did not refer to the sex of his specimens, but it is evident that the female only was known to him. Specimens from the Darjeeling district which I have recently examined reveal that the male is much more remarkable than the female. I propose to call this very peculiar insect

CEPHALIPS, gen. nov.

The head is produced to a sharp angle on each side and the tip is formed by the eye, which is very small and finely facetted. The mandibles are very greatly enlarged, broad and fiat, and each has a strong lateral angulation which forms a repetition of that of the head. Features peculiar to the male are in my opinion insufficient for establishing genera, but in this case the female also is so peculiar that it seems inevitable to separate the species from Glischrochilus. The head in this sex also is extremely broad, the eyes relatively very small. The body in both sexes is much broader than in any species of the older genus, and the scutellum is extremely short and broad, but sharply angular, its sides straight.

author, to be related to the Scolytid~e, should be referred

to this family near Nemosoma, as suggested by the late G. C. Champion.

Two genera, Latol~va and Ancyrona, were formulated by Reit ter and distinguished by the smoothness of the upper surface and the rounded prosternal process of the former compared with the pubescent surface and angulate sternal process of the latter. The number of species referable to these genera is very considerable, and their separation is therefore naturally a much less simple ma t t e r than at first appeared. The shape of the prosternum passes by gradual transition from one type to the other. Species in which it is rounded, as in Latolxva, e. g., A. fryi Lev. and pryeri OH., have the clothed surface of Ancyrona, and vice versd. Until a better subdivision is devised it seems advisable to regard all the species as forming a single genus, for which the name Ancyrona, under which most of them have been ranged, will be the most suitable. The new species here described unites features of both Reitter 's groups.

Ancyrona titan, sp. n.

Testacea, capite, pronoto et scutello nigris vel nigro-brunneis elytrorumque ]ateribus rufo-brunneis, corpore subtus (capite obscuro excepte) pedibusque rufo-testaceis, antennis brun- neis, clara pallida: late ovalis, modice nitida, capite crebre punctato, antice truncato, processubus genalibus desuper apparentibus; pronoto medio subtiliter haud crebre, lateraliter fortiter et crebre, punctato; scutelto latissimo, rotundato, bene punctato ; elytris crebre seriato- punctatis, lateribus excavatis, grosse irregulariter punctatis, corpore subtus lmvi, nitido, processubus genalibus planis, latis, processu prosternali angusto, acuto, antennis gracilibus, articulis 3-7 elongatis, 8 et 9 modice latis.

Long. 10-14"5 mm. ; lat. 6-9 mm.

UGANDA: Entebbe (C. A. Wiggins), Kampala (C. C. Gowdey, June).

This is a giant amongst the generally small insects composing this large genus. I t is even larger than A. p/ana Lev., and differs from it in coloration, absence of the hairy clothing, and non-costate elytra. The sides of the head, pronotum, and elytra, and the extremities of the last, bear extremely minute sparse setm, but the virtual absence of hairy clothing would render it equally permissible to refer the species to Ancyrona or Latolxva.

A. titan is easily recognizable by its nearly black head, pronotum, and scutellum, contrasted with the yellow elytra with reddish-brown margins. The antennae are reddish, with the three large joints forming the very asymmetrical club rather pale.

Family Colydiid~e, Sparactus pustulosus Blackb. is a species of Pristoderus

(-~ Ulonotus) of which I have seen specimens from Queens- land, New South Wales, Victoria, and Tasmania.

The Euxestini, hitherto regarded as aberrant Erotylid~e, have been transferred by Van Emden to the Colydiid~e on account of the tarsi, composed of four joints only, and the antennae inserted under the clypeal margin. I-Ie is no doubt right in making the transfer, but I think a certain degree of relationship with the Erotylid~e should not be overlooked. Although in that family the tarsi are composed of five joints, there is a progressive reduction of the fourth joint, which is sometimes no more than a vestige, as in the genus Idiodacne.

In the Euxestini the last three joints of the antenna are fused together to form a solid club. In the largest known species of the group, Pseudodacne admirabilis Crotch, found in Borneo and the Malay Peninsula, the club differs in shape in the two sexes, that of the male being much larger and broader than that of the female.

Euxestus and Pseudodacne are the only two genera recognized by Van Emden as belonging to the Euxostini, but Euxestoxenus in my opinion cannot be excluded. The structure of the tarsi and antennm is very similar to that found in the other two genera.

I introduced the genus Euxestoxenus in 1925 for a single Indian species, E. striatus. Since that date three African species have reached the British Museum collection which in my opinion may be referred to the same genus. They are undoubtedly related closely to E. striatus, although the antennm have a larger number of joints. Where crowding and contraction of the joints between scape and club occurs, fusion, partial fusion, or reduction of certain joints is a usual consequence, and I consider that undue importance is sometimes attached to the par- ticular condition attained by different species in this way.

Long. 2 mm. ; lat. 1.5 mm. BELGIAN CONGO : Elisabethville (H. S. Evans). Three examples of this species also were found 18 miles

south-west of Elisabethville. This has the same shape and structure as E. testudo,

but is smaller, rather more globular, lighter in colour, and more shining. The legs, especially the front tarsi, are a little shorter and the large single-jointed antennal club is shorter and almost round. The puncturation of the elytra is much less strong and close, the lines of punctures a little irregular and the intervals only feebly convex. The clothing of setm is not composed only of linear series, as in E. testudo, but there is a row of single erect setee upon each interval as well as a general clothing of similar but shorter setze.

Long. 2 ram. ; lat. max. 1.5 ram. ABYSSINIA : Djem Djem, 8000 ft. (H. Scott, Oct.). Two specimens were found in the grass-thatch of a

hayrick. This species closely resembles the preceding in size,

shape, and colour, but it is a longer and less convex insect. The puncturation of the upper surface is also almost identical, but the clothing of setm borne by the upper surface is rather different, the set~e being a little longer and less numerous. Those upon the elytra are all arranged in regular longitudinal rows. The club of the antenna is of the same broadly oval shape and the form of the legs is almost identical.

Family Biphyllid~e. The genera which I proposed to separate under this

name in 1929 are catalogued partly with the Erotylid~e and partly with the Cryptophagid~e, but, as already mentioned, several have escaped inclusion in either.

106 Mr. G. J. Arrow on

The list of species of Diplocoelus, included with the former group in the Junk Catalogue, is also very incomplete. Amongst others a number of Australian species at tr ibuted to the genus by Lea in 1921 and 1922 are omitted. Two of these, D. maximus and sericeus Lea, belong to the genus Althxsia, as does D. leai of Blackburn. In my table of the members of this genus (1929) that name was misplaced by a typographical mistake. I therefore give here an emended key.

Species of the Genus Althmsia. 1 (6). Innermost lateral groove of the prothorax

not interrupted. 2 (3). Upper surface without dense mottled cloth-

ing ; basal groove of pronoturn angulato., leai Blackb. 3 (2). Upper surface with dense mottled clothing ;

tures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . arrowi Grouv. 10 (7). Upporsurfacowithout donsomottled clothing, max ima Lea.

AItha~sia maxima Lea is known to me only from the description. When describing A. acuminata (Ann. & lying. Nat. Hist. (10) iv. 1929, p. 309) I regarded the spined hind margins of the olytra as the most important diagnostic feature, but this is apparently confined to one sex, specimens with and others without the spine having been taken together by Miss Cheesman at Kokoda, Eastern New Guinea. This species rather closely resembles A. pilosa Pascoe, but is rather larger, and, in addition to the more strongly curved basal groove of the thorax and less produced elytra, the club of the antenna is more compact and its terminal joint not elongate like that of A. pilosa.

Diplocoelus angustulus Blackb. was misplaced in that genus. I t is a species of Lyctus.

Family ErotylidEe. Erotylus sphacelatus of Fabricius has been found by

Gebien (Deutsche ent. Zeits. 1906, p. 226) to belong to the

Tenebrionidm. The species of Cypherotylus to which the name is commonly applied, and of which a figure was published by Duponchel (in Mdm. Mus. d'Hist. Nat. xii. 1825, p. 35), must be renamed ; it may be called duponcheli. I have seen a specimen of this handsome insect imported alive into England in a bunch of Brazilian bananas.

The Sumatran Micrencaustes sex-pustulata Gorh. is the same as M. sex-guttata Gorh., described thirteen years previously. Gorham's later description shows that at the time of writing he had entirely forgotten the earlier one. Episcapha semperi Gorh. is also a species of Micren- caustes.

S. AFI~ICA, PONDOLAND : Port St. John (R. E. Turner, Oct., Nov.).

Two specimens of this interesting little insect were found. I t is a very peculiar representative of the sub- family Dacnin~e, with the short rounded shape generally distinctive of the Tritominm, the Dacninae being almost all of elongate form. Brachydacne is very highly convex, and, although very short and broad, the pronotum is

108 Mr. G. J . Arrow on

relatively long and, with the head, measures nearly half the total length of the body. The legs and antenn0e are slender and the tarsi rather long and narrow, with a very small but distinct fourth joint. The antennae have a long, narrow, and loosely articulated club, of which all three joints are transverse. The third joint is nearly twice the length of those preceding and following it. Although in its rounded form of very different aspect the genus may be compared with Microsternus, to which it has some affinity. The structure of the sterna is similar, bu t the prostornum is not pointed in front and only partially covers the mesosternum. The eyes are farther apart, the anten~ee more slender, and the fourth tarsal joint more reduced. The red transverse band which occupies the base of the olytra has its posterior edge slightly waved and is a little wider at the suture and at the shoulders, where the red colour is continued com- pletely round the outer margin.

W. AFRICA: Mann's Quelle, 7400 ft., Mt. Cameroon (Miss M. Steele, Jan., Feb.) ; Nyamkubi Mrs., 7800 ft., Kivu, Belgian Congo (L. Burgeon, Nov.).

A number of specimens were taken by sweeping herbage and one was found in rotten wood.

This is closely related to Penolanguria monacha Kraatz and ovalipennis Arrow, which, on account of their small coarsely facetted eyes and peculiarly shaped tapering elytra, I consider should be transferred to the present genus, hitherto known only from India and Sumatra. P. steelei has the short form and highly convex elytra of P. monaeha, as well as its shining bronze lustre, but its puneturation is very much less strong and close. The

Page 9: XI.—               Notes on some Clavicorn Coleoptera and descriptions of a few new species and genera

some Clavicorn Coleoptera. 109

eyes, as in the other species of the genus, are very promin- ent but very far apart, and more coarsely facetted than in either P. monacha or ovalipennis. The pronotum is broader in front than in either and not quite as convex as in P. monacha. The elytra also are a little less inflated than in P. monacha, but the shoulders, though less de- pressed, are similarly narrowed and the elytra not less tapered. The fore tibiae are distinctly longer than the rest, but this disparity is especially marked in the males. The stridulatory files on the posterior part of the head are rather far apart and consist of minute rounded tubercles.

Family Endomychidm.

Brachytrycherus concolor. Niger vel purpureo-niger, nitidus, tarsis tibiarum et anten-

nature apicibusque fulvo-setosis, ovatus, convexus, lmvis, capite angusto, oculis parum prominentibus, antennis parum gracilibus, articulo 3 elongate, 4-8 quam latitudinem vix longioribus, clara angusta, articulis duobus ultimis trans- versis; pronoto quam longitudinem sesqui longiori, im- punctato, lateribus paulo reflexis, antice leviter arcuatis, postice reetis, fere parallelis, angulis omnibus acutis, levels basalibus fere ad medium productis ; elytris fortiter con- vexis, impunetatis, lateraliter rotundato-ampliatis ; corpore subtus l~evigato, mesosterno late, utrinque carina brevi obliqua signato.

Long. 9 mm. ; lat. max. 5 mm. N. BORNEO : Bettotan, near Sandakan (H. M. Pendle-

bury, Aug.). Several specimens were found. This is an isolated species, differing greatly in shape

from typical members of the genus Brachytrycherus, of which it has the essential characters. Both upper and lower surfaces are extremely smooth and shining. I t is of rather elongate shape, with the head rather narrow, the eyes not very far apart nor very prominent at the sides, the anterm~e not very slender, joints 4-8 not appreci- ably longer than they are wide, the club very narrow, but the last two joints strongly transverse. The pro- thorax is much narrower than the conjoined elytra, not much wider than it is long, with the lateral margins almost s t ra igh t and feebly diverging behind, gently curved and converging in front, and all the angles acute. The basal fove~e are produced almost to the middle of

Page 10: XI.—               Notes on some Clavicorn Coleoptera and descriptions of a few new species and genera

110 Mr. G. J. Arrow on

the pronotum. The elytra are highly convex and strongly rounded at the sides. The mesosternum is transversely rectangular. The legs are stout and rather long, the tibiae straight. The male has a very blunt conical tooth upon the inner face of the front tibia towards the extremity.

Eucteanus latipennis, sp. n. Nigro-violaceus, singulo elytro maculis duabus magnis sub-

rotundatis ornate; latus, valde convexus, vix nitidus, capite crebre punctato, oeulis haud magnis; pronoto angusto, opace, parum distincte punctato, marginibus lateralibus elevatis, antice rotundatis, angulis omnibus acutis ; elytris subnitidis, sat crebre et minute punctatis, maculis pallidis apicibusque autem vix punctatis, humeris haud angulatis sed inflatis et rotundatis, marginibus externis postice paulo deplanatis, apicibus rotundatis, vix productis ; antennis pedibusque gracilibus, illarum clara longa, articulis tribus longitudine fere mqualibus.

Long. 9-10 mm. ; lat. max.. 5.5-6 mm. BVRMA: Mishmi Hills, Chaglon, 3500 ft. (Miss M.

Steele, March). Miss Steele collected four specimens. This species bears a close resemblance to E. eueerus

Arrow, but is more nearly related to E. marseuli Gorh., having an elongate antennal club and narrow prothorax. The latter is opaque, with rather indistinct shallow punctures, the lateral margins elevated, strongly rounded before the middle, and all the angles sharply produced. The elytra are rather feebly shining, scarcely punctured upon the yellow patches and the apices, but distinctly and evenly elsewhere. The pale areas are large, trans- versely oval, and about an equal distance apart longi- tudinally and transversely. The elytra are rather feebly shining, very broad and convex, but not broader behind the middle than in front, the shoulders being dilated and not squared but broadly rounded. The anteun~e are very slender, the club not pear-shaped as in E. eucerus and dohertyi, but more than twice as long as it is wide, its basal joint forming a nearly equilateral triangle.

The sexes are alike in this group of species.

TIBET-BuRMESE FI~ONTIEI% 28 ° 25' N., 97 ° 55' E., 10,000-12,000 ft. (F. Kingdon Ward, Sept.).

In addition to its quite different elytral pat tern and nearly black ground-colour E. elegans has a much more glossy dorsal surface than any other species of the genus. I t approaches E. dohe~tyi Gorh. in this respect, but the punctures of the pronotum and elytra are finer and less close than in that insect. The pronotum is very small, rela- tively short, little narrower in front than behind, with all the angles sharply produced. The elytra are broad at the shoulders, which are rather sharply prominent, short, scarcely dilated behind and bluntly produced at the tips ; each has two large pale yellow patches, which are not, as usual, rounded, but transverse, with finger-like processes from their fore and hind margins exactly as in the genera Trycherus, Engonius, and various genera of Erotylidse. A process from the anterior patch reaches the front margin of the elytra and another almost joins a corresponding process from the posterior patch, so that a dark rectangle results in the middle of the back. The antennse are very slender, the club very loosely articulated and rather narrow.

E. elegans belongs to the section of the genus in which the two sexes are alike.

The description of Amphisternus metallicus Pie applies in all respects to A. armatu8 Gorh., of which the type is in the British Museum. This species is peculiar for its metalliv green surface.

KENYA: Mr. Kinangop, Aberdare Range, 8000 ft. (F. W. Edwards & J. Ford).

Numerous specimens of this insect were collected from the flowers of Cardanus keniensis.

I t is a fairly large species of very distinctive although variable coloration The head, pronotum, andlower surface are black, and the elytra brown, light or dark according to the colour of the scales with which they are clothed. These are occasionally almost uniformly pale, but more often reddish or red and yellow mixed, and a large patch of dark scales of irregularly oval shape and extending from side to side is almost always visible before the ex- tremity of each elytron. The two dark patches are out- lined, except where they reach the outer edges of the elytra, with nearly white scales, and the sides of the pronotum are covered with scales of the same colour. The posterior patches are usually almost black, but may be indicated only by the pale marginal line, and they are occasionally absent.

In 1915 I recorded several synonyms of the common species Attagenus undulatus Motsch. Nitidula tomentosa Walker, the mutilated type of which is in the British Museum, proves to be the same and yet another synonym is Pseudotelopes simoni Pic, according to a specimen so named by M. Pie.

Specimens of a species of Attagenus from Uganda referred at various times to M. Pic have been identified by him as A. nigroapicalis Pic, as A. rufimembris Pic, and as a variety of A. rufiventris Pic, indicating that he regards the three names as synonymous. Whether he is right in this I am not able to judge.

Thaumaglossa atricolor Pie, according to specimens named by that author, is the very widely distributed T. rufocapillata Redt.

Family Paussid~e.

Although this is not a Clavicorn family, it will not be entirely out of place to record here that Paussus australis Blackb. is an Abyssinian species, Paussomorphus chevrolati Westw. All the Australian Paussid~e belong to the primi- tive Cerapterin~e, and the presence of this representative of the true Paussin~e in Australia must have been accidental. Blaekburn's specimen is now in the British Museum. The Queensland locality was probably at tr ibuted to it in error.

XII . - -New Asiatic Telenominm (Hym., Proctotrupoidea). By G. E. J. NIxoN, B.A., Department of Entomology, British Museum of Natural History.

THE material on which the following paper is based has been received from the Imperial Insti tute of Ento- mology for identification.

The types of all new species have been deposited in the collections of the British Museum.

Subfamily TELENOMI~V~'.

The generic classification of the Telenomin~e is largely in a state of confusion. I think, therefore, that a few remarks concerning the position of the species described below will not be inappropriate.

Kieffer has been, to a large extent, responsible for the existing chaos, owing to his objectionable practice of relying on inadequate descriptions for the inter- pretation of species. Having satisfied himself as to the correct identity of the host of species described by Walker, Ashmead, Thomson, and others--a conclusion frequently based on assumption, since the authors cited were seldom explicit about the very characters on which he lays stress,--Kieffer proceeded to redistribute them within a scheme of genera formulated by himself. For example, there is Liophanurus Kieff., a motley assortment of species, belonging to Microphanurus Kieff., Telenomus
