical forms of those genera are. In outline it is transitional between the oblong shape of the former and the short tapering Lycoper- dina type. The pronotum is strongly transverse but distinctly narrows behind. The antennal club is two- jointed, the last two joints being connate and_ slightly

transverse and the 9th joint not distinctly larger than the 8th. The 2nd joint is slightly elongate, the 4th a little shorter than the 2nd (as in Lycoperdina) and the 3rd about twice as long as the 4th.
In size, colour and general appearance there is a strong
resemblance to Lycoperdina sericea, but the colour is generally more uniformly reddish (im one specimen the median dorsal part is nearly black). The tarsi and the club of the antenna alone are pale. The pronotum is shorter and the elytra are longer than in Lycoperdina, and the latter are rather parallel- -sided, not perceptibly dilating behind the shoulders. The entire upper surface is closely and rather strongly punctured and clothed with decumbent erey hairs. _ The curved hind tibia of the male bears a minute spine just before the extremity, and the hind femur in that sex is provided with a comb-hke series of still more minute teeth unlike anything else known in the family.
Genus DryapIvTes.
Myceltina erubescens Gorh., is a species of Dryadites, a genus very different from Mycelina. There is nothing in the description by which the insect can be distinguished from D. borneensis Friv.
The following species also belong to the genus.

The club of the antenna is much smaller, its first and last joints being much narrower than the middle one, the first triangular and the other two very short and closely articulated.

Only a single specimen was found.
The elytra are of a deep purple colour, and each has a deep blood-red patch behind the middle. The pronotum is relatively narrower than in D. borneensis and D, latipennis, its sides are not hollowed as in those species nor its lateral margins evenly rounded, and the front angles are blunter, The antennae are rather shorter, the club narrow, closely articulated and parallel-sided and the third joint relatively less elongate.
Genus Mycrrtina.
Mycetina candens Gorh., is obviously synonymous with M. castanea Gerst. Although he has omitted to mention the fact, Gorham’s type is a male, of which sex Gerstaecker
carefully detailed the well-marked characteristics, making the former’s error more surprising.
There appears to be a tendency in this genus, contrary to that generally observed in beetles, for the male to be of slightly larger size than the female.
It is difficult to understand why Lycoperdina testacea Ziegl., was placed by Leconte and Gerstaecker in this senus, from which it differs widely, as its very loosely- jointed antennal club indicates. The absence of a stridu- latory flange to the pronotum excludes it from the present group, and I refer it to the genus Danae.

Hab, Assam: Patkai Hills (W. Doherty).
There are two specimens, probably females, in the British Museum.
The species shows a nearer relationship to the European and North American forms than to any other yet known from the Oriental region. It has the characteristic four spots upon the elytra, but these are of a very pale yellow colour and the whole remaining upper surface is black, slightly tinged with red upon the head and the front angles of the pronotum. It is rather broad in form, with the sides of the pronotum roughly punctured, the margins straight and parallel behind, the elytra rather strongly punctured, their outer edges a little flattened, their apices rounded and not angulate and the antennae compact, with a well-defined, rather oblong club.

A considerable series was found by Mr. Bryant at Penang. where the species was also taken by Lamb many years ago,
“The shape is pecuhar. Excluding M. testacea, which does not belong to the genus, it is the most elongate species known to me. Its widest part is considerably “behind the middle of the elytra and the pronotum at its widest part is narrower than the elytra at the shoulders. It is very smooth and shining above, except at the sides of the pronotum, which are rugulose and thinly clothed with very minute grey setae, the entire upper surface bearing similar but scattered and extremely minute setae, and the head, legs and lower surface rather closely clothed with very short hair, The antennae are rather long but closely articulated and widening gradually from the third joint, the three joints forming the club being little differentiated from the rest.
The female is almost similar to the male, but the antennae are a little shorter and all the tibiae rather more slender.

Mr. Bryant found one specimen of each sex.
This species is very similar to M. brevcollis Gorh., and identical in coloration, except that three, instead of only two, basal joints of the antenna are red. Those organs, however, are not stout and compact, but slender and loosely- jointed, ‘with a club composed of three joints only. The sides of the prothorax are strongly rounded in front and

as the prothorax. The elytra have broad recurved lateral margins.
M. lurida is chiefly notable for its strongly-marked male features. The legs in that sex are very long’ and stout, the middle and hind femora thickened and a little curved, the antennae loosely-jomted and slender, and the fifth ventral segment bears a strongly elevated transverse crest: or carina, “produced at each end and curved inwards and backwards.

This little species is easily recognisable by its very short, globular shape and the beautiful metallic purple colour of the upper surface. The coloration is similar to that of WM. lurida, but the purple hue is much more intense, and the antennae, although coloured in the same way, with the terminal joint pale, are much shorter and more compact.

It is broadly oval in shape, with the pronotum shorter than in M. doriae and M. soror and not perceptibly contracted behind, and the elytra short ee not hemispherical as in M. cyanipenns. The antennae are rather less compact than in those species. In the male fie? antennae are less robust, the hind tibiae are distorted, and the elytra are more distinctly margined laterally.

This is a very rotund and compactly-formed species of a nearly uniform reddish-brown colour, but with the last 8 joints of the antennae black, except the extreme apex. The antennae are very broad and closely jointed, with the last three joints strongly transverse. It is rather more rotund than M. brevicollis Gorh., and almost as much so as M. globosa Arr., to which it has perhaps the closest resemblance. The puncturation is finer than in either of those, and the colour is almost uniformly brown, with no trace of metallic lustre (in the dead specimens at least). The joints of the antennae also are rather shorter and closer and the terminal one is only pale at its extremity.

The species closely resembles M. pulchella, the size, shape and coloration being the same, except that the apices of the elytra have a sharply-lmited yellow patch. The male has the legs quite simple but stouter than those of the female. As in Mycetina pulchella, it is larger than the female, relatively a little more elongate, cae wider margins to the elytra and more dilated antennae, of which all three club- -joints, as well as the two joints preceding them, are distinctly transverse. In the female only the last two are distinctly transverse, the fifth to the ‘ninth being about as long as thev are broad.

It closely resembles M. pulchella, but the elytra are more hemi- spherical in shape and blue instead of violet in colour, with narrowly reflexed margins. The legs are moderately slender and the tibiae narrow and a little curved in the anterior half, broader towards the end. The antennae are stout and compact, gradually dilating towards the club, which is broad, with the last two joints transverse.

There is a close resemblance to Mycelina cinclipennis and M. pallida, but the elytra are only vaguely clouded instead of having the whole central part black as in the former. The pronotum is rather narrower relatively than in either of those species, especially at the shoulders, and is a little produced backwards at the base, so that the basal sulcus is a little farther from the hind margin, which has a more rounded outline. The elytra are rather shorter and more broadly rounded behind, and the antennae are shorter, broader and more compact, with the three basal joints red.

The sides of the pronotum are nearly straight and parallel behind, the margins rather thickened, the elytra gently dilating from the shoulders and their lateral margins narrowly reflexed. The antennae are stout and compact and in the male the ninth joimt is much larger than the two last joints combined. The front tibia m the same sex has a slight tooth near the base.

A single specimen of this species, taken by Prof. C. F. Baker, has been kindly presented by him to the British Museum Collection.
It is rather smaller than either of the species already described and more glossy, the elytra especially bemg much more finely punctured. The four red elytral spots are moderately large and of rather rounded form and the anterior ones do not reach the shoulders. The head and legs are deep red in the type specimen, and the pronotum is ‘bright red in front, but becomes gradually darker towards the Bane. The eyes are large and the interval between them is distinctly less than their combined diameters. The front angles of the pronotum are blunt, the lateral margins are moderately thickened but gradually diminish towards the front angles, and the basal margin is broad, The elytra are less broadly rounded at the sides than in

In the male the 9th joint of the antenna is larger than the 10th, but scarcely as large as the 11th.
Genus DANAE.
The genera Danae and Saula consist of very numerous and extremely similar minute species, which have so far received no careful study. In his monograph Gerstaecker described two species belonging to the first genus under the name of Oediarthrus, and stated that the enlargement of the 9th joint of the antenna was common to both sexes. This is a mistake which has led astray those who have followed him and has not been corrected in the recent catalogue. Weise has recognised the sexual character of the remarkable antennal structure, but has added to the
existing difficulties by giving new names to female speci-
mens. The 9th antennal joint is found in all degrees of development in the males of different species and is of normal form in the females, so that it is useless as a generic character, and the many species I have been able to bring together show that nothing remains by which it is possible to separate generically Danae, Oediarthrus, Rhabduchus and Coniopoda. All these are distinguished from Saula by the broadly margined prothorax and transversely elliptical scutellum. The genus Heliobletus, which Cziki has amalgamated with Saula, is intermediate between the latter and Danae, being (like Saula) without a wide prothoracic margin but, like Danae, having the scutellum transverse and reunideds while the antennae have also the 9th joint enlarged in the male, which has not hitherto been known.
In addition to this curious feature of the male antenna in these two genera, striking differences may also be found in the legs in ‘the same sex and these afford the best means of distinguishing the species. The females, on the other hand, are so much alike that unless they can be associated without doubt with the other sex they are best left alone.
As already mentioned, I refer to Danae the North American “ Mycetina”’ testacea Ziegl., which is not very remote from the Japanese D. orientalis Gorh. In these species external sexual differences are practically absent.
Danae rufula Reiche, venustula Gestro, abdominalis and
36 Mr. Gilbert J. Arrow’s Contribution to the
similis Weise and Heliobletus servilis Gorham, have all unfortunately been described from female types, and it may never be possible to establish with certainty the essential diagnostic characters of their species. The types of the first and last are in the British Museum.
Besides the curious differences in the antennae and legs, the males of Danae. are generally more elongated than ihe females, owing to the enlargement of the metasternum and Ist abdominal seoment and the consequent lengthening of the elytra. The hind legs are generally longer, placed. farther back and frequently toothed at the inner ‘edge of the femur or tibia.
Dr. Marshall found these insects at the roots of grass in damp places.
In a male specimen which I believe to agree with the female type in our collection of Danae rufula Reiche, the middle and hind tibiae are curved as in Danae natalensis Gerst., and the club of the antenna alone is black, but it 1s a rather larger species and more shining, the punctures upon the pronotum especially being fairly close but less coarse. The pronotum is also relatively wider, with more dilated margins. The supposed difference between Danae rufula
Reiche and D. bulbifera Weise, described by Weise (viz. the marginal sulcus not diverging to the hind angle in the former r) has no real existence but, from the size, Danae bulbifera is perhaps more likely to be Danae natalensis. Gerstaecker’s figure of the latter, upon which Weise relied, is worthless and does not correspond with the description.
No species known to me has the 9th joint of the antenna shaped quite as represented in Danae pulchella Gestro, and Danae senegalensis Gerstaecker, 1s probably also different from any species in our collection.

A single male from Nigeria appears to agree in ai respects with a male and three females from Nyasaland,
The male of this species is easily recognised by the very peculiar structure of the hind legs (see page 41, fig. 3). The tibia bears a large and very prominent tooth ‘placed a little beyond the base at the inner edge, in the form of a flattened plate, a little hollowed on its upper side, bluntly pointed and directed obliquely backwards, and the femur is curved, hollowed out behind, and has a broad rounded lobe or lamina at the middle of the upper edge of the excavation. All the tibiae are slender at the base and shehtly thickened towards the extremity.
The inflated 9th joint of the antenna is very deeply scooped out beneath just beyond the base. The upper surface is shining, the pronotum rather flat and very lightly punctured, the sides very feebly excised behind, the hind angles scarcely produced and the elevated lateral mareins not angularly narrowed behind but the inner edge very shehtly curved towards the hind anele.

This has a very close resemblance to D. femoralis in which also the antennae, femora and tibiae are black, but the
38 Mr. Gilbert J. Arrow’s Contribution to the
hind femora of the male are much more slender and not toothed and the tibia instead bears an obtuse tooth beyond the base (see page 41, fig. 5). The 9th jomt of the antenna in that sex is still more dilated, its diameter at the distal end, where it is widest, being about equal to its length. The shape of the thorax is practically the same, but it is a little more strongly punctured.

It is a rather pale species, with the antennae red and the last three joints only black. It is rather shining and very finely pubescent, but with well-marked puncturation above.
The sides of the prothorax are not at all sinuated behind and the hind angles are almost right angles. In the male the tibiae are straight, but the hind legs are elongate, the femora a little arched and the tibiae slender, with a small but sharp tooth before the middle of the inner edge, pointing backward (see page 41, fig. 2).

This differs from all other species known to me by the black colour of the legs as well as the antennae. The pronotum is rather short, with the sides nearly straight behind and the marginal groove greatly curved and Aa abruptly bent towards the hind angle. The male has the elytra elongate, the 9th joint of the antenna swollen, pear- shaped and a little hollowed beneath, the middle and hind femora and tibiae gently curved, the hind femur bearing a strong but broad tooth behind (see page 41, fig. 4) and the first. ventral segment very long and produced backwards in the middle.

Only a single specimen of this has been found. It is of very elongate form, but with a short transverse prothorax, whose sides are nearly straight behind and the hind angles nearly right angles. The “puncturation is very minute and scanty but the pubescence fairly thick. The male characters are again very distinctive. The swollen 9th joint of the antenna is very short and transversely globular and the hind legs are long, with the femur slightly arched and the tibia slender throughout, strongly curved in its posterior half and armed internally a little behind the base with a conspicuous blunt tooth (see page 41, fig. 6).

It is a rather broadly. oval species, uniformly coloured except for the last 6 or 8 jomts of the antenna, which are dark (but not black) with the extreme tip reddish. It is very convex and shining, with fine but deep and distinct punctures. The sides of the pronotum are rounded and not distinctly bisinuated, the margins rather broad and only slightly narrowed behind. The base is very deeply suleate and the borders of the sulcus both in front and behind become sharp and overhanging on each side, forming narrow-mouthed but very deep cavities, which extend into the angles formed by the base and the lateral margins of the pronotum. The elytra in both sexes are rather short, very convex and stronely rounded at the sides.

distinguished from all others by the very fine close punctur- ation of the pronotum. The elevated margin of the latter is parallel-sided and not very broad, and the hind angles are very slightly acute. The legs and antennae (except the last 3 joints of the latter) are ferrugineous in colour like the rest of the insect. Danae similis Weise (also from Natal) has the same colouring, but the joints comprising the footstalk of the antenna are described as transverse. From this and the enlarged 9th joint it appears probable that the specimen described is a male, and not a female as stated.

The type is unique. In the antennae and legs the species is quite different from any other. The former are long, entirely black and clothed with rather long and close dark hairs. The last 3 joimts are much larger than the rest, but do not greatly differ among themselves. They are all elongate, the 9th being the broadest, the 10th the shortest and the 11th the longest. The legs are slender, the middle femur bearing a blunt tooth beneath, the hind femur curved and slightly clubbed and the hind tibia closely fringed with rather lone and stiff yellow hairs (see page ‘41, fig. 8). The Ist “ventral segment bears a conical tubercle near the middle of the hind margin.
The upper surface is shining and very finely and lightly punctured. The pronotum is short and broad, with the elevated lateral margin not wide and not distinctly narrowed behind, the sides feebly sinuated behind and the hind angles acute.
Genus HELIOBLETUS.
On the strength of an injudicious remark by Gorham, Cziki has sunk this genus as asynonym of Saula, and treated its Bornean type, H. servilis Gorh., as identical with the Ceylonese S. ferruginea Gerst. The two faunas are entirely distinct and the insects are generically different. Although only the unique female type of H. servilis is known, I believe the male will be found to have the 9th joint of the antenna swollen, as in Danae, whereas the sexes of Saula are practically identical externally. The antennae in the latter genus are extremely delicate, with slender, loosely- articulated joints. In Heliobletus they are thicker, with more compact and closely-articulated joints, the terminal one not very elongate and the penultimate (10th) strongly transverse. The 9th joint is generally perceptibly larger than the 10th, even in the female.

This ie is a small insect, with the upper surface strongly punctured, as in H. servilis, but more finely and closely. The sides of the pronotum are much less strongly curved than in that species or H. latipes, being very gently rounded in front and nearly straight behind, with the hind angles right angles. The antennae are like those of H. latipes, but a little more slender, with joints 2 and 3 elongate, 4 to 8 beadhke and about as long as they are wide. The legs are slender and the tibiae nearly straight, but those of the front and middle pairs a little dilated towards the extremities.

This is rather smaller and more graceful and tapering in shape than H. servilis, as well as more finely punctured.
The antennae and legs are rather stout, the 3rd to 8th jomts of the former being short and compact, the 9th large, shortly oval and slightly excavated beneath, the 1lOth small, transversely triat veular, and the 11th shortly oval. The middle and hind tibiae are dilated beyond the base, the latter about as wide as the femora (see page 41, fig. 9).

Genus APHORISTA.
A. humeralis Gorh., is synonymous with A. morosa Lec,
Genus Epreocus.
The Central American species of Hpipocus have been greatly confused by Gorham, partly owing to his having failed to correctly distinguish the sexes, and his erouping of them according to the shape of the tips of the elytra is misleading. This feature varies to a greater or less extent according to the sex. Thus, although E. bivittatus is grouped by him as a species with the apex of the elytra rounded and the male is said to differ from the female only in having a minute tooth near the apex of the front tibia, he has floured a male showing no tibial tooth (which is very distinct but at a distance from the apex), but correctly representing the extremities of the elytra as truncated and sharply pointed, The sexes can be distinguished with
Classification of the Coleopterous family Endomychidae. 45
the greatest ease in this genus by the great difference in the terminal part of the abdomen, the males having a rather long and more or less asymmetric al sixth segment, often exposing on the left side a slender chitinous ramus of the aedeagus.
The description and figure of #. sallaec Gorh., are of the male and not the female as supposed, and the dilated elytra may be a male characteristic. There is no tooth to the front tibia in this sex, but all the tibiae are curved and rather clavate.
The two specimens supposed by Gorham to be male and female of FE. subcostatus Gorh., are both males, and that described as the female of #. brunneus Gorh., may be that of L. subcostatus, but the type specimen of H. brunneus is identical with the earlier-described EH. mollicomus Gorh., the original specimens of which are very immature.
The specumens referred by him to /. rufitarsis Chevr., in- clude HL. fulaginosus Guér., and, judging by the considerable differences in the aedeagi of the males, several other species as well, but more adequate series are necessary to enable these to be satisfactorily described.

The specimen from San Joachin, Guatemala, referred to A. liquefactus by Gorham (Biol. Centr.-Amer. vii, p. 126), figures again two pages later in the same work as Anidrytus BS sp. It is very obviously different from A. liquefactus, and Gorham is quite wrong in saying that it is without an internal tooth to the front tibia, for there is a very strong one produced by the abrupt dilatation of the apical part, which is much less flattened and bent than in the other male specimen described by him. This species may be called
Anidrytus guatemalae, sp. n.
Gorham has given a description of the unique specimen, but besides the features mentioned by him it is considerably longer and narrower than A. liquefactus, more densely punctured and pubescent, scarcely shining and with much more slender legs and antennae.
Length 8 mm.; breadth 5 mm.
E'phebus depressus Gorh., has all the characters of Ani- drytus, to which it must be referred. As Gorham later used the same specific name for a Guatemalan member of this genus, the latter must be renamed and I propose to call it
Anidrytus decoratus, nom. nov.
Amdrytus fallaciosus Gorh., appears to be A. ephippium Gerst., from which, although described from the same region, Gorham did not attempt to distinguish it. The pronotum is not, as he states, more deeply punctured in the middle than at the sides. This error, ag well as the general inadequacy of the description, was no doubt due to the extremely dirty state of his specimen.
The following new species is closely related to the last. It appears to. resemble none of the Peruvian species described by Kirsch.

Its dark area is much narrower in front than behind, where it usually reaches the hind angles. Upon the elytra the dark patch ‘extends almost to the outer edges, enclosing a conspicuous humeral spot, and its posterior margin is jagged near the suture. In the male the front tibia is curved, thickened at the end, with a minute sharp eee which is absent in A. ephippium.

Two specimens (male and female) from the Fry Collection, although evidently of the same species, differ considerably i in fora The male is very short and broad, with the sides of the prothorax gently curved in front ‘and divergent behind and the hind angles acutely produced. The female is narrower, the sides of the thorax are strongly rounded in front and parallel behind, and the hind angles are right angles. The club of the antenna is longer. and the 9th and 10th joints less transverse and less angulated anteriorly. The front tibia of the male is slender and curved in its anterior half and toothed beneath a little beyond the middle.
Genus Kroprerus.
The South American Hpopterus ocellatus Oliv., must be removed from the list of Central American species. The common insect so named by Gorham, which, in spite of its different aspect, appeared to him impossible to separate satisfactorily, is not likely to cause similar difficulty to others. It is a larger, broader and less closely punctured and hairy insect, with a pattern composed of only two, instead of three, colours as in EB. ocellatus. 1 consider it to belong to HL. partitus Gerst., but with the black markings rather more reduced than in the typical form.
Genus STENOTARSUS.
Cziki has introduced a new name, Stenotarsoides, for the Asiatic species of Stenotarsus. This he describes as a genus, although without indicating a single distinctive character. While separating, according to his notions of propriety, the Asiatic species, he associates still the American and African, whether from geographical or zoological reasons is immaterial, since his so-called genus, in the absence of any diagnostic character, cannot reason- ably be held to have any substantial existence. It is true that the International Rules of Nomenclature recognise
Classification of the Coleopterous family Endomychidae. 49
the “indication ” of species as sufficient to validate a new generic name, but the fact that this would permit any cataloguer to introduce genera upon fantastic grounds which, as in the present case, may not even pretend to be morphological, seems to preclude the possibility of its ever being generally adopted.
Gerstaecker pointed out more than half a century ago that (as would be expected) the African species of Steno- tarsus are, in certain respects, more nearly related to the Oriental species than to the American, and Gorham, in describing the Japanese S. internexus, has noticed that it forms the connecting link between the New World and Old World forms. The genus is in fact a worldwide one, passing with scarcely perceptible change of form from Tropical Asia through Japan to North and Tropical America, like the Mongolian race of men, and through the Kastern Tropics to Australia and Madagascar (iS. internexus, just mentioned, has an obvious relationship to the N. American S. hispidus).
S. guineensis Gerst., ranges from Sierra Leone to Uganda, and S. aequatus Gorh., is a synonym for it. Gorham notes that his type is much less pubescent than S. guineenses. This is true, the clothing having been rubbed off so that scarcely a trace remains. S. mombonensis Weise, 1s exceedingly similar, but the raised margin of the thorax is narrower and the footstalk of the antenna only pale at the base. It is common in Nyasaland and Gazaland.
Stenotarsus ursinus and 8. leoninus have been described as unicolorous species, but examples of both occur in which the elytra are marked with black spots in the same position as in S. pantherinus Gorh., the basal one, however, more broadly adjacent to the anterior margin. In S. ursinus the spotted form seems peculiar to North Borneo, while Sarawak specimens never show more than a slight indica- tion of spots.
Gorham appears to have been wrong in attributing Central American specimens to S. claviger Gerst., the form of the antennal club in these agreeing rather with that of S. validicornis. The specimen from St. Catherina referred to by Gerstaecker as belonging to S. claviger was in Gorham’s collection (now in the British Museum), but this specimen does not agree with the description and must have been too hastily examined by Gerstaecker. I believe it to be a rather large specimen of S. minutus.

The specimen from Guatemala attributed to, and figured as, S. maculicollis Gerst., in Biol. Centr.-Amer. vol. vii, although extremely similar, must be separated from it, the antennae being considerably shorter and more compact and the club distinctly larger proportionately to the footstalk. The sides of the pronotum are more strongly curved and nearly parallel behind, and the raised margins broader. In both species the basal foveae form very deep and strongly oblique channels.
The Central American species may be called
Stenotarsus marginalis, sp. n.
S. maculicollis Gerst., really belongs to the section with elongate joints to the footstalk of the antenna.
The genus evidently forms exceedingly numerous local races in Tropical America, some of them having slight structural differences, while some, like S. tarsalis Gorh., seem to me no more than colour varieties (the latter of S. circumdatus Gerst.). Gorham has pointed out nothing to distinguish his S. cordatus from S. globosus Guér., and I have found nothing. The difference in the size of the thorax shown in his figures is quite imaginary. He evidently did not compare his specimens or he would have found the length of the legs to be distinctive of the males of S. globosus.
The specimens from Guatemala referred by him to S. orbicularis Gerst., do not agree in the least with the description of that species. They have no resemblance to S. rubicundus and are not at all orbicular. As Gorham has described the form it is sufficient to give it a name and I propose to call it
Stenotarsus ovalis, sp. n.
It is almost regularly oval in shape, with the shoulders less prominent and the elytra less convex than in S. globosus. There are two specimens, male and female, the male having the legs and antennae elongated, as in S. globosus.
The specimen from Panama is not conspecific with the last. Its pronotum is more closely punctured, the sides less strongly rounded, the front angles less prominent, and the lateral margins much narrower. It may be called
Classification of the Coleopterous family Endomychidae. 51
Stenotarsus chiriquinus, sp. n.
The sexual features mentioned above (¢. e. the elongation of the legs and antennae of the males), although recognised by Gerstaecker, were ignored by Gorham. The latter’s S. macroceras is the male of S. purpuratus Gerst. Still more remarkable than the great elongation of the antennae and legs in that form is the sharpening of the hind angles of the prothorax.
There is no valid reason for the inclusion of S. adum- bratus Gorh., in the Central American fauna, the specimen from Tactic so identified being quite different from the Colombian type with short antennae to which alone the description applies. The Guatemalan species may be called

The antennae (of the male) are slender, fully two-thirds as long as the body, with the joints elongate, except the Sth, 9th, and LOth, of which the 8th is beadlike, the 9th about as long as it is wide, and the 10th transverse, the last three joints not greatly dilated but very loosely articulated. The elytra are finely but distinctly and not closely punctured, the punctures being larger behind the shoulders.

The single specimen of this species was not distinguished by Gorham from 8. pilater, of which it has the colour and size, although otherwise entirely different. It has a very regular broadly oval outline, the pronotum being almost exactly semicircular in shape, allowing for the emargina- tion which receives the head. The raised margins are very broad and only a very little narrower behind than in front. The elytra are rather strongly, evenly and closely punctured.

This rather closely resembles S, palatei Gorh., with which it was confused by Gorham, but it is more broadly oval and less attenuated behind, and the elytra are very finely and closely punctured, ‘without large scattered punctures. The antennae have six, instead of four, joints dark and all but the second joint are elongate. The legs are longer in the male than in the female.
The two insects associated by Gorham as forming his genus Systaechea are very obviously not nearly related. The figure of the second species, S. championi, does not accurately represent the antennal club, which is compact and rather abrupt—indeed, exactly as in Anidrytus—and entirely different from that of the first species, Systaechea cyanoptera. Vf compared with Anidrytus dolosus Gorh. (from the same locality) it will at once be seen that it is really a closely-allied species of the same genus. S. cyanoptera, which must be regarded as the type of Systaechea, has no tangible character by which it can be distinguished from Stenotarsus, although a rather isolated species.

The species is easily recognisable by its entirely black and rather slender legs and antennae. The upper surface is deep red in colour, a little paler at the sides of the pro- notum, and not very densely clothed with fairly coarse ereyish pubescence, scanty upon the middle of the pro- notum, which is smooth and shining. The lateral margins of the latter are strongly elevated, but not wide, and there is a deep basal sulcus or stria close to the margin. The elytra are strongly and irregularly punctured, without distinct lines, moderately broad behind the shoulders and tapering at the apices.

Several specimens were found in January and February by Mr. G. E. Bryant.
It is a small globular species of dark chestnut colour, with the legs and antennae pale, except the 9th, 10th and the basal half of the last joint of the latter, which are dark, itis entirely clothed above with a yellowis sh pubescence, which is rather less fine than in the two following species, especially upon the elytra. The pronotum is finely, closely and evenly punctured, with wide lateral margins and without a basal stria. The elytra are rather more coarsely punctured, with an indication of alternating longitudinal bands of larger and smaller punctures at the sides. The antennae are a little stouter than in S. basalis, with the 9th joint nearly globular, the 10th rather transverse and the last elongate-oval.
S. contractus Gorh., from Burma, is evidently very lke this, but the lateral margins of the pronotum are there very narrow.

Genus CHONDRIA.
Gorham was quite wrong in describing this genus as more closely allied to Symbiotes than to Stenotarsus. The tarsi are not, as he says, quite simple, but are entirely unlike those of Symbiotes, of which the first three joints are short and of nearly equal size. In Chondria, the first is elongate, the second produced, much less than in Sleno- tarsus but beyond the third joint, which is very small and inconspicuous. Hverything else is as in Sfenotarsus, of which it is therefore only a rather simplified, perhaps degenerate, form. The production of the second joint is more apparent in the hind feet than in the anterior ones. Cziki, in Ann. Mus. Nat. Hung. in, 1905, p. 573, has actually described the second joint as long and bilobed, from which it is evident that he does not know the genus. Only a single species has been known hitherto, but several more are described here, each represented only by a single

It is rather oblong in shape and the pronotum is broad in front and parallel-sided behind, with a deep basal groove not very close to the margin, and the elevated lateral margins very broad in front but considerably narrowed behind. The elytra are finely but distinctly seriate- punctate. The antennae are slender, with the 2nd_ to the 10th joints spherical, the last three large and the terminal one elongate-oval.
Probably in the quite fresh state the body is rather more hairy than in the unique type specimen, but this latter is otherwise in perfect condition.

This is the second described species of a peculiar genus, of which the elevated sides of the pronotum, as well as the hairy surface, indicate a relationship to Stenotarsus, but the antennae are markedly different from those of all other genera of the family hitherto described. There is no transition from footstalk to club, but the latter is very abrupt, and pectinate in form, its three joints being loosely connected at their outer sides, the two basal ones strongly

transverse and the terminal one almost circular. The prosternum is moderately broad between the front coxae and produced beyond them, truncate bebind and over- lapping the front part of the mesosternum, except when the body is fully extended. The exposed part of the mesosternum is strongly transverse and the metasternum is slightly emarginate at its junction with the mesosternum, There is a rather deep depression on each side of the meta- sternum behind the middle coxae and also a circular depression on each side of the first ventral segment behind the hind coxae. This segment is as long as the remaining four together and is very strongly punctured at the sides.
The pronotum is very coarsely and deeply punctured, of the breadth of the elytra at the base and not very strongly narrowed in front. The lateral margins are moderately broad and rather declivous, with their inner edges very sharply carinate. The elytra are much more finely and closely punctured than the pronotum, and have the shoulders slightly prominent. From the Japanese species (H#. basalis Gorh.), previously described, E. monti- cola differs by its coloration, coarser puncturation and wider margins to the pronotum.

This is a very peculiar and isolated genus. It is appar- ently a wingless form and the elytra, although long, are separately rounded at the end and leave exposed the extremity of the abdomen. The whole surface of the body, including the legs, is covered with fine silky hair.
64 Mr. Gilbert J. Arrow’s Contribution to the
The antennae are much shorter than usual in the Endo- mychidae, with the three-jointed club not much dilated, but the last joint strongly asymmetrical and pointed. The hind legs are stouter than the rest and all the tarsi are rather long, but the second joint is strongly lobed. The general appearance rather suggests that “of Litho- philus, although the antennae are longer, the tarsi more lobed and the penultimate (third) joint more conspicuous. The pronotum has very broad raised margins, as in Stenotarsus.

Two specimens without apparent sexual difference.
Although much larger than the typical species, P. russulus, ‘and differing from it considerably in shape, this species has all the peculiar structural features of the genus. It is a much shorter and more convex insect, very shining but with well-marked punctures upon the elytra, forming rather broad irregular longitudinal lines.
The sides of the pronotum are more broadly concave than in P. russulus, the elevated lateral margins a little narrower in proportion and the sides more gently and uniformly curved. The elytra are relatively very short, with the shoulders very prominent and the curvature of the sides continuous with that of the sides of the pro- thorax. They are also much more convex and more pointed behind than those of P. russulus. The antennae are long and slender, with a loosely jointed club. Although a broader insect the prosternum is rather narrower than in P. russulus. The latter species was taken at Hobart by J. J. Walker,

66 Mr. Gilbert J. Arrow’s Contribution to the
Genus ENDOMYCHUS
As Gorham has himself admitted (Proc. Zool. Soc., 1887, p. 650), the difference in the maxillary palpi upon which he based the genus Cyanauges (Coenomychus Lewis) is not a substantial one and that genus is insufficiently distinguished from Hndomychus. He has rightly referred here Mycetina limbata Horn (which Cziki’s catalogue has for no apparent reason placed in Aphorista), but is entirely wrong in uniting with it the insect he himself very cursorily described (Endomycici Recitati, 1873, p. 64) as Hndomychus 4-punctatus. That species, omitted from the catalogue, is very like #. coccineus L., but of shorter form. The actual habitat of the species, the unique specimen of which is now in the British Museum, is uncertain.
Genus KuUCTEANUS.
The British Museum is fortunate in possessing types of all the known species of this genus. The remarkable uniformity which exists in the colour and pattern has caused the number of species to be overlooked. Not only have #. hardwickei Hope and EL. coelestinus Gerst., been wrongly united, but the specimens described by Gorham as Li. cruciger and EH. doherty: consist in each case of two species. As Mr. Gorham has not confined himself to the selection of a single type of the species described by him, I have selected in these cases the specimens from which the figures accompanying his descriptions have been drawn. ££. hardwickei Hope differs from FL. coeles- tinus Gerst. (the type of which has been acquired with the Gorham collection) by its longer antennae, narrower club, more transverse pronotum and the markedly oblique position of the anterior elytral patches.
The genus consists of two very well-marked divisions, the first and typical one composed of species of elongate shape, in which the sexes are strongly differentiated, “the males having the abdomen hollowed out beneath and the sides of the cavity elevated into very strong sharp-edged crests. The remaining species are short and broad. in shape and the sexes are alike. The shape of the antennal club is as remarkable for its variation according to the species as is the elytral pattern for its constancy,
The following table gives the differential characters of all the species in a concise form.

This has the form of #. hardwicket and EH. coelestinus, as well as the angularly prominent crests at the shoulders, but it is rather smaller, the elytra are quite shining, except at their hinder extremities, and the club of the antenna is less dilated, more loosely articulated and more asym- metrical. The hind angles of the pronotum are a little more sharply produced. The coloration is practically the same as in 4. coelestinus.
The male has the abdomen excavated in the same way, but with the lateral ridges more sharply elevated, and the tibiae are more regularly curved.

The Museum collection contains one specimen of each sex, referred by Mr. Gorham to #. cruciger, but consider- ably smaller than the type (the specimen figured) of that species, from which it differs also in the narrower prothorax, with more sharply produced front and hind angles. The shoulders of the elytra are a little less prominent than in that species, The club of the antenna in both £. vicinus and H. cruciger is more abruptly dilated than in FL. hardwickes and E. coelestinus, but much less so than in the dohertyv group. ‘The ventral carinae of the male are very sharp and prominent.

This is a member of the second group—cf smaller and shorter-bodied forms. The elytra are smooth and shining, with the shoulders rather square (not broadly rounded, as in #. dohertyi Gorh.), the widest part beyond the middle, and the pattern consisting of four large rounded pale yellow patches, exactly as in EH. dohertyr ‘and EB. cruct ger. The antennal club is short, but larger and broader than in any other known species of the genus, the last two joints being very closely fitted together i in the form of a triangle with almost uninterrupted sides, the preceding one only

very slightly dilated at the end. The club of HL. doherty: is of similar form but less dilated.
The two sexes are almost alike, but specimens with the abdomen more shining (that is, less closely punctured and hairy) and the 6th segment distinctly exserted are apparently the males.
Of the eight specimens mentioned by Gorham under the name of #, “dohertyi six belong to the new species, the two from the Ruby Mines district alone agreeing with his figure.
Genus BoLBoMORPHUS.
The new species of this genus described below is very interesting as a connecting link between Bolbomor: ‘phus and Eucteanus, indicating forcibly the non-significant character of the degree of dilatation of the antennal club, which has been treated as of primary importance in the grouping of the genera, In Hucteanus occurs the extreme degree of dilatation known in the Endomychidae (#. eucerus Arv.), while in the type-species of Bolbomorphus (B. gibbosus Gorh.) this feature is reduced almost to its minimum. In the second described species (B. theryi Gorh.) there is, according to the figure, a distinct widening, and in this (the third species) the antennae are in practically the same condition as in Hucteanus hardwicket Hope, the ty pe-species of that genus, in which they exhibit their least developed phase m Eucteanus. Yn its general form B. sex- punctatus shows a close approximation to the smaller species of Hucteanus in which external sexual differences are absent, and indeed there is no important feature by which to distinguish them, so that we have a series of closely-related forms showing a complete transition in the shape of the antenna from one extreme to the other.

Hab. K. Cuina: Shanghai.
A single specimen collected by Fortune has been in the British Museum Collection since 1854. It appears to be a female.
The elytra are broader at the shoulders and rather less pointed behind than in B. gibbosus Gorh., and their con- vexity is less than in that species. The puncturation of the upper surface is stronger and closer, especially at the sides of the pronotum, which are densely punctured and opaque. The yellow spots are small and round, one placed just behind the shoulder and almost touching the lateral margin of the elytron, another near the last but just within and at the base of the shoulder prominence, and the third remote from these and considerably behind the middle of the elytron. The club of the antenna is very loosely articu- lated and dilates rapidly from base to extremity, where it is about twice as wide as in B. gibbosus.
Genus MrInicntus.
Thelgetrum of Gorham is synonymous with Muilichius, T. ampliatum Gorh., being merely a little more elongate in shape than the other species so far known, and Gibbiger of Cziki, which has been separated solely on account of its thicker antennae, cannot be retained, for the propor- tions of those organs vary with every species. The genus accordingly contains at present six described species, to which several are added here. The genus appears to be Malayan in its distribution and is very well characterised by its hemispherical shape, long and narrow antennal club, widely separated coxae and broadly dilated basal joints of the feet. No sexual differences are known.

The type is unique.
The species is very closely related to the typical M. mgricolis, Gerst. It is bright ferrugineous red in colour, with the pronotum a little darker, the legs and lower surface very dark brown, with the exception of the sides and extremity of the body beneath, and the antennae black, except three or four basal joints, which are very dark brown, and the terminal joint, which is bright yellow. It might be regarded as a colour variety of M. nagricollas, but for the antennae, which are much more than half the leneth of the body, with joints 3 to 8 distinctly diminish- ing in leneth, the 8th about as wide as long. The punc- turation above and beneath is as described for M. nigricollis rerst. (which is unknown to me), but the basal foveae of the pronotum, although extremely short, are deep and broad.

There is a close resemblance to M. fuscipes but, besides the differ-

A series of specimens were taken by Mr. Bryant in December and February upon Mt. Matang in Sarawak. Tt is an almost uniformly brown species, with the antennae black, except the basal four. (sometimes five) joints and the terminal one. The sides of the pronotum and the shoulders of the elytra are rather vaguely paler. The upper surface is rather strongly punctured, especially upon the elytra. The pronotum is strongly narrowed in front and deeply emarginate to receive the head, with the front angles well produced. The humeral calli are very promi- nent. The antennae are rather less slender than those of M. ngricollis, but less compact than in M. ferrugineus. All the joints are elongate except the small 2nd joint and the 8th, which is eae as broad as it is long. The last three form a scarcely perceptible club, the terminal one a little longer than the others.
