A List of the Longecorn Coleoptera collected by Signor FEA in Burma and the adjoining regions , with descriptions of the new Genera and species by CHARLES J. GAHAN, M. A., of the British Museum (Nat. History). (Plate 1). The Longicorn Coleoptera recorded in the following list amount to a total of about 240 species. Of this number 90 are now described for the first time and, with 3 previously described by D.' Gestro, give 93 as the number of new species contained in the collections made by Signor Fea. But of these not a few were already represented in other collections by specimens which had been brought from Burma, or, as was more often the case, from North India. Where it seemed desirable, as ten- ding to throw some light upon the distribution of the species, I have added after each the other localities from which it was known, in addition to those indicated by Signor Fea’s specimens. A comparison of these localities will show that the Longicorn fauna of Burma has very much in common with that of Nepal, Sikkim and Assam in Northern Hindostan. This is more parti- cularly true, perhaps, of mountain species, some of which range as far south even as Sumatra and Java. There is less resemblance between the Longicorns of South India and Burma, though a few species are common to both which have not so | 95678 6 C. J. GAHAN far been recorded from North India. Among the species that appear to be confined to Burma may be more especially men- tioned those of the fine genus Arctolamia described by D." Gestro, and some large species which I have placed in the genus Niphona. Fea’s collections have furnished two species of Atimura, one of which is indistinguishable from an Australian species described by Pascoe. Of the remaining species of Atimura two are from the Malayan region, and one from Japan. It is pro- bable that this genus is represented by a much larger number of species, but that owing to their small size and the protection afforded them by their great resemblance to little bits of sticks they have to a great extent escaped the notice of collectors. The new species, for which I have proposed the genus Estigme- nida, is also remarkable for its striking resemblance to a com- mon Oriental Hispid Estigmena chinensis, Hope. The majority of the new species belong to the groups C/lytinae, Mesosinae, Ni- phoninae and Obereinae, and it may be found that, owing to their small size and the difficulty of identifying species in these perplexing groups, some of them have already been described. In identifying some of the more difficult members of the group Callichrominae 1 was indebted to the late M.' Bates for his usual kind assistance. While to M." Pascoe and to M.* René Oberthiir I have to render thanks, for the facilities they gave me in examining types from their collections. PRIONIDAE. 1. Cyrtognathus (Ba/adeva) Walkeri, Waterh., Trans.

Pascoe’s collection by a single specimen from Sylhet. This specimen does not differ by any very important characters from the unique type of Aegosoma 8 Cc. J. GAHAN costipenne, White (Megopis) (Longic. Brit. Mus., p. 28, pl. 2, fig. 2) which also came from Sylhet in Assam. The question as to whether these differences are specific or merely individual must, however, be left in abeyance. It can only be settled by the examination of a larger series of examples. 12.

In the single example taken, the front and the upper side of the head are dark brown; and the small prothoracic spines are somewhat more distinct than in the other examples of T. calli- dioides that I have seen. It ought perhaps to be referred to T. nigriceps, Pasc., but the characters (with the single exception of the colour of the head) by which M." Pascoe has distinguished the latter species do not well apply to the present variety. 14. Tetraommatus insignis, sp. n. (P/. I, fig. 1). Ferrugineo- lestaceus, sparsim pubescens; prothorace antice posticeque transversim sulcato, sulcis infuscatis, lateraliter utrinque tuberculo parvo acuto armato, bast constricto; dorso prope basin longitudinaliter haud profunde bisulcato: elytris dense punctatis, flavo-testaceis, pone medium plaga fusca signatis; corpore subtus pedibusque nonnithil piceo-rufescentibus. Long. 10-11 mm. Thagata in Tenasserim; one example. The British Museum collection contains examples from the Andaman Islands. Head and prothorax dull ferruginous-red. The length of the prothorax to its median breadth in the ratio of 3 to 2. The prothorax is closely but somewhat obscurely punctured ; its sides are slightly rounded, and each is armed with a small but sharp and distinct tubercle; the constricted basal part of the protho- LONGICORN COLEOPTERA FROM BURMA 9 rax is preceded by a slightly arcuate transverse groove; there is a feebler groove close to the anterior margin, and on the posterior part of the disk there are two shallow longitudinal grooves which pass in front into a broad shallow longitudinal depression. Both the transverse and longitudinal grooves are more or less infuscate. Scutellum testaceous. Elytra thickly punctured ; yellowish-testaceous, with a brownish patch, formed by two oblique bands which pass outwards and backwards from the suture on each side between the middle and posterior third, and by the dark borders of that portion of the suture which lies between these bands: the posterior bands are short, the anterior bands extend farther outwards, and, near the margin, take an almost directly transverse direction. 15.

This species oc- curs also in the Philippine Islands (type); and in North India — Allahabad and Nepal (Brit. Mus. collection). Examples from Borneo, constituting the H. morosus of Pascoe, do not seem to me to offer any definite characters by which they can be distin- guished from the above. The species appears to be subject to great variation in size. 21. Pachydissus (Diorthus) simplex, White. — Hammaticherus simplex, White, Cat. Longic. Brit. Mus., p. 130 (W.

Malewoon in Tenasserim. One small example. The localities indicated above, to which may be added Siam and Java, evi- dence the wideness of distribution of this species. Whether it is an Oriental species, which has been transported to West Africa, or an African species which has been carried to the East, I am unable to decide. 22. Pachydissus (Margites) exiguus, sp. n. Fuscus, griseo leviter pubescens; antennis pedibusque piceo-rufescentibus, pube grisea te- nuiter obtectis; prothorace supra intricate haud fortiter rugoso, lateribus irrequlariter rotundatis; antennis quam corpore paullo longioribus, articulis 3° et 4° apice viv inerassatis, 3° quam 1° vel 4° paullo longiort. Long. 11 mm. One example taken at Mandalay. This species resembles P. (Margites) egenus, Pasc. in coloration, but is of much smaller size. The prothorax has a thin unicolorous greyish pubescence. LONGICORN COLEOPTERA FROM BURMA 1l The third and fourth joints of the antennae are scarcely thickened towards the apex ; the fourth is about equal in length to the first ; the third and fifth are subequal, each a little longer than the fourth. 23. Dymasius fulvescens, sp. n. (Pl. I, fig. 2). Piceo-fuscus; ca- pite, prothoracis maculis elytrisque pube fulvo-grisea opaca sat dense obtectis; prothorace quam latitudine longior?, supra intricato-rugoso, lateraliter parum rotundato ; elytris postice gradatim angustatis , apicibus truncatis, ad suturam spinosis; corpore subtus, pedibus antennisque griseo leviter pubescentibus, antennis quam corpore paullo longioribus, articulo 3° quam 4° fere duplo longiori, articulis a 5.° ad 10.™ apice intus spinoso-productis. Long. 20 mm. Hab. Carin (Ghecu): Alt. 1300-1400 metres. One example. Pitchy brown. Head with a rather close fulvous-grey pube- scence, which is wanting only in the somewhat circular depres- sion limiting the frontal plaque, and in the short shallow groove between the antennary tubers. Prothorax longer than broad, slightly rounded at the sides, narrower ip front than at the base, intricately and rather strongly rugose above and at the sides; with a fulvous-grey pubescence limited to the anterior border and to a few patches on the anterior part of the disk. Scutellum and elytra clothed with a dense dull fulvous-grey pubescence, which almost completely hides the underlying derm. Elytra gradually narrowed from base to apex, each truncate behind, and spinose at the suture. First joint of the posterior tarsus as long as the two succeeding joints combined. Antennae (Q?) surpassing the elytra by about the last two joints ; the fourth joint perceptibly shorter than the scape, and scarcely more than half the length of the third joint; with the joints from the 5. to the 10.® spinosely produced at their inner apex, each about equal in length to the 3.727; 11.' scar- cely longer than the 10.t 24. Mallambyx ? sp. Carin Mts., Asciuii Cheba. One imperfect example. As the antennae are wanting it is impossible to refer this species with certainty to any particular genus. It seems to me to belong to Mallambyx or perhaps to a new genus. 12 Cc. J. GAHAN 25. Trachylophus sinensis, Gahan, Ann. & Mag. Nat. Hist., Ser. 6, vol. II, p. 60. Carin Mts., district of Gheca; Alt. 1300-1400 m.; also South China, ? Hong Kong (Brit. Mus. collection). The occurrence of this species as far South as the Carin Mts. makes me inclined to believe that the differences upon which I relied for the separation of examples from Java, under the name of T. approximator, may be of an individual rather than of a specific character. 26.

Stromatium asperulum, White, Cat. Longic. Brit. Mus., p- 300. Teinzd in Upper Burma. One example. Also occurs in North India, South China, Siam and Penang. 30. Hesperophanes erosus, sp. n. Piceo-brunneus, pube breve griseo-brunnea, supra maculatim disposita, vestitus; capite sat dense pubescente, supra linea media impresso: prothorace supra convexo, obsolete punctulato, maculis longitudinalibus irreqularibus griseo- brunneis, dorso antice in medio punctis paucis magnis haud pro- funde impresso; scutello griseo; elytris crebre fortiterque punetatis, pube griseo-brunnea maculatim disposita, utrisque lineis duabus obsolete elevatis, apicibus rotundatis,; corpore subtus, pedibus anten- nisque leviter pubescentibus; his medium elytrorum paullo exceden- tibus. Q Long. 23 mm. One example, taken at Meetan in Tenasserim. Of a reddish brown colour, somewhat darker above. Head with a rather dense LONGICORN COLEOPTERA FROM BURMA 13 greyish brown pubescence; with a median impressed line above. Prothorax convex above and below, strongly rounded at the sides; with some irregular longitudinal spots or patches of greyish brown pubescence, the spaces between which are obso- letely punctured and opaque; with a few large but shallow punctures on the middle of the disk anteriorly. Elytra strongly and very thickly punctured, each with two very feebly raised longitudinal lines; with a short closely laid pubescence disposed in irregular and partly confluent spots or patches; with the naked intervening spaces somewhat glossy; apices obtusely rounded. Body underneath, legs and antennae with a rather thin greyish brown pubescence. Antennae in the female reaching a little beyond the middle of the elytra. This species is founded upon a single female specimen taken at Meetan in Tenasserim. In the absence of the male sex, it is uncertain whether the species should be referred to Stromatium or Hesperophanes. ; 31. Gnatholea eburifera, Thom., Class. des Cérambycides, p. 375.

A widely distributed species. The Oemona philippensis of Newman (Entomologist I, p. 246) is 14 Cc. J. GAHAN distinct from this species, and is to be referred to the genus Examnes of Pascoe. 36. Obrium posticum, sp. n. Mulvo-testacewm; capitis fronte, pe- dibus (dimidiis basalibus femorum exceptis), elytrorumque apicibus piceo-nigris; antennis articulis 4 basalibus nigris, ceteris obscure fulvis. Long. 9 mm. Mandalay. One example. This species has the general appea- rance of Obrium cantharinum, Linn. It is of about the same size; and the punctuation is very similar in the two species. It may be distinguished by the black front of the head, the black apex of the elytra and the black legs. The prothorax ap- pears slightly broader, in proportion to the size of the insect, than in O. cantharinum; and the tubercle on the posterior median part of the disk is almost quite obsolete. Ibidionidum, g. n. Head projecting; front declivous, short, separated from the epistome by a transverse groove. Eyes prominent, coarsely facetted. Antennae a little longer than the body in both sexes, with the scape curved and gradually thickened towards the apex, the second joint short, the third scarcely more than twice as long as the second, the fourth a little longer than the third, the fifth and following joints subequal, each much longer than the fourth. Prothorax elongate, cylindrical, with a conical tubercle at the middle of each side, constricted behind the base of the tubercles, and also, but less strongly so, in front of them. Elytra a little more than twice as long as the prothorax, gradually narrowed posteriorly, with the apices rounded. Pro- and meso-sterna simple, the former dilated behind so as to complete the closure of the anterior cotyloid cavities. Anterior and intermediate cotyloid cavities completely closed in on the outside. Legs moderately long; femora abruptly clavate at the apex, pedunculate at the base. Abdomen much narrowed towards the apex. Male. First abdominal segment elongated, equal in length to the four succeeding segments combined. LONGICORN COLEOPTERA FROM BURMA tS Female. First and second abdominal segments elongated, the first a little longer than the second, the latter as long as the succeeding segments combined. 37. Ibidionidum Corbetti, sp. n. (Pl. I, fig. 3). Sparsim ciliatus, testaceus; prothorace quam latitudine basis duplo longiore, supra ulrinque leviter binodoso, sparsim ciliato; elytris testaceo-fulvis , griseo subtiliter pubescentibus, seriatim punctatis, punctis seligeris. Long. 7-10 mm. Hab. Burma. Two examples, a male and female, were captured by M.‘ Fea at Yenang Young; the species has also been taken at Paungdé by M." G. Q. Corbett. The elongated thorax, somewhat raised and curved anteriorly, gives this little species the aspect of one of the /bidioninae. Its characters show, however, that it belongs to the Obrionides. 38. Thranius simplex, sp. n. Fusco-testaceus, corpore sublus pe- dibusque testaceis, his clavis femorum piceis, antennis fusco-ferru- gineis articulis 8°, 9°-que testaceo-fulvis: capile prothoraceque griseo- flavo pubescentibus, hoc antice lateraliter compresso, dorso gibboso et in gibbo summo sub-asperato: elytris [usco-ferrugineis, crebre fortiterque punctatis, utrisque linea longitudinalt paullo elevata et ad basin extremam tuberculo parvo instructis , apicibus utrisque in spinam productis. Long. 20 mm. Carin Mts. (district of Ghecu). One example. This species may be distinguished from 7. gibbosus (with which it agrees somewhat closely in structural characters) by the rather dark brown colour of the entire elytra. So far as I can judge from the description of Singalia, and of its type species, this genus, which Lacordaire placed in the group of the Saperdides, appears to me to have been founded upon the Thranius gibbosus of Pascoe. Lacordaire himself reco- gnized that the genus presented characters which were quite unusual in the group. But I feel strongly convinced that he overlooked the fact that the characters were not only foreign to the group, but even to the sub-family of the Lamiidae itself. Lacordaire was not unacquainted with the genus Thranius, for he has given a very full description of it in its proper place. 16 Cc. J. GAHAN Bates has also added to the genus Singalia a species from Japan. I have seen the type of this species (S. rufescens, Bates, Journ. Linn. Soc, XVIII, p. 258), which is in the collection of M." Lewis. It belongs to the genus Thranius, and somewhat resembles the species described above, but is shorter and stouter in form, and not quite so dark in colour. 39. Pyresthes birmanica, sp. n. «. Nigra, prothoracis dorso (margine antico excepto) elytrisque rufis, abdomine rufescente basi medio nigro; prothorace antice valde sub-abrwpteque constricto, supra transversim haud fortiter striato, opaco, macula parva medio disci levi, polita, sublus rugoso-punctato; scutello nigro, postice acuminato: elytris erebre haud fortiter punctatis, opacis, apicibus rotundatis, sulura brevissime mucronatis, lateribus paullo pone basin leviter sinuatis: antennis corpore fere aequalibus, articulo 3° quam 1° vel 4° longiori. Q. A mare differt antennis brevioribus, prothorace antice mi- nus abrupte constricto, supra rugoso-punclato, abdomine omnino rufescente. Thagata (%) and Moulmein (¢@) in Tenasserim. In the male type from Thagata the prothorax is rather strongly and some- what abruptly constricted at the apex; between this and the mid- dle its sides are slightly dilated and rounded, and, between the middle and the base, feebly sinuate; the upper side is crossed by some feeble and not very regular ridges, and is without any distinct signs of punctuation. The elytra are only slightly sinuate on each side just behind the base, and not distinctly emarginate as in P. haematica, Pasc.; they are entirely red, with the exception of a slight infuscation on the anterior part of the suture, and are nowhere glossy, the punctures being closely and evenly distributed over the whole surface, and not much larger towards the base than at the apex. The third joint of the antennae is a little longer than the first or fourth. The female example, taken at Moulmein, differs from the male just described in having much shorter antennae ; its pro- thorax is less abruptly constricted at the apex, and has the upper surface very closely and somewhat rugosely punctured ; ee LONGICORN COLEOPTERA FROM BURMA 17 its abdomen is entirely of a dull reddish tint. The agreement in other respects is, however, so close, that I have no hesitation in referring it to the same species. P. scapularis, Pase., seems (so far as I can judge of it from the figure and description) to be nearly related to the present species. 40. Pachyteria superba, Gestro, Ann. Mus. Civ. di Genova, Ser. 2. vol. VI, p. 128. Taken at Bhamo in Upper Burma. 41. Chloridolum alemene, Thoms., Systema Cerambycidarum. Appendix, p. 568. This species is represented by examples which may be ar- ranged in two series according to their size, but which show no structural character by which I can distinguish them. The larger forms were taken at Carin (Asciuii Cheba) Alt. 1200-1300 m. The smaller variety was taken at Carin (Cheba). Alt. 900-1100 m., and also at Thagata in ‘enasserim. 42. Leontium sinense, Hope, Proc. Ent. Soc. Lond. 1841, p. 63; Trans. Ent. Soc. Lond., IV (1845), p. 17. es One example from Carin (Cheba) Alt. 900-1100 metres. In the catalogue of Gemminger and Harold this species is to be found placed as a synonym of ZL. argentatus, Dalm. The two species are, however, distinct. In sémense the joints of the anten- nae from the 7.'" to the 10. are each acutely angular at the inner apex; in argentatus the joints from the 5." to the 10. are each produced into a spine at the inner apex. The apex of the last ventral segment in the female of sinense is distinctly emarginate; the corresponding segment in argentatus (9) is rounded and entire at the apex. L. sinense is most nearly allied to L. subtrwncatum, Bates, which it resembles by its obtusely rounded or subtruncate apices of the elytra; but from which it is to be distinguished by the structure of the prothorax, 43. Polyzonus flavocinctus, sp. n. %. Viridi-metallicus; protho- race transversim strigoso, strigis medio dorsi intricato-confluentibus; pronoto antice in medio paullo rotundato-producto; elytris fascus C. J. GAHAN. 2 18 Cc. J. GAHAN duabus angustis flavis, atro-violaceo limbatis, ornatis; corpore subtus argenteo-sericeo, segmento quinto abdominis leviter sinuato, fere transverso-truncalo, sexto sinuato-emarginalo. A single male specimen was taken at Carin Mts. (Cheba district) at an altitude between 900 and 1100 m. The species occurs also in Tenasserim. This species closely resembles P. bizonatus, White; but differs from it as follows: Prothorax more regularly strigose towards the sides of the disk; the anterior margin of the pronotum somewhat obtusely produced in the middle. Elytra with a gla- brous rugose-punctate area, somewhat cordate in shape, just behind the scutellum. (The corresponding area in P. bizonatus is bluish-black and opaque and not more strongly punctate than the rest of the surface). The posterior margin of the fifth abdo- minal segment in the male is almost directly transverse, that of the sixth segment is sinuately emarginate. (In P. bizonatus both segments are deeply and sinuately emarginate behind). The present species does not differ from P. tetraspilotus, Hope . by any good structural characters, and may possibly prove to be only a variety, distinguished by having two transverse bands, instead of four spots, on the elytra. 44.

Hist., Ser. 6, vol. V, p. 54, pl. VII, fig. 1. Carin Mts. (district of Cheba); alt. 900-1100 metres. One example. This species was described from a single specimen obtained by M." Hampson in the Nilghiri Hills, South India. It is one of those intermediate forms that connect the genera Xylotrechus and Clytus. I have placed it in the former genus, owing to the presence on the front of the head of a median longitudinal groove with raised edges in the form of carinae, and of, a short sharp edge or carina on each side just over the antennary con- dyle. 52. Xylotrechus Gestroi, sp. n. (PZ. I, fig. 4). Capite prothoraceque flavo-pubescentibus ; prothoracis dorso signo cruciformi fusco cujus brachiis macula triangulari utrinque sublatis; lateribus utrisque macula parva rotunda fusca; elytris fusco-velutinis, fasciis flavis, una prope basin literae « parum simili, una submedia triangulart, lertia ad apicem transversa, ornalis; antennis pedibusque testaceis, femo- ribus posticis apice infuscatis. Long. 11. Lat. 3 mm. One example taken at Shwegoo on the Upper Irrawaddy. Head and prothorax with a yellowish pubescence. The front of the head with a median black line; obsoletely grooved between the lower lobes of the eyes, and with a short sharp edge on each side just over the antennary condyle. Prothorax rounded at the sides, marked above by a dark brown figure somewhat resembling a cross whose arms are supported on each side by a triangular or nearly oblong spot; on each side of the. pro- 20 C. J. GAHAN thorax there is a small rounded fuscous spot. Scutellum yellow. The elytra may be described as dark velvety brown, with yel- lowish bands, of which the first, near the base, is somewhat roughly « shaped; the second triangular, with its apex just in front of- its base behind- the middle, and its sides slightly concave; the third is a transverse fascia occupying the apical fifth but without reaching the outer margin. That part of the elytra between the basal margin and the « shaped patch is testaceous in colour and is partly clothed with yellowish pube- scence. The apices are truncate, each very shortly mucronate at the outer angle. Body underneath with a yellowish pube- scence; each of the last four abdominal segments dark brown and nitid anteriorly. Legs and antennae testaceous, with the hind femora infuscate towards the apex. The peculiar marking of this pretty little species will admit of its being easily recognized. I have named it in honour of D.* Gestro who has already done so much to advance the study of Coleoptera. } 53. Xylotrechus quadripes, Chevr., Mém. Soc. Roy. des Sciences de Liége, vol.

Palon in Pegu one male. The species occurs also in India — Sylhet and Madras — and in Siam; and is of economic importance, in- asmuch as it is injurious to the coffee-plant (vide Dunning, op. supra cit.). Chevrolat described the female. In this sex the front of the head has five nearly parallel and equidistant raised lines or carinae, of which the two intermediate are shorter than the rest and do not extend to the vertex. In the male the front of the head has two elongate, very finely granular and opaque black spots, one on each side between the median and the outer raised lines, and each is bounded by a very narrow and slightly raised line. In other respects, a slight difference in the length of the antennae excepted, the two sexes closely resemble each other. LONGICORN COLEOPTERA FROM BURMA 21 54. Xylotrechus Phidias, Newm. — ? Clytus Buqueti, Lap. & Gory, Monograph. des Clytus (1841), p. 86, pl. 16, fig. 99. — Clytus Phidias, Newm., The Entomologist, vol. I (1842) p. 246 (7). Two examples (7 and @) taken at Thagata in Tenasserim. Male with a thin greyish pubescence on the head and pro- thorax, with a faint sub-nude blackish patch on the middle of the prothorax posteriorly. Head and prothorax of the female with a yellowish pubescence ; with a distinct black band ex- tending along the middle of the pronotum almost from the base to the apex, and widening out posteriorly; with a rounded black area or spot on each side of the prothorax. The bands of the elytra in both sexes are as represented in the fig. of X. Buqueti, L. & G. (loc. supra cit.) The female differs further from the male by the form of the last dorsal segment of the abdomen ; this segment is strongly emarginate at the apex in the female, and is rounded and not emarginate in the male. The single male specimen in the present collection agrees well with the male type of X. Phidias, Newm. The female resembles closely the figure of X. Buqueti, L. & G. in all but the colour, of the pubescence on the head and prothorax which in Buqueti is des- cribed, and also shown in the plate, to be cinereous grey and not yellowish. The black spots on the sides of the prothorax are also larger than in Buquet/; though two female examples from Burma in the British Museum have these spots smaller than in the female taken by Signor Fea. It is possible that X. Buqueti has been described from the male of a very closely allied species, and it is with doubt, therefore, that I regard it as synonymous with X. Phidias. 55. Xylotrechus vicinus, Lap. & Gory. — Clytus vicinus, Lap. & Gory, Monograph., p. 38, pl. 8, fig. 47. Taken at Rangoon; at Meetan and Kawkareet in Tenasserim. It occurs also at Moulmein in Burma, and at Calcutta and Bhotan in N. India. The males differ from the females by the same characters of the last dorsal segment as in X. Phidias, Newm. 56.

Prothorax rounded at the sides, somewhat widened from the base to beyond the middle and thence strongly narrowing to the apex; somewhat sparsely asperately punctured along the middle above, the disk with two black spots or a transverse black patch. The first cinereous band of the elytra runs across the base on each side from the scutellum to the humeral de- pression where it is slightly turned backwards; the second begins at the suture a little behind the scutellum, diverges from the suture while passing backwards for some distance, then curves round to take an anterior and outward direction, and is again sharply bent backwards just before reaching the outer margin: the third band, placed just behind the middle, is narrow and slightly oblique in its outer half, and is angulately dilated both anteriorly and posteriorly at the suture; the fourth is a rather broad and somewhat oblique band placed at the apex. The body underneath is closely covered with an ashy-white pubescence. The legs are black, with a faint greyish pubescence; the first joint of the posterior tarsi is nearly three times as long as the two succeed- ing joints combined. The female differs from the male, not only by its shorter antennae, but also by the yellowish-grey colour of its elytral bands, and by having an illdefined longitudinal yellowish-grey band on each side of the prothorax above. This species seems closely allied to P. cinereus, L. & G. (Mon. LONGICORN COLEOPTERA FROM BURMA 23 des Clytus, p. 68, pl. 13, fig. 79), and to P. fuliginosus, Chevr. — the type of Chevrolat’s genus Amauresthes. It has a very similar style of marking to the former, but differs from both by the sparser punctuation along the middle of the pronotum, and by the black patch on the middle of the disk. I do not find that Amauresthes can be distinguished by any definite characters from Perissus. The three species just mentioned agree in having their prothorax a little bulged out just behind the middle; but, so far as I can see, there is no other character of the least generic importance by which they differ from typical species of Perissus. The Clytus cinereus of Lap. & Gory (—C. Duponti (Dej.) Muls.) appears under the genus C/ytus in Reitter’s Catalogue of European Coleoptera: but if the genus Perissus is to be re- tained, as, for convenience sake, I think it may, it ought to include C. cinereus. 57. Perissus persimilis, sp. n. Precedenti similis, sed prothoracis lateribus magis parallelis, discoque sine plaga transversa nigra, scu- tello omnino cinereo. Elytrorum fasciis ante-mediis minus contortis. Long. 8 mm. Two examples taken at Thagata in Tenasserim. This species has at first sight a strong resemblance to the preceding, but may be distinguished by its more parallel-sided prothorax, which is moreover without a transverse black space above. The scutellum is wholly cinereous. The antemedian band of the elytra begins a little behind the scutellum, passes back- wards and outwards, diverging rather strongly from the suture, is then turned slightly forward, and reaches the outer margin without undergoing a second bend. 58. Perissus mutabilis, sp. n. Capite prothoraceque rufo-ferrugi- nets aul nigris, minute granulosis, griseo subtilissime pubescentibus,; prothoracis dorso plaga transversa sub-nuda, margine basali utrin- que albescente; scutello albo; elytris nigro-opacis, fusciis griseis et cinerets ornatis, abdomine et fasciis pectoris cinereis; pedibus anten- nisque nigris, his griseo-pubescentibus. Long. 8-14 mm. Thagata in Tenasserim. 24 C. J..GAHAN Head and prothorax minutely granulose, their colour varying from ferruginous red to black. The prothorax with a transverse sub-nude space on the middle of the disk. Scutellum and the latero-basal margins of the prothorax whitish. Elytra dull vel- vety black with ashy and grey markings, of which the first consists of a band on each which commences at the suture just behind the scutellum, passes obliquely backwards for some dis- tance without strongly diverging from its fellow, and is then directed almost straight outwards so as nearly to reach the external margin, the second is a transverse or slightly arcuate band crossing the elytra at about the middle, and gradually becoming wider towards the suture so as to have a somewhat shortly triangular form; the third is a transverse band, of a somewhat darker grey colour, which occupies a little more than the apical fifth. The first two segments of the abdomen, and two bands on each side of the breast (one longitudinal and one oblique) are of an ashy-white colour; the hinder segments of the abdomen have a darker grey pubescence. The head in this species is more flattened between the an- tennae and more regularly rounded from the vertex to the front than in other species of the genus. In this respect it approaches the African genus Calanthemis, Thoms. For the four following species I use the generic term Calo- clytus (') in preference to C/ytanthus, believing that the latter name would be better restricted to certain Central American species which are distinguished by having a longitudinal groove or depression on each side of the elytral suture limited on the outside by a more or less distinct carina, The genus Clylanthus, thus restricted, is more allied to Ochresthes, than to the Euro- pean and Asiatic species hitherto included in the former genus. 59.

Elytra black with greyish markings — an x-shaped figure extending from the base to near the middle, and inclosing an oval spot on each side; a trans- verse band, dilated at the suture, placed behind the middle; and an oblique fascia on each at the apex; apices of elytra obli- quely truncate; outer angles acute, sub-spinose.

Elytra black, with dull-cinereous markings , consisting of (1) a transverse basal fascia; (2) a narrow band on each beginning at the suture just behind the scutellum, di- verging from the suture as it passes back for a short distance, and then curved so as to run outwards and slightly forwards without, however, reaching the external margin; (3) a trans- verse band placed just behind the middle and having the form of a short triangle with its apex placed anteriorly at the suture; (4) a rather broad transverse band at the apex. Body under- 26 Cc. J. GAHAN neath with a greyish pubescence, passing to whitish on the sides of the breast and abdomen. The antennae of the female are piceous, with a greyish covering, and reach to about the beginning of the posterior fourth of the elytra. The style of marking of this species somewhat resembles that of Perissus mutabilis; but the species may be easily distin- guished from the latter by the greater length of its antennae, and, especially, by the form of the head, which in Perissus is broad and level between the antennae, but in Caloclylus is nar- rower and concave in this region. 62.

Prothorax elongate, cylindrical, very slightly rounded at the sides, dull ferruginous-red with the anterior margin black, the basal margin whitish. Scutellum white. Elytra dark brown, with ashy white markings; consisting of a small transverse spot on each, close to the suture, at about the anterior fifth: a narrow oblique band on each at the middle which runs forward along the suture almost up to the anterior spot, and a narrow trans- verse band placed at some distance before the apex. Between the last band and the apex the elytra have a dark grey pubescence. Apices of the elytra transversely truncate. This species is closely allied to D. semdluctuosus, White, from which it differs, inter alia, by the colour of the prothorax, and by having the median band of the elytra more oblique. 66.

Prothorax with four black spots placed transversely in front of the middle, of which two only are visible when looked at from above, with one, or three, narrow and less distinct black spots, running longitudinally between the middle and the base. Elytra each with a V-shaped black figure between the middle and the base, the inner branch of which is joined to its fellow of the opposite side by a short transverse bar just behind the scutellum, so that the combined figures are somewhat in the shape of a W; with a crescentic black spot or fascia behind the middle, the horns of which are prolonged anteriorly, the inner horn joining, at the suture, the corresponding one of the other elytron; with a somewhat rounded black spot about midway between the crescentic spot and the apex. This species has (notwithstanding the difference in markings) a general resemblance to Grammographus Horsfieldi, White, and I should have included it in the latter genus, were it not that certain joints of the antennae are shortly spined —a character wanting to G. Horsfieldi. 67. Demonax reticollis, sp. n. (Pl. I, fig. 7).

Head, prothorax, legs, antennae and underside of the body with a greyish pubescence; the basal margin of the prothorax on each side, and the sides of the breast and two first abdominal segments whitish. Prothorax slightly rounded at the sides, co- vered above and at the sides with thin feebly raised lines which run together to form a very fine reticulation.

The antennae in the female (the only sex represented) are somewhat shorter than the body, with a rather long and slender-spine at the outer termination of the third and fourth joints. 68.

The specimens taken at Cheba differ slightly from the re pe as follows: — The two black spots of the prothorax are more distinct. The second ashy-grey band of the elytra is not in the form of a short broad W as in the type, but is interrupted at the suture so as to have the appearance of a distinct and sepa- rate V on each elytron. 69.

Antennae a little longer than the body; joints 1* and 4.t8 subequal, each scarcely more than half as long as the third ; fifth and following sub-equal, each longer than fourth and shorter than third. Prothorax with its length to breadth in ratio of 3 to 2; somewhat rounded at the sides; slightly cons- tricted at the base, narrowed from the middle up to the anterior margin, with a very feeble constriction about midway between these two points;.covered on all sides with a somewhat golden pu- bescence which is rather duller on the upper side. Elytra strongly punctured; chalybeate-blue, with a golden pubescence which more or less closely covers the upper surface with the exception of two transverse and slightly oblique bands on each elytron near the middle, and a less clearly defined longitudinal band passing from the shoulder to join the anterior of the two transverse bands. The arrangement of the pubescence in this species somewhat resembles that of Glaucytes interrupta, Oliv. This character enables it to be easily distinguished from Polyphida clytocdes, Pasc., in which the elytra have a silvery pubescence arranged in a pat- tern similar to that of many Clytinae. 72.

Long. 8 mm. Carin Mts. (Ghecu’ district) alt. 1300-1400 m. Black, with the exception of the bases of the femora which LONGICORN COLEOPTERA FROM BURMA 31 are yellowish-white. Furnished with some long, rather sparsely scattered sub-erect setae. Upper part of the head, the prothorax and the scape of the antennae minutely and very closely pun- etured, with the punctures on the middle of the pronotum running together in a longitudinal direction and imparting to the disk a slightly rugose appearance. Elytra with strong, somewhat transversely elongated, punctures arranged in four rows on each. The inner-most row is close to the sutural edge, and is made up of smaller punctures than those of the other rows; the second runs along the middle of the dorsal part of the elytron and has on its inner side, near the base, a feebly raised line; the third and most distinct row sets out from the basal depression just above the shoulder, and, along its inner border, has a clearly marked raised line; the fourth row runs back from the humeral prominence, and its punctures are slightly distant from one another. The raised lines and the large punctures do not extend on to the posterior sixth of the elytra; but this part, and the interstices over the remainder of the elytra are very minutely and closely punctulate, and covered by a very faint dark-brown or blackish pubescence. The apices of the elytra are rounded. The legs, except at the base, are blackish, sub-nitid and sparsely setose. The antennae (Q ?) are nearly twice as long as the body, they are covered with a very short pubescence, and the joints are furnished underneath with some very long close-lying hairs ; the third joint is about equal in length to the fourth. Though readily distinguishable from Nericonia trifasciata, Pasc. the above species agrees with it very well in structural characters. The two species placed by Pascoe in Melegena differ by no very strongly marked characters, but may be distinguished by the emarginated and toothed (or spinose) apices of the elytra; and their somewhat less strongly clavate femora. In all of there as in the other members of the group Disteniides there is an oblique groove or notch on the tibiae of the middle pair; and there is also an oblique, though less distinct, groove on the ventral side of the tibiae of the anterior pair similar to that which is so characteristic of the Longicorns of the subfamily Lamiidae. 32 C.

Prothorax above with four indistinct fulvous vittae, two near the middle and one on each side just above the lateral spine. Scutellum pubescent, with a median line naked black and glossy. Elytra punctate, with an ashy-grey pubescence, interrupted by faint irregular brownish patches; each elytron at the base with two short arcuate velvety-black vittae which include some black shining granules, the shoulders also are granulate. The body underneath and the legs have an ashy or fulvous pubescence, which is interrupted by numerous small naked points. The mesosternum is very feebly carinate in the middle. Antennae with a greyish pubescence. This species may be easily recognized by the peculiar eye-like arrangement of spots at the base of each elytron. There is a similar eye-like spot in Morimus? diophthalmus, Pascoe but the latter species is easily to be distinguished by its shorter, more robust, and strongly punctured antennae; by its shorter meta- sternum ; and by many other characters. 80.

I have seen many examples from Assam, and a large series from Mungphu in Sikkim. In the Sumatran exainple, figured by Ritsema, the elytral spots seem to be of rauch less than the average size. The few examples from Burma that I have seen may be regarded as constituting a variety, characterized by the distinct, though by no means strong, tu- berculation of the mesosternum. The elytral spots in this variety form seven irregular transverse series. I have noticed a tendency towards a tuberculation of the mesosternum in some of the North Indian examples; so that I am inclined to believe that we have here a single variable species, rather than two or three distinct, though closely allied, forms. 89.

Long. 15. Lat. 5 mm. Carin Mts. (Cheba district); alt. 900-1100 m. Head with a rather narrow triangular cleft between the an- tennal tubercles; the front sub-rectangular, and almost perfectly . flat; the lower lobes of the eyes rather small, not reaching more than half way to the base of the mandibles. Prothorax with a small conical tubercle, having a broad base, at the middle of each side; dark brown, with the base and two longitudinal vittae on each side above fulvous-pubescent; with a similar fulvous vitta placed very low down on each side. Elytra thickly but not strongly punctured; dark brown, with numerous small pubescent spots of a fulyous colour, which are irregularly scattered, and, in places (especially towards the apex), have a tendency to run together, thus forming small patches.

This species is known also from Japan and China; and from Assam, Nepal and other districts in North India. Hope’s diagnosis of Lamia cervina is too brief to be of the least use in the identification of the species; especially as there are many closely allied and very similar forms. I regret, the- refore, that, in deference to the law of priority, I am obliged to displace the more recent and better known name. In the British Museum collection there are two abnormal examples of this spe- cies, from Hong Kong, in which the antennae are nine-jointed. 91. Haplohammus punctifrons, sp. n.

Long. 15-18 mm. _ Tenasserim: Kawkaret and Meetan; Carin (district of Cheba), alt. 900-1100 m. Closely allied to H. cervinus, Hope, from which it differs by having the scape of the antennae slightly narrower and more cylindrical, and scarcely perceptibly longer ; and the head spar- sely punctured in front, and on that part of the vertex which lies between the antennae and the upper lobes of the eyes. In H. cervinus the head is usually entirely impunctate, though in three or four, out of the many examples that I have seen, there are a few widely dispersed punctures on the front. I have seen only females of the present species; the male will probably be found to have joints 3."7-5." of the antennae thickened as in H. cervinus. LONGICORN COLEOPTERA FROM BURMA 37 92. Haplohammus longiscapus, sp. n.

Long. 18-20 mm. Palon in Pegu: also taken in Tharawaddy by Mr. Corbett. This species closely resembles H. cervinus, Hope, but is to be distinguished by the length of the antennal scape, which is rather more than two-thirds of the length of the third joint. When the antennae are turned back over the sides of the pro- thorax, the scape extends beyond the lateral thoracic spine. In A. cervinus, the scape, when in a similar position, does not reach to the thoracic spine; it is scarcely more than half as long as the third joint. 93. Haplohammus griseipennis, Thoms. Wonochamus griseipennis, Thoms. Archiv. Ent. I, p. 296. Carin Mts. (district of Cheba) alt. 900-1100 m. and Thagata in Tenasserim. Occurs also in North India. This species, though of somewhat smaller size, has the ge- neral aspect of H. cervinus, Hope, and its allies; but it has a distinctly paler pubescence which varies in colour from an almost ashy-grey to a light yellowish-grey; the pronotum and the ely- tra are more minutely and much more closely punctured; and joints 3'-5'» of the male antennae are not sensibly thickened. The front of the head is slightly transverse, and is minutely and somewhat sparsely punctured; the vertex has also a few minute punctures. The scape of the antennae in the male is a little more than half as long as the third joint. The elytra are rounded at the apex. 94. Haplohammus basicornis, sp. n. Pube griseo-brunnea dense obtectus; capite prothoraceque impunctatis, hoc antice obsolete sulcato, et ad basin recte bisulcato: elytris versus basin sat sparsim punc- tulato, apicibus rotundatis; antennis (7) quam corpore fere triplo longioribus, scapo brevi usque ad apicem valde incrassato, articu- lis 3° ad 5°™ haud incrassatis. Long. 20 mm. 38 C. J. GAHAN Carin Mts. (district of Ghecu) at an altitude of from 1300- 1400 m. This species somewhat resembles H. cervinus, Hope, but may distinguished by the form of the antennal scape, which is strongly thickened to the apex, and by the absence of any evident thickening of the third, fourth and fifth joints. The joints of the antennae from the third are testaceous in colour with a slight infuscation at the tips. The pubescence, which in the present condition of the type specimen is dull, would probably in the fresh state exhibit a silky or satiny lustre. 95. Haplohammus admixtus, sp. n. Parvus, pube griseo-brunnea sat dense obtectus; capitis fronte vir punctata, sat angusta, quam latitudine distincte altiort, twberculis antenniferis anguste separatis ; prothorace supra sparsim puncetato; scutello cinereo: elytris sat dense punctatis, griseo-brunneo-pubescentibus, versus medium spar- sim trregulariterque fusco—-maculatis; antennis (“) quam corpore triplo longioribus, scapo brevi obconico, apice late cicatricoso, arti- culo tertio quam scapo plus duplo longiort, haud incrassato. Long. 11-14 mm. Carin Mts. (district of Cheba), alt. 900-1100 m. This species is to be distinguished from the preceding by the less uniform pubescence of its elytra, the general greyish-brown tint of which is diversified by some irregular spots and points of a somewhat dark-brown colour; and, more particularly, by the narrowness of the front of its head. The scape of the an- tennae is rather short and obconical, with a broad and distinct but incompletely margined cicatrix at the apex; the third and following joints are slender, the third is more than twice as long as the scape, the fourth is manifestly, the fifth scarcely, shorter than the third. 96.

The species occurs also in Assam, in Siam and in China. The genus, to which it belongs, was first characterized by LONGICORN COLEOPTERA FROM BURMA 39 Guérin-Méneville (Voy. Delessert, Vol. II (1843), p. 59), who proposed for it the name Macrochenus, Pascoe subsequently (Proc. Zool. Soc. 1866, p. 252) described it under the name of Mecotagus, by which it has since been generally known. WM. tes- sellatus, Guér. (1. ¢.), the type of the genus, is probably iden- tical with, or, at most, a variety of MW. tgrinus, Oliv. 97. Melanauster zonator, Thoms. — Cyriocrates zonator, Thoms. Rev. et Mag. de Zoologie, 1878, p. 50. — Melanauster zonator, Ritsema, Notes from the Leyden Museum, Vol. XII, p. 180. One example taken at Carin Mts. (district of Ghecu) at an altitude between 1300 and 1400 metres. The species occurs also in Siam. The pale green scaly pubescence of the elytra in this example, instead of being arranged in regular transverse bands, as in the type (with which, through M. René Oberthir’s kindness , I have been enabled to compare it) is broken up into spots, of which the first series consists of three, oblong or quadrate, near the base of each elytron, the second of two on each ely- tron — one, smaller, lateral, the other larger and transverse, near the suture; the third row is made up of one large transverse spot towards the side of each elytron, and of two smaller spots on the left elytron and one on the right elytron, near the suture; the fourth row consists of two spots on each elytron — one, large, transverse, towards the sides, one, smaller, close to the suture. This row is succeeded by a large spot at the apex of each elytron. In its remaining characters the specimen agrees well with the type. There is an example from Siam in the British Museum col- lection, in which the third and fourth bands of the right ely- tron are broken into spots near the suture, and exhibit a want of symmetry in relation to the bands of the left elytron. It is probable, therefore, that a considerable amount of individual variation exists with regard to the arrangement of the pube- scence in this species. 98. Melanauster Medenbachii, Ritsema. Notes from the Leyden Museum, Vol. III, p. 39 and Vol. XII, p. 180. 4U : Cc. J. GAHAN I have no hesitation in referring to this species two fine male examples which were taken at Thagata in Tenasserim. The pubescent bands of the elytra in these examples are of a beautiful golden green colour. Mr. Ritsema’s supposition that the grey colour of the pubescence in his specimen was « due to their having been preserved for some time in spirits » is thus shown to be correct. The characters by which the species has been stated to differ from M. zonator are clearly evidenced in the two examples before me. 99. Melanauster chinensis, Forst. — Cerambyx chinensis, Forst.

A. reticulatori semdlis et affinis, sed differt articulis antennarum quarto quintoque apice haud villosis. Taken on the Catcin Mts.; at Carin Mts. (district of Asciuii Cheba) at an altitude of 1200-1300 m., at Rangoon in Lower Burma, and at Bhamo in Upper Burma. This species is allied to, and closely resembles, A. reticulator, Fabr. It has, however, somewhat smaller ochreous spots on the elytra and differs, especially, by the complete absence of tufts of black hairs from the fourth and fifth joints of the antennae. The third joint only is furnished with a thick tuft of black hairs. The species resembles A. clathrator, Thoms. in the smaller size of the ochreous spots of the elytra. I have seen a considerable number of examples of this species from Burma, and in all, without exception, the fourth and fifth joints of the antennae have the characters mentioned above. 101.

René Oberthiir, during a visit to Lon- don, recognized Thomson’s species in my type. All the exam- LONGICORN COLEOPTERA FROM BURMA 4] ples I have seen have a pale grey or ashy-grey pubescence , not a yellowish pubescence, as in the specimens described by Thomson. In his description also the prothorax is said to have some yellow spots above, but I think I have more correctly described it as grey (or yellowish) with numerous small black spots above. The difference in coloration is doubtless to be attri- buted, as M. Oberthiir suggests, to the action of the spirit in which some of the specimens were preserved. 102.

Long. 18-20 mm. Taken at the Carin Mts. (district of Cheba), at an altitude of 900-1100 m. Head and prothorax with a rather thin greyish pubescence. Prothorax with numerous rather closely placed black granules which extend over almost the whole upper surface except the anterior and posterior borders. Elytra closely and rather strongly punctured at the base and along the middle, the punctures dis- 42 Cc. J. GAHAN appearing posteriorly: each with a somewhat roughly triangular velvety brown patch at the side just behind the middle; this patch bounded in front and behind by an oblique dirty white patch which appears to be almost impunctate. The whole fore- part of the elytra extending triangularly backwards between the lateral plagae is dark brown in colour, and is clothed with a faint greyish pubescence, with, here and there, a sprinkling of fulvous. The posterior part of the elytra has a greyish pu- bescence irregularly speckled with brown. The body underneath and the legs have a greyish pubescence, with minute rounded naked points wich appear reddish brown or dark brown accord ing to the colour of the derm. The mesosternal process is dis- tinctly, though not strongly, tubercled in the middle. This species is somewhat closely allied to U. angusta, Pascoe, but in the latter the velvety-brown lateral patch of the elytra is slightly darker in colour, is obliquely placed, and has a distinctly, though sparsely, punctured patch clothed with pale greyish or cinereous pubescence, both in front of and behind it. The anterior part of the elytra is as thickly covered with pube- scence as the rest of the surface, so that the derm of that part is almost completely concealed. The mesosternum is very faintly or not at all, tubercled. 106. Uraecha thoracica, sp. n. Elongata, modice angustata, pube albo-cinerea, brunnea et fulva vestita: prothoracis disco area sub- cordata paullo elevata, cujus apice scutellum fere attingente, antice leviter bituberculata, et medio utrinque nigro-granulosa, prothoracis lateribus sat valde spinosis, et ante spinam tuberculo parvo munitis; scutello albo-cinereo; elytris versus basin subasperato sat fortiterque puncetatis, punctis versus apicem evanescentibus; apicibus sub-trun- catis, fere rotundatis, corpore subtus pedibusque brunnescentibus vel obscure grisescentibus, maculis episternorum abdominisque et annulis angustis femorum albescentibus, exceplis. Long. 14-20 mm. Taken at Carin Mts. (districts of Cheba and Ghecu), altitude 900-1400 m. and also at Plapoo in Tenasserim. Head dull greyish or brownish in front, pale fulvous around the eyes and on the occiput, with a median impressed black LONGICORN COLEOPTERA FROM BURMA 43 line extending from the epistome to the thorax, with two short oblique black lines on the vertex, each commencing at, and appearing as a continuation of, the upper lobe of the eye. Prothorax furnished at the middle of each side with a tolerably strong spine, and just in front of the spine with a small tubercle; the disk exhibiting a slightly raised area, somewhat cordate in shape, of which the obtuse apex almost touches the scutellum, and at the anterior extremity of which there is on each side a very small tubercle; along each side of the middle line there are some closely placed black granules (which in the largest specimen appear as two distinct black patches), and there are a few scattered granules extending on to the lateral part of the disk and around the base of the lateral spine and tubercle; the pubescence of the prothorax is partly pale fulvous (chiefly on the raised central area) but mostly dull greyish, with a very small blackish spot surrounded by a whitish patch placed on the side anterior to, and just above, the angle of the cotyloid eavity. The scutellum is whitish, with a very small black point in front. The elytra are somewhat asperately, but not densely punctured at the base; the punctures, becoming gradually feebler posteriorly, entirely disappear at about the beginning of the apical fourth. The velvety brown pubescence of the elytra is limited to a larger irregular and somewhat broken patch occu- pying the middle of the basal fourth, and to three, or more, patches on each side, of which the one the nearest the middle is much larger than the rest. The body underneath and the legs vary from greyish-brown to brown, with a distinct spot on each of the meso- and meta-thoracic epimera, some small obscure spots on the abdomen, and a narrow sinuous ring near the apex of each of the femora, whitish. The antennae, more than twice as long as the body in the male, and half as long again as the body in the female, are brownish, with a fulvous spot near the outer extremity of the scape, and a dull greyish ring at the base of the third and following joints. The meso- sternum is very feebly tubercled between the middle coxae. 44 Cc. J. GAHAN 107. Blepephaeus succinctor, Chevr. — Monohammus succinctor, Chevr.

Long. 18-20. Lat. 51/,-6 mm. Tenasserim, Thagata and Meetan. Head impunctate, with a brownish pubescence; the lower lobes of the eyes large and somewhat rounded, reaching below almost to the base of the mandibles. Scape of the antennae rather long and cylindrical, equal in length to two thirds of the third joint; eleventh joint a little longer than the tenth. Prothorax with a thick brownish pubescence, sparsely punctured above and with two very feeble tubercles on each side above; scutellum cervi- nous. Elytra with a light brown or fawn-coloured pubescence, with the base and a somewhat triangular patch on each side behind the middle infuscate, with minute rounded fuscous spots which are sparsely scattered, and in the centre of each of which there is a rather large puncture. The apices of the elytra are truncate. The middle tibiae are without groove or tubercle. The mesosternum is feebly tubercled between the middle coxae. This species, which is smaller and narrower than Blepephaeus succinctor, Chevr. appears to be nearly allied to Blepephaeus sub- cruciatus, White (Monohammus) and still more closely to an un- described form from North India. 109. Eutaenia Oberthuri, sp. n. Cinereo-pubescens; prothoracis fascia transversa media, elytrorumque fasciis tribus communibus et macula rotunda utrinque ante apicem nigris; antennis (2) quam corpore paullo longioribus, nigris, articulis 3°-7° basi cinereis. Long. 21-23 mm. ilk LONGICORN COLEOPTERA FROM BURMA 45 Carin Mts. (district of Cheba), alt. 900-1100 metres. Cinereous; with a transverse black band on the prothorax which extends over, and embraces, the tubercle on each side, with three somewhat irregularly formed transverse black bands on the elytra and a rounded spot of the same colour on each a little before the apex. The female antennae surpass the apex of the elytra by about the last three or four joints; joints 3-5 are subequal in length, and each is longer than the sixth or seventh; joints 8-10 are also subequal, and each much shorter than the seventh; the eleventh is scarcely longer than the tenth. The last abdominal ventral segment of the female presents a most unusual character. This segment is rather broadly emar- ’ ginated at the apex, the emargination being limited on each side by a short blunt tooth; at a short distance in front of the apical margin there projects from the ventral surface a lamellar process, bidentate at its free extremity, with a narrow angular emargination between the teeth; a narrow transverse depression somewhat wider in the middle, is enclosed between this process and the downwardly curved apical portion of the segment, and is thickly lined with fulvous hairs, the arrangement being such that the depression itself might readily be mistaken for the terminal opening. An exactly similar structure exists in the females of Eutaenia trifasciella, White — the type of the genus. The latter species differs from the one above described by hav- ing distinctly shorter antennae (in the female at least), by the tawny-yellow colour of its pubescence, and its narrower black bands. Eutaeniopsis, Gahan, is a synonym of Eutaenia, Thoms. Thomson’s characterization of the genus is brief and somewhat inaccurate. I have seen his type, through the kindness of M. René Oberthiir, to whom I am happy to dedicate the new species. 110. Cycos subgemmatus, Thoms. — Monochamus subgemmatus, Thoms., Archiv. Ent., I, p. 294. — Monochamus georgius, White, Proc.

Pharsalia antennata, sp. n. Fusca, prothorace supra lineis quatuor fulvis ; elytris maculis paucis atro-velutinis et maculis mi- nutis fulvis sub-confluentibus et irregulariter dispersis; capite tu- berculis antenniferis contiguis; elytris valde punctatis obtuse cari- natis, utrisque ad basin tuberculo magno munitis ; apicibus rotun- datis; antennis quam corpore multo longioribus, rufo-ferruginets, articulorum apicibus fuscis: articulis 3° et 4° () apice imerassalis articulis 3° et 4° (Q) apice nodosis. Long. 20-25 mm. Upper Burma (Catcin Cauri) one # example, and Carin (district of Cheba) one 9 example. Dark brown, prothorax with four fulvous lines above; elytra with some velvety black spots and with numerous minute ful- vous and grey spots which here and there run together. Head with the inner horns of the strong and vertical antennal tuber- cles meeting in the middle line, and leaying a slight depression between them only on the anterior face. Prothorax slightly rugose above, and with a sharp conical tubercle on each side. Elytra rather coarsely punctured, especially towards the base, strongly nitid where not covered with pubescence, each with two or three obtuse carinae, and furnished with a strong tu- bercle, whose anterior face rises sub-vertically from the basal margin; apices of the elytra rounded. Body underneath with minute scattered fulvous spots. Legs reddish brown with faint grey pubescence. Antennae in the female more than half as long again as the body (the antennae in the single male example are broken off from the seventh joint), with the third and fourth joints in the female nodose at the apex, with the same joints in the male thickened, but not nearly so strongly as in the female; the scape is ferruginous brown, the remaining joints reddish brown with their apices fuscous. The exceptional characters of this species will enable it to be readily recognized. Notwithstanding the close contact of its an- tennal tubercles, and the decided thickening of the apices of LONGICORN COLEOPTERA FROM BURMA 47 the third and fourth joints of the antennae, I do not see that the species can be better placed than in Pharsalia. 112.

The species occurs also in North India (Sylhet, Darjeeling , and Nepal). 121. Himantocera vicina, sp. n. H. penicillatae persimilis sed differt articulo antennarum quarto inter medium apicemque non constricto, et articulis 8° ad 10°™ apice haud fasciculato—pilosis. Carin (districts of Cheba and Ghecu), alt. 900-1500 m. This species so closely resembles H. penicillata, Hope, in size, general form and style of coloration, that only the points of difference need be stated. The fourth joint of the antennae is 48 Cc. J. GAHAN gradually thickened from before the middle up to the apex; ‘the joints succeeding the fourth are all in both sexes destitute of small tufts of hairs, and, with the exception of the fifth, have an uniform fulvous-grey pubescence. This last character, however, though holding good for the few specimens from the Carin Mts. which I have seen, is liable, I think, to variation and may be considered of very little importance. In H. penicillata, Hope, the fourth joint of the antennae is thickened at the middle, and, between this thickening and the large swelling at the apex, is somewhat narrowed or constricted ; in the males of this species a small but distinct tuft of black hairs is to be seen on the underside at the apex of each of the joints from the eigth to the tenth; a few black hairs of similar character.are to be found in fresh specimens at the apex of the seventh and at the middle of the eleventh joint. In specimens from Java and Borneo which I refer to H. plu- mosa, Oliv., the fourth antennal joint has a form similar to that of H. penicillata, but the succeeding joints are in both sexes destitute of small pencils of hairs. In these specimens also the disk of the prothorax is a little less uneven than in H. penicil- lata or H. vicina. So far as the relative length of the prothorax is concerned I am unable to detect any appreciable differences in the three species just mentioned. What Lacordaire regarded as a specific distinction seems to me to be simply a sexual difference. In the males of all the species the prothorax is decidedly longer than in the females. 122. Golsinda basicornis, sp. n. G. corallinae persimilis sed minor, magis parallela, scapo antennarum apice minus abrupte incrassato, quam articulo tertio paullo breviore. Long. 14-22 mm. Carin (district of Ghecu), alt. 1300-1400 m.; also Siam, Laos, and Allahabad (British Museum collection). This species strongly resembles Go/sinda corallina, Thoms. with which it seems to have been confounded by Mr. Pascoe (vide Longic. Malay. p. 133) as it was by myself until a recent examination had shown me that the specimens from Laos and LONGICORN COLEOPTERA FROM BURMA 49 Siam are specifically distinct from those from Borneo. The elytra in the new species are more parallelsided, the scape of the an- tennae is less elongated, and less abruptly thickened at the apex, is rather shorter than the third joint, and carries a reddish pubescent patch near the middle. In corallina the elytra are considerably narrowed from the base backwards, the scape of the antennae is rather abruptly thickened at the apex, is slightly longer than the third joint and has not a reddish patch. 123. Mesosa (') subfasciata, sp. n. Pube fulvo-brunnea grisea- que, fusco-maculata, obtecta; elytris fascia transversa media, lata sed irregulariter marginata, pallidiore, ante hanc fasciam fere totis fuscis; apicibus anguste rotundatis ; antennis fuscis, scapo griseo, articulis 3°-et sequentibus bast cinereis. Long. 11-15 mm. Carin. Mts. (district of Cheba), alt. 900-1100 m. This species has the head slightly less concave, the prothorax more rounded at the sides, and the elytra more attenuate posteriorly than in Mesosa nebulosa, Fabr., but otherwise agrees with it fairly well in structural characters. The antennae of the male are more than half as long again as the body. In this sex also there is a narrow transverse pilose depression towards each side of the anterior border of each of the three intermediate abdominal sternites. Each depression is concealed more or less by a fringe of fulvous hairs attached to the hind margin of the sternite immediately in front. The antennae of the female reach to a little beyond the apex of the elytra. 124. Mesosa obscura, sp. n. Griseo et fulvo-griseo pubescens; punetis maculisque fusco-brunneis; capite inter antennas sat fortiter concavo; prothorace supra leviter trituberculato, basi apiceque recte lineato-sulcato et paullo pone apicem sinuato-impresso, laterihus leviter inaequalibus et obsolete rugosis, elytris punctatis, fulvo-griseo- pubescentibus, maculis punctisque fusco-brunneis, corpore subtus () The genus Mesosa was first characterized by Latreille (Régne Animal, 2 de Edit. Tom. V, p. 124); though Serville is usually cited as its author. Aplocnemia, Ste— phens (Illustrations of Brit. Ent. 1V (1831) p. 236), which is a synonym of Mesosa, was not described until two years later. C. J. GAHAN. 4 50 C. J. GAHAN pedibusque griseis, femoribus medio tibiisque- basi et apice fusco- maculatis; antennis griseis, articulis apice fuscis. Long. 12-15 mm. Bhamo in Upper Burma. Two examples. Head strongly enough concave between the antennal tuber- cles, minutely and rather sparingly punctured in front, feebly impressed along the middle line. Prothorax rather narrow, with three feeble tubercles on the disk, of which the third and smallest is placed near the base (this tubercle is, in the larger of the two specimens before me, divided in the middle by a narrow groove); the sides are made slightly uneven by the presence on each of two very feeble and obtuse tubercles — one a little behind the anterior margin, the other much farther back and a little higher up; between these tubercles and ex- tending upwards on to the disk are some feeble transverse rid- ges (not evident in the smaller specimen). Scutellum dark brown with a grey centre. Elytra strongly enough and rather closely punctured, the sides nearly parallel; pubescence grey with ir- regularly scattered small fuscous spots and points. Antennae (“) about one half longer than the body: the first two joints grey, the remaining joints grey at their bases only; first joint not much more than half as long as the third joint; the latter longer than the fourth; the eleventh joint with a short hooked appendix. Intermediate segments of the abdomen with narrow, transverse, pilose depressions placed anteriorly towards each side. In this species some of the characters of Coplops are united with those of Mesosa; but they point on the whole to its po- sition in the latter genus. 125. Cacia ornata, sp. n.

Long. 15 mm. Two examples; one taken at Palon in Pegu, the other at Carin (Cheba). Pubescence greyish, somewhat paler on the underside of the body. Head with a median impressed glabrous black line; with two velvety black lines which extend from the thorax down- wards between the antennary tubercles, slightly diverging in their course, and becoming obliterated on the front of the head; with a short velvety black vitta on each side above behind the upper lobe of the eye. Prothorax somewhat sparsely punctured above, with a median dorsal fuscous vitta, and with two velvety black spots, narrowly margined with cinereous, which are placed one on either side of the anterior part of the disk; with a small longitudinal black spot placed somewhat anteriorly and low _down on each side. Scutellum fuscous. Elytra strongly enough, but not very thickly punctured, adorned with numerous lines and about eight small spots of a velvety black colour, and with five white spots. Of the black spots three are placed along each outer margin, and two posteriorly on the suture. Of the white spots, one is placed somewhat dorsally on each elytron a little in front of the middle, another smaller and less distinct behind the middle, while the fifth is on the suture and just in front ‘of the anterior of the two sutural black spots. Legs and under- side of body grey, with some fuscous points and spots; abdo- minal segments fringed with pale fulvous-grey posteriorly. Pro- sternal process strongly arched, declivous behind; mesosternal process vertical in front, feebly tubercled near the lower ante- rior border. Antennae (o”) about one half longer than the body, ciliate underneath, the ciliae being more densely aggregated and blackish in colour beneath the fifth and the apex of the third joint. This rather pretty species may be easily recognized by its peculiar markings which I have described above in some detail. 126. Cacia cretifera, Hope. — Lamia cretifera, Hope, in Gray’s Zool. Misc.

Griseo-pubescens, capite prothoraceque nigro-vitlatis, elylris nigro maculatis et punctatis; antennis nigris articulis 3° ad 6"™ basi cinereis; pedibus nigro annulatis et punctatis; prothoracis lateribus antice obsolete tubercu- latis ; mesosterno antice verticali et leviter tuberculato; prosterno postice verticali; articulo tertio antennarum quam primo paullo longiort. Long. 16. Lat. 7 mm. Malewoon in Tenasserim. One example. With a vellowish-grey pubescence. Head impunctate, feebly concave between the antennal tubercles, with two longitudinal black vittae extending almost from the labrum in front to the occiput behind, and with a short black vitta or spot behind the upper lobe of each eye. Prothorax slightly rounded at the sides, each of which bears a small and-almost obsolete tubercle placed a little behind the front margin; with two black vittae on each side, one broad placed low down, the other, very much narrower and almost lineate, placed higher up towards the disk, the disk also with a black vitta on each side and with three somewhat glabrous spots surrounding the middle, the posterior of which appears very slightly elevated and divided by a feeble median impressed line. A few black punctures are scattered through the fulvous-grey bands which occupy the intervals be- tween the black vittae. The scutellum is black, with a grey spot in the middle, and is surrounded by a somewhat rectangular black spot common to the two elytra; another common oblong spot is placed on the elytra just before the middle, while on each elytron there are about eight other somewhat similar but more irregular spots, of which the largest lies at, and below the shoulder, the elytra bear in addition some scattered black points in the centre of each of which lies a puncture. The body underneath has a yellowish-grey pubescence interrupted by black spots and points. Legs grey, with black small rounded points on the femora, a ring at the apex of each femur and two on LONGICORN COLEOPTERA FROM BURMA 53 each tibia black. Antennae (7) about half as long again as the body, shortly and thickly ciliate below, black, with the scape slightly, the bases of the joints from the third to the sixth, and the tip of the last joint pale grey; third joint slightly longer than the first or fourth. 128. Agelasta mixta, sp. 1. Brunnescente-pubescens, capite pro- thoraceque nigro-vittatis; elytris nigro cinereoque maculatis et nigro- punctatis, punctis praecipue versus basin in seriebus longitudinalibus aggregatis, corpore subtus pedibusque fulvo-brunneo-pubescentibus, femoribus sparsim nigro-punctatis, tbiis apice nigris; anlennis griseo-brunnescentibus, articulis 3° ad 6"™ apice, et 7° ad 10"™ totis nigro-fuscis. Long. 17-18 mm. Carin Mts. (Cheba district). Prothorax with two feeble nearly obsolete tubercles on each side, one at the middle, the other a little behind the anterior margin. Third joint of the antennae distinctly longer than the first or fourth. Prosternal process strongly enough arched and rounded in the middle, vertical behind. Mesosternal process vertical in front, horizontal below, feebly tubercled at its antero- inferior edge. This species seems nearly enough allied to the preceding, but may be easily distinguished by the general brownish tone of colour of its pubescence, the fewer black spots on the elytra, and the presence of three ashy spots along the suture and some scattered spots on each elytron. The black bands of the head and prothorax are disposed in very much the same manner as in C. nigromaculata, the black points on the elytra are more numerous, and arranged, especially towards the base, in some- what irregular longitudinal series. The two species just described agree with A. transversa, Newm. — the type of the genus — in the relative proportions of the joints of the antennae, in the shape and tuberculation of the prothorax, and of the pro-and mesosternal processes; they agree, in fact, in all essential points of structure. Their relatively nar- rower elytra, however, give them an appearance more resem- bling the species of Copfops; but from the more typical species 54 Cc. J. GAHAN of the latter genus they are be distinguished by the absence of a distinct antero-lateral tooth or tubercle from the prothorax, by having the posterior face of the prosternal process vertical, and the third joint of the antennae longer than the first or fourth. In the males each of the three intermediate ventral seg- ments of the abdomen has on each side anteriorly a narrow transverse depression which is more or less concealed by the fringe of hairs attached to the hind margin of the immediately preceding segment. This character is not present in the males of the typical species of Coptops, nor, with the exception of A. tran- sversa, Newm., A. bifasciana, White, and possibly a few others, does it exist in those species hitherto included in Agelasta. 129. Coptops annulipes, sp. n. C. fuscae sat similis et affinis, sed differt pube rufo-mixta; prothoracis dorso distinctius fusco- bivittato, lateribus utrisque vitla nigro-fusca, distincta, paullo supra coram posita; elytris utringue medio plaga obliqua, pallide grise- scenle plus minusve distincta; pedibus nigro-fusco distincle annu- latis. Long. 14-20 mm. Carin Mts. (district of Cheba), alt. 900-1100 m. The British Museum collection contains examples from Siam, Cambodia, Burma, and North India. This species is closely allied to Coptops fusca, Oliv., of which it may possibly be only a well marked variety. The pubescence has usually a considerable admixture of red. The head has two dark-brown yittae above; there are two dark-brown vittae also on the disk of the prothorax, while on each side, just above the coxa, there is another very distinct blackish brown vitta which does not quite reach to the anterior or posterior margin. The elytra are marked with spots and points of dark-brown ; while a pale ashy-grey pubescence, slightly. mixed with red, forms a more or less distinct and broad, oblique fascia across each elytron near the middle, and extends forwards for some distance in the sutural region. The same characters that serve to distinguish this species from C. fusca will distinguish it also from Coptops aedificator, Fabr. The two latter in fact are scar- cely distinct. LONGICORN COLEOPTERA FROM BURMA Hays) Coptops aedificator, Fabr. is sometimes known under the name of bidens, Fabr., with which it is placed as a synonym in the Catalogue of Gemminger & Harold. But the characters of Lamia bidens, Fabr. — « thorace acute-spinoso. Elytris apice bidentatis » — show that this species does not even belong to the genus Coptops. The mistake probably arose from the fact that a spe- cimen of C. aedificator in the Banksian Cabinet is erroneously ticketed Lamia bidens, Fabr. To this specimen there is an addi- tional label attached, bearing the words « an bidens Fabricii? ». The actual type of the species appears to have been lost. 130. Coptops Pascoei, sp. n. Brunneo-griseo-pubescens, punctis maculisque fuscis; capitis fronte infuscata; prothorace supra medio leviter tri-tuberculato, lateraliter utrinque vitta lata fusco-velutina; scutello medio griseo, lateribus fuscis; elytris punctis maculisque fuscis, his fascias irregulares duas, vel tres formantibus; corpore sublus grisco sparsim fusco-punctato,; pedibus griseis, fusco-annulatis; antennis articulis 2° et 3° fere totis, ceterisque apice infuscatis. Long. 11-17 mm. Bhamo in Upper Burma (Fea); Siam, Cambodia, (in coll. Brit. Museum). Pubescence greyish, varying, especially on parts of the elytra, to a pale brown. Head somewhat dark-brown in front. Prothorax grey to greyish-brown, with a broad, dark-brown, velvety band on each side extending from the anterior to the posterior margin, and with its upper and lower margins somewhat irregular, the disk with three feeble tubercles, the sides each with a small tubercle placed a little behind the anterior margin and at the ‘upper border of the fuscous.band, with a second, somewhat larger, but more obtuse, tubercle a little ‘higher up and nearer the middle line. Scutellum grey, bordered at the sides with fuscous. Elytra punctured, each with a very small tubercle near the middle of the basal margin, and with an obtuse prominence a little farther back, pubescence grey and pale brown with scattered points, and irregular spots, the latter aggregated to form indefinite dark-brown bands, of which one is just behind the basal prominences, and is followed by an isolated spot on 56 Cc. J. GAHAN each elytron, the second is a little behind the middle, while a third very indistinct band is placed a little before the apex. This species, which is allied to, and somewhat closely resem- bles Coptops aedificator, Fabr., C. fusca, Fabr., and other species, may yet be sufficiently distinguished by the broad and distinct dark-brown band on each side of the prothorax, taken together with the other characters detailed aboye. I have named it in memory of Mr. Pascoe to whose labours we are indebted for the descriptions of most of the known species of this difficult group. The species has hitherto been known only from Siam and Cambodia. 131. Coptops vomicosa, Pasc., Journ. of Ent., I, 1862, p. 341. Carin Mts., Cheba district, 900-1000 m. Mesolophus, g. np. Head strongly enough concave between the antennal tuber- cles. Eyes sub-divided. Antennae (Q) longer than the body; the scape elongate, a little shorter than the third joint; the latter slightly curved, longer than the fourth, the following joints gradually decreasing in length. Prothorax transverse, unarmed at the sides. Elytra moderately long, subacute and minutely tubercled at the shoulders, from thence narrowed posteriorly; apices broadly and somewhat obliquely truncate, with the outer angles obtusely rounded off; each elytron with a short pro- minent crest placed a short distance back from the middle of the base. Prosternal process with its posterior face vertical, its postero-inferior edge, which is somewhat obtusely pointed in the middle , projecting slightly backwards; the mesosternal process is strongly declivous or almost vertical in front, its ventral face is very short amd is slightly raised along the middle. The legs of the female are sub-equal in length; the intermediate tibiae entire; the claws of the tarsi divergent. This new genus of the Mesosides resembles Aesop/da in having a basal crest on each of the elytra, but this crest does not LONGICORN COLEOPTERA FROM BURMA 77 reach as far as the anterior margin; it is distinguished further from Aesopida by the rather acute shoulders of its elytra, and by the absence of tubercles or teeth from the sides of the pro- thorax. 132. Mesolophus humeralis, sp. n. (Pl. I, fig. 10). Niger, pube fulvo-brunnea, fasciis maculisque atro-velutinis ornalus, antennis nigris, articulis 1° 2°que brunnescentibus, ceteris basi cinereis. Long. 16 mm. Carin Mts. (Cheba district), alt. 900-1100 m. One example. With a fulvous brown pubescence, here and there interrupted by cinereous and fuscous spots. Head with two oblong fuscous spots above. Prothorax slightly uneven on the posterior part of the disk, with two somewhat interrupted velvety black vittae, one towards each side of the disk, above. Elytra each with two zig-zag velvety black bands, of which the first, somewhat broader, extends from the basal crest to reach the outer margin a little farther back, the second, a little behind the middle, passes from the outer margin to join the suture, where it forms, with its fellow of the opposite side, an oblong spot lying behind the fascia. Between the second band and the apex there are on each elytron two distinct fuscous or black spots, placed obliquely, the outer being slightly posterior to the inner. In addition to these more definite bands and spots there are some smaller fuscous spots and points, and a few cinereous spots on the elytra. The body underneath and legs have a fulvous brown pubescence ; the former is somewhat spotted, and the latter ringed, or spotted, with fuscous. 133. Aesopida malasiaca, Thoms., Syst.

Upper Burma (Bhamo) and Carin (district of Cheba), alti- tude 600-800 m. The males of this species possess a secondary sexual cha- racter which I have not seen noticed in any description of the species. This consists of a large transverse oval depression on each side of the third, fourth and fifth abdominal segments. Each of the depressions is lined with rather long hairs. 137. loesse sanguinolenta, Thoms. Syst. Ceramb., p. 68; La- cord. Genera des Coleopt., IX, p. 449. Two examples (.7 and 9) were taken by Mr. Fea at Carin Mts. (Ghecu district); alt. 1300-1400 m. Lacordaire in his characterization of this genus has given a very erroneous description of the antennae. With the exception of the first joint, which has a cinnabar- red pubescence, like the head, thorax, &c., the antennae are closely covered with a short dull-black pubescence, and the joints from the third to the sixth or seventh have a short fringe of black hairs underneath. In the male (hitherto undescribed) the antennae reach to about the apex of the elytra, in the female they scar- cely surpass the middle of the elytra. In neither sex do they bear the elongate fossae which Lacordaire specially mentions; nor have they any punctures beyond the extremely minute pits from which the hairs of the pubescence spring, and which only become visible when the latter is rubbed off. The male differs also from the female in having a rather wide angulate emargina- tion at the apex of the last abdominal ventral segment. As La- cordaire’s description of the female agreed so well in every other respect with the female specimen before me, I was unable to account for the remarkable discrepancy in the characters of the antennae. Mr. René Oberthiir, by very kindly sending me the specimen which he believed to be the original of Lacordaire’s description, has enabled me to explain the anomaly. In this LONGICORN COLEOPTERA FROM BURMA 59 specimen three joints only of the antennae — the two first on one side, and one on the other — belong to the insect; the remaining and chief parts of the antennae were very neatly fastened on to these basal joints, and were probably originally taken from a female specimen of Morimus funereus, Muls. The antennae thus manipulated, looked extremely like the true an- tennae, and might readily deceive one who was not examining them especially in order to detect something wrong. It is cu- rious, nevertheless, that Lacordaire, though calling special atten- tion to the character of the antennae in this genus, has alto- gether omitted to notice the same character when treating of the genus Morimus. 138.

Long. 20. Lat. 6.5 mm. Metanja on the Catcin-Hills, Upper Burma. One 9 example. The unique example of this species resembles a very large specimen of R. pubera, Thoms. The colour and disposition of the pubescence are almost exactly the same; the chief difference in this respect being in the relative width and distinctness of the fulvous-grey and fuscous vittae of the prothorax; in pubera the pale vittae are much narrower than the dark ones, and are well defined; in the present species the dark bands are narrower, and all are ill defined; the median fulvous-grey vitta is marked in the middle by a small glabrous black spot. The disk of the prothorax is much less thickly punctured than in pubera and bears a very feeble tubercle on each side just behind the anterior transverse groove. The lateral tooth at the middle of each side is more distinct than in pubera. The apex of the antennal scape has a somewhat rounded cicatrice; but this cicatrice is not, as in the Monohammides, limited by a distinct carina. Notwith- 60 C. J.

Long. 22- 23 mm. Upper Burma, Bhamo. This species may be distinguished from M. thoracica, White LONGICORN COLEOPTERA FROM BURMA 61 by its larger eyes, and the consequent narrower front of its head, the more obtuse and somewhat flattened tubercle on each side of the disk of the prothorax; by the small unfasciculated tubercle placed in the supra-humeral depression at the base of each elytron; and by its generally darker coloration. 146.

The example taken belongs to a variety characterized by having a rather large whitish plaga, placed before the middle on the side of each elytron. In the examples of this species in the British Museum collection which have been brought from Cambodia, there is in a similar position, an indistinct plaga formed of coalesced spots or small patches of a rust colour like that of the general pubescence. The males of this species are provided with a distinct tooth on the ventral side of the anterior tibiae a little below the middle of their length, and also with a small tubercle or tooth at about the middle of the dorsal border of the anterior femora. The females sometimes exhibit a trace of a tooth on the anterior tibiae in a similar position to that of the male. The last ventral segment of the abdomen has almost exactly the same form in both sexes, but in the female is impressed along the middle, with a feeble groove. There is a more distinct fringe of fulvous hairs, attached to the hind margin of the first abdominal seg- ment in the male: towards the sides this fringe conceals a very narrow transverse depression or declivity at the anterior margin of the succeeding segment; but there is on the segment no distinct semi-oval and piligerous depression as in N. picticornis, Muls. and certain other species. The anterior tarsi of the males do not seem to be appreciably more dilated than those of the females. 62 C. J. GAHAN 148. Niphona vicina, sp. n. N. furcatae (Bates) persimilis et affinis, sed elytrorum apicibus minus obliquiter truncatis. Long. 15-16 mm. Thagata in Tenasserim. Two examples. Clothed with a pubescence which is mostly of a yellowish or ochreous-grey colour, but which is ashy-white on the inner side of the legs, along the middle of the underside of the body, and on the sides of the elytra. Head with the lower lobes of the eyes moderately large, the vertex forming with the front an almost continuous curve. Prothorax very slightly rounded and unarmed at the sides; the disk longitudinally ridged in the middle, with, usually, three of the ridges regular and distinct, while those external to them are broken and irregular, so that the outer part of the disk and the sides of the prothorax have a somewhat roughly granular appearance; the anterior part (almost a third) of the disk is smooth; while at the base there is a fine transverse groove, followed in the middle by a slight posterior lobe which fits closely against the scutellum. The ely- tra, broadest at the base, gradually narrow up to the beginning of the apical fourth, and thence are more strongly attenuated to the apex; the apical truncation of each elytron is somewhat oblique with a slight emargination close to the suture; the out- line of this margin is more or less obscured by a fringe of hairs; the punctuation of the elytra is strong, but not very dense, and is more evident on a dorsal sub-glabrous area (which may have been produced by rubbing). Each elytron carries at the base a short longitudinal crest, surmounted by yellowish-brown hairs, and a similar, but much feebler crest, in the depression between this and the shoulder. This species very closely resembles Ae/ara furcata, Bates, and is chiefly to be distinguished by the difference in form of the apices of the elytra. In furcata the apices are much more pro- duced on the outside so that the truncation has a strongly oblique direction; in vicina the elytra are only slightly prolonged at the outer apex, and the truncation of each is consequently much less oblique.

Long. 23-28 mm. Carin (district of Cheba). Two examples. Thickly clothed with an ochreous pubescence; the elytra with four plagae of a paler colour (varying from pale-ochreous to ashy-white) of which one, common, and somewhat triangular is placed at the base, one also common, and having a some- what irrezular hastate form, is placed at some distance behind the first; the remaining two are placed one on the side of each elytron, extending from beneath the shoulder almost up to the beginning of the posterior third, and slightly expanding inwards just behind the shoulder. Prothorax with the anterior margin directly transverse, the posterior slightly lobed in the middle and sinuate towards each side; disk sparsely punctate across the middle; sides sparsely punctured with each of the piligerous punctures placed at the summit of a small granule. Elytra rather sparsely punctured, and with a few larger scattered pun- ctures each occupying the centre of a minute fuscous spot. The apices of the elytra are cut away’ very obliquely from the su- ture, and being attenuated also on the outside, each ends in an obtuse point which appears to diverge from its fellow. 150.

Long. 25-29 mm. Carin (district of Cheba), alt. 900-1100 m. This species is somewhat larger than the preceding, and re- sembles it in general facies and coloration. The elytra have a brownish pubescence, with four fulvous-brown plagae — one basal, triangular ; one triangular, on each side, and placed wholly in front of the middle; the fourth common, for the most part 64 Cc. J. GAHAN behind the middle, and somewhat roughly rhomboidal in form. The anterior border of this plaga and the posterior borders of the lateral plagae are somewhat mixed with grey. At the base of each elytron, just about the middle of the lateral border of the basal triangular plaga, there is a fascicle of black and fulvous hairs. 151. Niphona ornata, sp. n.

Long. 12'/,-16 mm. Carin Mts. (Cheba district), alt. 900-1100 m. Clothed with a dense pubescence which differs in shade on different parts of the body according to the predominance of the white or of the fulvous-brown hairs of which it is mostly composed. The head and basal joints of the antennae are of a pale fulvous-brown colour, the prothorax, patches on the sides of the elytra, the underside of the body and of the legs are of a more or less whitish colour. Between the basal crest and the shoulder of each elytron there is a dark fulvous brown patch which is interrupted in the middle by a whitish line. A large angular dark-brown plaga occupies a little more than the me- dian third of the disk. Its anterior borders — directed obliquely backwards on each side from the suture — and its outer bor- ders are sharply defined; while posteriorly it passes indefinitely into the pale fulvous-brown of the hinder part of the elytra. Prothorax with a rather strongly marked tooth placed anteriorly and low down on each side; the disk with a short median ca- rina which is very narrow anteriorly, but which slightly widens and bears a feeble groove posteriorly; the anterior border of the pronotum bears a series of very small fuscous spots. The elytra, broad at the base, are much narrowed from thence to the apex, where they are each somewhat obliquely truncate and fringed with rather long hairs. LONGICORN COLEOPTERA FROM BURMA 65 In general shape and in coloration this species most nearly resembles N. plagiata, White; but the prothorax of the latter is quite rough, and does not bear a tooth on each side. Its eyes also are a little larger. 152. Niphona parallela, White, var. — N. parallela, White, Ann. and Mag. Nat. Hist., Ser. 3, Vol. II, p. 267.

The single male example which served as the type of Niphona parallela, has a broad fuscous band which extends along the middle of each elytron from the base to-beyond the middle. This band is wanting in the present variety, in which the ely- tra have everywhere a greyish pubescence mixed with fulvous brown. This is the only difference which I can detect. The eyes in this species are rather large; and the second abdominal ven- tral segment of the male has on each side a transverse semi-oval depression lined with greyish or fulvous hairs, similar to, but rather larger than, the hairy depression to be found in the same position in the males of Niphona picticornis, Muls. 153.

Long. 10-11 mm. Pronotum with alternating longitudinal bands of darker and lighter coloured pubescence, with two darker bands on each side of the middle and separated by a faint greyish line, these are succeeded on the outside by two pale fulvous or ashy lines — one on each side, and external to these is a darker vitta on each side. The elytra are strongly enough narrowed from the base, appearing as if compressed from side to side; posteriorly C. J. GAHAN. 5 66 C. J. GAHAN they are strongly declivous; the apices are obliquely truncate and very faintly emarginated towards the suture; on each ely- tron there is a distinct Jateral median fuscous plaga, which, towards the upper side, has a convex margin and is surrounded by a rather broad arcuate band of an ashy-white or fulvous-white colour. The posterior declivous portion of the elytra is also in the middle more or less ashy or pale-fulvous in colour. The punctuation of the elytra is rather strong, and is arranged some- what in rows, which on the middle of the disk are separated by slightly raised lines. This species may be recognized by the absence of a basal tuft or tubercle from the elytra, taken with its rather distinct style of marking. As it seems impossible to fix upon any definite characters which separate Praonetha from Pterolophia, 1 have been obliged to treat the first of these names as a synonym. 155.

Clothed with a brownish or fulvous-brown pubescence, with a few paler patches, and with many small points and a few spots of a dark velvety brown colour. Head moderately concave between the antennal tubercles. Prothorax transverse, sides nearly straight and very sligthly diverging from the base to within a short distance of the anterior margin where they be- come constricted; the disk transversely sinuately impressed near the apex, with a fine and straight transverse groove just before the base, and with a broad and rather faint depression along the middle; on either side of this depression there is a small LONGICORN COLEOPTERA FROM BURMA 67 tubercle. The elytra have each a small tubercle at the base, and, immediately behind the tubercle, a short longitudinal crest, while further back is another longitudinal crest which ends just at the beginning of the posterior declivity. The tubercle and crests carry tufts of hairs; the anterior crest having a continuous tuft, while on the posterior there are small tufts set at intervals. External to the crests there are on each elytron one or two raised lines. The punctuation of the elytra is rather strong and dense towards the sides, but appears finer and less dense on the disk towards the apex. Last ventral segment of the abdomen dark brown, hind margin of the first segment with a fringe of pale fulvous hairs; intermediate segments spotted with pale fulvous and dark brown. 156.

Long. 81/,-13 mm. Carin Mts. (Cheba district), alt. 900-1100 m. Head and prothorax with a not very dense fulvous pubescence. The prothorax closely punctulate, and with two somewhat ob- solete fuscous vittae along the middle of the disk. Elytra elonga- ted for this genus, almost uniformly convex above, somewhat gradually declivous posteriorly; traces of costae on the disk are scarcely apparent; the pubescence is rather close and varies from almost a grey to a reddish-brown colour, it is scantier over the irregular and not very distinct band which thus ap- pears darker than the rest of the surface; on this band also, especially at the sides, the close and strong punctuation of the elytra is more distinctly seen, while over the rest of the surface owing to the closer pubescence, it appears feebler and less dense. The apices of the elytra are very slightly truncate near the suture or are entirely rounded. 157. Pterolophia proxima, sp. n.

The coloration of this species very much resembles that of the preceding; but the antennae are almost entirely fulvous-grey: these also have a tooth at the outer apex of each of the joints from the third to the ninth. The elytra are somewhat shorter than in the last species, are transversely depressed a little be- hind the base, and are strongly and somewhat abruptly decli- vous behind. 158. Pterolophia consularis, Pasc. — Praonetha consularis, Pasc. Proc. Zool. Soc., 1866, p. 240. Carin Mts. (districts of Cheba and Ghecu), alt. 900-1400 m. The examples taken agree with the type in all respects, ex- cept that the sides of the prothorax are not so dark-brown in colour. A single example obtained at Metanja in Burma, differs from the Carin specimens in having the prothorax uniformly greyish brown above, and without the paler patch along the middle of the disk. This specimen may be considered as belonging to a variety. 159. Pterolophia armata, sp. n. Pube brevi fulvo-grisea sat dense obtecta; prothoracis dorso utrinque vilta lata brunnescente.

Body underneath, last ventral segment which is black ex- cepted, legs, sides of prothorax and front of head clothed with a pale fulvous-grey pubescence; body above and elytra brownish, with a paler fulvous-grey band extending along the middle from the head to a little beyond the anterior third of the elytra; LONGICORN COLEOPTERA FROM BURMA 69 and with an oblique greyish patch on the side of each elytron just below and behind the shoulder, each elytron also with some small black spots of which one is placed at the extreme base, a second on a tubercle a little behind the base, and three or four forming a transverse band at the beginning of the poste- rior declivity. Three or four longitudinal costae may be distin- guished on the disk of each elytron. The antennae are fulvous- brown, with the fifth and sixth joints blackish; these two joints are together scarcely as long as the fourth, the latter is slightly curved and is appreciably longer than the third joint. The an- terior coxae are each armed a small sharp tubercle which is directed towards the middle line. 160. Pterolophia annulata, Chevr. -- Coptops annulata, Chevr. Revue Zoologique, 1845, p. 99. Upper Burma (Shwegoo, Metanja) and Carin Mts. (Cheba district). The greyish-white patches on the elytra are more limited in extent than in the type, and in this respect resemble examples from North India. The specimens from China and Hong-Kong in the British Museum collection show variation in the amount of grey coloration of the elytra; so that the difference just mentioned cannot be considered of any great importance. 161. Pterolophia nigrocincta, sp. n. Modice elongata, sub-cylin- drica, capite prothoraceque griseo-pubescentibus maculis minutis nigris adspersis; elytris flavescente-pubescentibus, fascia lata trans- versa ad medium, maculis irregularibus versus basin, et punctis postice nigris; antennis articulis 1° ad 4°%™ griseo subtiliter pube- scentibus, ceteris nigris; corpore subtus pedibusque griseis. Long. 8-9 mm. Lat. 21/5-3 mm. Carin Mts. (Cheba district). This is a rather narrow and somewhat elongated species. The prothorax has its sides nearly parallel. The elytra are almost regularly convex above, gradually declivous behind, with their sides almost parallel in their anterior two-thirds, they are rather closely punctured; have a yellowish pubescence, with a well marked broad dull black band crossing them at the middle, and 70 C. J. GAHAN with two black patches at the base — one on each side — which unite together or with a smaller third spot, at a short distance behind the scutellum. Between these basal patches and the median band as well as towards the apex there are nume- rous minute black points. 162. Pterolophia socia, sp. n.

This species much resembles the last; but the greyish or yellowish-grey pubescence of the prothorax is not interrupted by minute black spots; the transverse black fascia at the middle of the elytra is much narrower; the yellowish-grey pubescence between the basal spots and the median band and between the ~ latter and the apex is not sprinkled with small black points. The antennae are entirely covered with a greyish pubescence. 163. Pterolophia alboplagiata, sp. n. (Pl. I, fig. 12).

Elytra with their sides sub-parallel for the anterior two-thirds, thence narrowed to the apex; very distinctly, strongly, and rather closely punctured; each with a well marked centro- basal tubercle surmounted by a fascicle of black hairs; with a transverse whitish fascia which reaches from the outer margin to near the suture and is much narrowed at its inner extremity; with some small and irregular spots of whitish pubescence near the base and apex. The legs have an ashy-grey pubescence. The antennae are a little shorter than the body, with the last three joints, and the apices of joints 3, 4, 5 and 8 fuscous, the remainder fulvous or cinereous.

One example. Also occurs in the neighborhood of Hong-Kong (Bowring). This species strongly resembles P. alboplagiata, but the pro- thorax appears more thickly punctured (though this may be due to its somewhat scantier pubescence), and is not ashy-white at the sides. The white band, or rather plaga, near the middle of each elytron does not reach to the suture. The legs are dark brown with a thin, and in some parts, scattered pubescence of a greyish colour. 165.

About three costae are with difficulty to be distinguished on the intermediate third of each elytron, the innermost costa only, which is the shortest being at al! distinct. On the disk of each elytron there is a small greyish area from which two ashy-white bands or patches pass off — one running obliquely outwards to reach the margin just below the shoulder, the other at first passing slightly backwards runs then in a nearly transverse direction to the outer margin. This species has some resemblance, in its mixed pubescence and general outline, to P. annulata, Chevr. and P. scopulifera, Pasc.; but may be easily distinguished by the very distinct tufted tubercle or crest at the base of each elytron. 167.

The disk and the posterior declivous portion of the elytra are more greyish or fulvous. The prothorax is entirely impunctate, unless some dark brown minute rounded spots mark out the position of some feeble punctures. The elytra are thickly and strongly punctured; each has a basal cariniform tubercle, a short prominent carina extending along the disk in the intermediate third of the length of the elytra, and ending just where the posterior declivity begins, and a slightly raised line external to this carina, ex- tending a little beyond it behind, while in front its. course may be traced up to the base. Between the basal tubercle and the anterior extremity of the carina which lies nearly in the same line with it, there is a shallow and somewhat oblique depression on each elytron. LONGICORN COLEOPTERA FROM BURMA 73 This species appears to be somewhat nearly allied to Ptero- lophia camura, Newm.; but has a generally paler and more uniform coloration, a more distinct dorsal carina on each ely- tron, and a more parallel-sided prothorax.

Long. 14 mm. Carin Mts. (district of Cheba), alt. 900-1100 m. One female example. By adhering strictly to the system followed by Lacordaire, a new genus, in the group of the Mesosides, should be formed for the reception of this species. Though it difters from all the other species of Pterolophia, and indeed from all the Niphonides, in haying a smooth cicatrix , limited by a sharp edge, on the apex of the antennal scape, yet the general ensemble of its characters is such as to bring it into very close affinity with certain forms of Pterolophia. It might be right perhaps to re- gard it as a representative of a new genus which brings into greater prominence the undoubted affinities that exist between the Mesosides and the Niphonides. It seems to me to be one of the faults of Lacordaire’s arrangement that these two groups are placed so far apart. And I also think that Lacordaire’s sub- division of the latter group may be improved upon by taking into consideration the structure of the mesonotum. In the genera more nearly allied to the Mesosides the mesonotum is pointed in front and is furnished with a stridulating surface; while in 74 Cc. J.

Long. 11- 17 mm. Carin Mts. (Cheba district), 900-1100 m.; and Thagata in Tenasserim. The pubescence which is of a yellowish or yellowish-grey tint above and grey on the underside, is somewhat uniformly spread over the whole body, but is slightly denser along certain lines of which one passes along the middle of the pronotum and four slightly raised along each elytron; of these four lines the two inner extend almost from the base and unite together at a short distance from the apex, and are thence continued back as a single line to meet another short line which arises from the junction of the two outer lines; the outermost line may be traced forwards almost up to the shoulder, the one next it disappears anteriorly after passing the middle of the elytron. The punctures of the elytra are, behind the middle, arranged more or less regularly in double rows between the 76 Cc. J. GAHAN raised lines; anteriorly their numbers increase and the regula- rity of their arrangement is disturbed. The structural characters by which this species differs from M. aridus, Pasc. — the type of the genus — are not sufficient to justify the creation of a new genus for its reception. With the exception of its more parallel-sided prothorax, its slightly longer antennae, and more prominent antennal tubercles, it agrees essentially in generic detail with M. aridus. 180.

This species may be easily distinguished from the preceding by the more abrupt manner in which the elytra are turned down at the apex. This apical declivous portion is closely co- vered with a dirty-white pubescence, and is also furnished with some small tufts of a similar colour — about four to each ely- tron, of which one is at the summit of the declivity and marks the posterior extremity of a very short and feebly raised carina which is in a line with some granules placed at wide intervals along the disk of the elytron; the second tuft is at about the middle of the declivity, and the remaining two are at the po- sterior border and give to the latter a deeply emarginate ap- LONGICORN COLEOPTERA FROM BURMA TTI pearance. The prothorax is rather feebly and not very closely punctured, it is slightly rugose towards each side of the disk, and on the middle of the disk bears four minute granule-like tubercles. The elytra are strongly and closely punctured, the punctures being only partially hidden by the not very dense pale-grey pubescence. The antennae are about equal in length to the body. The single specimen taken is probably a female. 184. Sybra (?) posticata, sp. n. Flavo vel fulvo-albido-pubescens, capitts fronte, prothoracis disco elytrisque plus minusve brunne- scentibus; capite inter tuberculos antenniferos sat anguste forti- lerque concavo, occipite maculis duabus fusco-velutinis; prothorace supra ante medium longitudinaliter rugoso, postice rugoso-punctlato, scutello albido; elytris postice sat valde declivis, parte declive pal- lidiore, apicibus truncatis; femoribus intermediis posticisque versus apicem et abdominis lateribus fusco irregulariter denseque macu- latis; segmento ultimo medio fusco-plagiato; antennis ( ¥) corport aequalibus, (Q) brevioribus: griseis, articulis intermediis infuscatis. Long. 11-138 mm. Catcin Cauri and Bhamo in Upper Burma. Thagata in Tenas- serim; also Darjeeling and Cambodia (Brit. Mus. coll.). The antennal tubercles are somewhat more prominent on the inner side and separated by a narrower interval (somewhat y-shaped when looked at from above) than is usual in the genus Sybra. The elytra also are more strongly declivous posteriorly. Each of the intermediate cotyloid cavities, though in fresh spe- cimens appearing to be completely shut off from the epimeron on the outside, in reality extends out to it; the narrow outward extension being occupied by the trochantin when the femur is turned backwards. Lacordaire has laid stress upon the closing in of the intermediate cotyloid cavities in the group to which Sybra belongs. « Pris dans son ensemble, il est trés-voisin des Apomécynides et n’en différe essentiellement que par la ferme- ture des cavités cotyloides intermediaires ». This is not however, a reliable character. A careful examination of the different species of the Ptericoptides will show that in very few, if any, are the intermediate cotyloid cavities completely shut off from the meso- 78 Cc. J. GAHAN thoracic epimeron. They often, as in the species just described, appear to be so, owing to the concealment of the narrow outer prolongation of the coxal cavity by the rather thick pubescence which overlaps it, the trochantin itself also being often slightly pubescent on its outer edge. In many of the species of the Pte- ricoptides that I have examined the mesothoracic epimeron is more distinctly in connection with the cotyloid cavity than is the case in such genera as Apomecyna and Mycerinopsis. 185.

Also occurs in Assam and Siam. The descriptions given by Thomson and Lacordaire (and pro-_ bably drawn up from rubbed specimens) do not quite accurately fit the examples. now before me, so that I have some doubt in referring the latter to Thomson’s species. The pubescence is grey, with seven fulvous-red lines along the thorax and the same number on the elytra. The latter in fresh specimens have numerous small dull black spots, and two larger sub-nitid black spots — one on each shoulder. Of the seven reddish lines on the elytra, one is a common sutural line, one at the extreme outer margin of each elytron; the three intermediate lines on each side are here and there interrupted in their course. The front of the head is rather thickly and somewhat asperately punctured, the prothorax is obsoletely punctured above, and is rather feebly wrinkled across the middle. The elytra are thickly but not very strongly punctured. The vertex of the head in this, as in almost every species of the group, has two short black glabrous and slightly elevated lines, placed one on each side of the middle line and extending for- wards from the occiput. LONGICORN COLEOPTERA FROM BURMA 79 187. Hyllisia lineata, sp. n. Fusca; capitis fronte verticeque dense punctatis; prothorace sat dense punctato, vittis quinque pallide fulvis; elytris dense punctulatis, fusco-castaneis, sutura et utrinque lineis quatuor vel quinque pallide fulvis, apicibus sub-truncatis; corpore subtus pedibusque subtiliter griseo pubescentibus, pectore vitla fulva utrinque; antennis (7) quam corpore plus duplo lon- gioribus, subltus usque ad medium longe sat denseque ciliates, arti- culo 1° basin prothoracis fere atlingente. Long. 15 mm. Teinzo in Upper Burma; also India (Brit. Mus. coll.). The antennae in the male of this species are more than twice as long as the body, the first joint, cylindrical in form or very slightly flattened underneath, reaches almost to the base of the prothorax , it is ciliate underneath; the third joint, which is distinctly longer than the first is, together with the following joints up to about the middle of the sixth, provided with a thin fringe of very long hairs underneath. The head is thickly pun- etured in front, as well as on the vertex. The prothorax is strongly enough but not very thickly punctured. It has three narrow pale-fulvous vittae above and one — broader — on each side. The elytra are thickly but rather feebly punctured; the suture and four or five lines on each elytron are covered with a pale-fulvous pubescence, the intervals almost, glabrous and subnitid, are of a dark chestnut-brown colour. The legs and underside of the body have a slight greyish pubescence , with a pale fulvous vitta on each side of the meso and meta- thorax. The hind femora reach to about the middle of the se- cond. abdominal segment. 188. Hyllisia consimilis, sp. n. H. lineatae persimilis sed minor; scapo antennarum apice anguste cicatricoso; apicibus elytrorum oblique truncatis. Long. 10-11 mm. Carin Mts. (Cheba district), alt. 900-1100 m. This very closely resembles the preceding species, but is di- stinctly smaller; the head is less strongly and less thickly pun- ctured above and exhibits no trace of the two feebly elevated . glabrous lines; the delicate hair fringe of the antennae is not so long (this character may not be of specific importance, as in 80 Cc. J. GAHAN one or two undescribed species the individuals seem to vary with regard to the length of the hairs or ciliae on the anten- nae); the scape of the antennae has, at the inner apex, a nar- row cicatrice bounded by a very fine edge. There is some trace of a cicatrice in the same position in H. lineata, but in this species I have not been able to detect a limiting carina. In the present species also the apices of the elytra are somewhat more distinctly truncate. Closely as this species resembles 4. lineata, its resemblance to a South African form (? H. subvirgata, Fairm.) is scarcely less pronounced. The latter species has the same general facies and style of coloration. The scape of its antennae is also furnished with a very narrow smooth cicatrice, limited by a sharp but very feeble carina. The apices of the elytra are more obliquely truncate, becoming in fact sub-acuminate. The most essential difference between the two species lies in the prosternum, which in the African species is not only nar- rower between the coxae, but does not widen out to nearly so great an extent posteriorly. Hippopsis tonkinea, Fairm., appears to be very much like Hyllisia consimilis and probably belongs to the same genus. 189. Smermus sericeus, sp. n. Fuscus, pube griseo-sericea, ely- tris plagiatim condensata, vestitus; prothorace vittis tribus fulvo- griseo-sericeis; capite fronte sat dense, vertice densissime punctato, prothorace elytrisque sat dense punctatis; his punctis paullo pone medium evanescentibus, apicibus utrisque fere regulariter rotundatis, corpore subtus pedibusque pube fulvo-grisea sericea sat uniformiter denseque vestitis. Long. 15-17 mm. Carin Mts. (Cheba district), alt. 300-1000 m.; also Burma (Brit. Mus. coll.). Though at first sight looking rather unlike Smermus Mnis- sechi, Lac. — the type of the genus — there can be little doubt that the true place of the present species is in this genus, with which it agrees in all its chief structural chara- cters. The prothorax is somewhat shorter and is more thickly punctured than in Mniszechi. The elytra are each almost regu- larly rounded at the apex. The length of the antennae in the LONGICORN COLEOPTERA FROM BURMA sl examples before me is from three to four times that of the body. A closely allied species occurs in Java. This species (Smermus similis, sp. n.) differs from sericeus in having slightly obliquely truncated apices to the elytra. The size is smaller. Long. 12 mm. The pale fulvous-grey silky pubescence of the elytra forms somewhat irregular longitudinal bands uniting at the apex, and with a darker, somewhat brownish , pubescence filling in the intervals anteriorly. The vertex of the head is much less thickly punctured. 190. Tetraglenes bucculenta, sp. n. Linearis, fusco-testacea, pube fulvo-brunnea sat dense oblecta; capitis vertice prothoracisque dorso linea media, et ulrinque vitta minus dense pubescentibus; capite bast lato, genis prominentibus; elytris crebre sat fortiter punctatis, lateribus fere parallelis, versus apicem angustatis, apicibus oblique truncatis, sub-divaricatis; antennis (2) corpore aequalibus, fuscis; subtus longe, supra minus longe, sat denseque ciliatis. Long. 12 mm. Teinzo in Upper Burma. One female example. This species ought, perhaps, to constitute a genus distinct from Tetraglenes. Its head is somewhat difterently shaped, being very much wider at the base, with prominent cheeks, and (considering the size of the insect) very strong mandibles; the antennae in the female are quite as long as, or rather longer than, the body; the relative proportions of the joints are how- ever nearly the same as in 7’. insignis, Newm., with the exception of the first joint which is relatively shorter. The elytra have their sides nearly parallel in their anterior fourth fifths , and are narrowed towards the apex, where each is cut back obli- quely from the suture, so that they appear slightly divaricate. The species, though more uniform in coloration, bears a strong general resemblance to Tetraglenes insignis, and may provision- ally be considered congeneric with it. 191.

Hist., XVIII (1846), p. 49, pl. I, fig. 4. Carin Mts. (district of Cheba), alt. 900-1100 m.; Teinzd in Upper Burma. The head in this species is shaped like that of Tetraglenes insignis; and the eyes also offer the same characters. White unfortunately and, we may add, carelessly described and figured a specimen in which the head was misplaced. The front of the head was uppermost, the vertex in front, while that part of the head which ought to have been inserted in the prothorax did duty for a mouth. No wonder, therefore, that, as White remarks, the mouth-parts were wanting. This explanation will account for Lacordaire’s observations on the genus. Estigmenida, gen. nov. Intermediate cotyloid cavities open. Claws of tarsi divergent. A sinus on the intermediate tibiae. Head with the front trape- ziform and oblique, the antennal tubercles somewhat prominent and slightly divergent; the mouth parts applied to the anterior coxae when the head is fully retracted. Prothorax slightly con- vex above, scarcely longer than broad, with the sides sub-pa- rallel and unarmed; with the pronotum in the middle line about twice as long as the prosternum; the latter forming a very narrow boundary to the coxal cavities in front, rather narrow in the middle between the coxae, but widening out considerably behind. Elytra nearly one half broader than the prothorax, their sides very gradually narrowed and almost parallel in their an- terior three fourths and thence mere strongly narrowed to the apex; the latter truncate. Each elytra with three or four costae of which one lateral and outermost is somewhat more promi- nent than the rest. The mesosternum is, like the prosternum, almost flat; it gradually narrows posteriorly. The legs are of moderate length; the femora slightly incrassate below the middle; the middle coxae of the male each with a small sharp conical tubercle at its inner summit. LONGICORN COLEOPTERA FROM BURMA 83 Antennae of the male about equal in length to the body; first joint rather short and thick, the third nearly twice as long, the fourth distinctly shorter than the third, the fifth and follow- ing subequal among themselves, each very much shorter than the fourth; the third, fourth and fifth with a short thick fringe of hairs underneath. The antennae of the female resemble those of the male; but are much shorter; surpassing by a little only the middle of the elytra. The combination of characters above described shows that this genus does not fit well into any of Lacordaire’s groups. It is undoubtedly nearly allied to Pemptolasius, to which I have already, with some doubt, assigned a position near Ectatosia. 193. Estigmenida variabilis, sp. n. (Pl. I, fig. 13).

The resemblance of this species to Estigmena chinensis, Hope — a tolerably common Oriental Hispid — is most striking, and appears to me to be the result of something more than mere accidental causes. Not only are the colours, punctuation, and whole general aspect of two species very much alike; but the antennae of the Longicorn do not show so great a difference from those of the Hispid, as, from their greater length, they might be expected to. This is due to the fact that the last six joints are slender, are mostly of a pale-greyish colour, and are not fringed with hairs like the basal joints, and in consequence are not so distinctly visible at a short distance. What advantage the Longicorn could derive from thus mimicking the Hispid is 84 C. J. GAHAN not obvious; indeed the sober style of coloration, or absence of bright warning colours, seems opposed to the idea that the Hi- spid might be recognized by insectivorous animals as a dista- steful morsel. 194.

The elytra with black markings consisting, on each, of: 18t a short basal vitta which unites, behind the scutellum, with its fellow to form a triangular or y-shaped figure; 2°¢ an irregular patch placed below, and extending a little behind, the shoulder; 3° a trans- verse plaga or fascia situated at about the middle; and 4 a somewhat similar plaga between the middle and the apex. The prothorax is longer than broad, somewhat constricted towards the base, with the sides feebly rounded in the middle, and each furnished with a minute and almost imperceptible tooth; the disk exhibits some minute, asperate, scattered punctures. The elytra appear rather thickly punctured towards the base and as far as the middle, but are almost impunctate towards the apex. The disk of each elytron in the male is armed at some distance from the base with a small backwardly directed spine. In three examples from the Carin Hills, which I take to be females of this species, on account of their very close agreement in colour and markings with the male type, this discal spine of the elytra is wanting; the disk of the prothorax also does not show the asperate punctures which are present in the male. The species is undoubtedly congeneric with R. spinosula, Pase. LONGICORN COLEOPTERA FROM BURMA 85 but may be readily distinguished by certain structural characters as well as by its colour and markings. Its elytra are obliquely truncate and not emarginate nor mucronate at their apices; nor are they asperate at the base. In view of the nature of the sexual differences in the present species, I think it not unli- kely that R. simplex, Pasc. may prove to be the female of R. spinosula, Pasc. 196.

Prothorax with a lemon-yellow band on each side; the upper borders of these bands are sub-parallel, so that the median dorsal space enclosed between them is nearly oblong in shape. Elytra with a basal transverse band, two large rounded spots at the middle which touch one another at the suture, two smaller spots before the apex, and two very small spots placed at the extreme apex, lemon-yellow. Sides of the breast similarly coloured. Apices of the elytra with the inner angles slightly, the outer angles strongly and distinctly, spined. Legs yellowish brown. This species somewhat resembles Glenea vesta, Pasc. but may may be distinguished by its paler colour; the oblong form of the dorsal median brown space of the prothorax; the presence of two distinct spots, conjoined at the suture, which are placed at the middle of the elytra, and of a small transverse or slightly oblique spot at the extreme apex of each elytron. The abdomen moreover is almost entirely reddish brown underneath. 211. Glenea cancellata, Thoms. — Syst. Ceramb. Appendix, p- 565.

Long. 14. Lat. 4 mm. Upper Burma, Bhamo and Catcin Cauri. Testaceous, clothed with a fulyous-brown pubescence. Pro- thorax with two fulvous-grey vittae on each side of the me- dian dorsal carina; these vittae are bounded by black lines four in number, and extend on to the occiput of the head; the sides of the prothorax have each two indistinct greyish ful- vous bands. Elytra fulvous-brown, with black markings which include a narrow glabrous spot on each shoulder, two conjoined spots on each elytron just before the middle, three short vittae between the middle and apex (the two outer of which are longer than the innermost and unite posteriorly) and a trans- verse spot or band at the apex. Each elytron has two carinae at the side, and one on the disk; the latter carina is distinct enough near the base but becomes obsolete before the middle. Elytra rather sparsely but distinctly punctured; prothorax with a few indistint punctures. Legs and body underneath testaceous, with a fulvous brown pubescence; the tarsi and the inner side of the hind femora somewhat blackish; claws of the male ap- pendiculate; first joint of the four anterior tarsi in the same sex rather strongly dilated. Antennae black, with a slight greyish pubescence underneath. 213. Glenea nigromaculata, Thoms. —- Systema Cerambycida- rum. Appendix, p. 566. Glenea? Amelia Gahan, Trans. Ent. Soc.

The females possess also that peculiar character of the claws of the tarsi which I have already pointed out (loc. supra cit.) as existing in the males.

There is a considerable amount of variation, in the coloration of the prothorax amongst the examples which I refer to this species. In some the prothorax is entirely fulvyous, in some there is a small greyish-black spot on each side of the disk; in others these spots elongate to become vittae, while in a fourth set of examples the upper side of the prothorax is almost entirely greyish-black. The elytra in all are greyish-black, with a dorsal fulvous vitta, narrowing from the base, on each elytron. This vitta in some examples is exceedingly short, forming in fact a mere basal spot; while in others it extends almost to the apex of the elytra. The punctuation of the elytra in one series of examples appears to be somewhat stronger than in another set; but as this character also is variable, and the difference slight, I am forced to regard all the examples as belonging to a single variable species. Examples were taken by M. Fea at Bhamo in Upper Burma, at Palon in Pegu and at the district of Cheba, Carin Mts. — The British Museum collection contains examples from Assam Siam, Burma, and Perak. 217.

LONGICORN COLEOPTERA FROM BURMA 91 Carin Mts. (Cheba district). Fulvous or yellowish-testaceous. Head, antennae, the apical fifth or sixth of the elytra, the apical half of the last abdominal segment, the posterior tibiae and tarsi black. Prothorax with its sides subparallel, or very slightly rounded in the middle between the anterior and posterior transverse grooves; the width of the prothorax slightly exceeds its length, the difference being more marked in the female than in the male. Elytra rather strongly and thickly punctured as far as the apical black patch, with the punctures arranged more or less regularly in close longitudinal rows. The disk of the elytra is slightly flattened and depressed a little below the base, and has an obsoletely raised line towards its outer edge on each side; the sides of the elytra have each a rather indistinct longitudinal carina; the apices are truncate in a slightly oblique direction, the inner angles being less prolonged than the outer. The antennae in both sexes are longer than the body, those of the male exceed- ing it by about the last three joints. The last ventral abdo- minal segment of the male has a rather deep semi-oval depression along its hinder half. From N. ustulata, Erichs. which it very closely resembles, the present species may be distinguished by its black-head, slightly longer antennae, and the less distinct lateral carinae of its elytra. ; 219.

Long. 10-12 mm. Carin Mts. (Cheba district), alt. 900-1100 m. Prothorax rather broader than long, feebly swollen on each side just in front of the basal transverse groove; the disk with a faint median raised line.

Taken by Signor Fea at Bhamd in Upper Burma, at Carin Mts. 400-600 m.; at Palon, at Rangoon and at Thagata. This species is subject to a certain amount of variation in the extent to which the black coloration spreads over the basal half of the elytra. In a male example taken at Bhamoé the black on the basal half of the elytra is confined to a small longitudinal patch on, and behind, each shoulder. In a female specimen from Thagata the anterior sixth of the elytra is testaceous, the grey-black colour forming a zone between this and the middle. In those examples in which the grey-black is most extensive , there is still a small testaceous patch left at the extreme basal margin. In other respects the species appears to be constant enough. The transverse black fascia at the apex of the elytra is always very distinct. The lateral carina passing back from each shoulder is sharp and prominent, but does not extend quite up to the apex; the dorsal costa on each side limits ex- ternally a rather broad shallow depression which lies between it and the suture. The black antennae are about equal in length to the body in the female, a little longer in the male. Tarsal LONGICORN COLEOPTERA FROM BURMA 93 claws of both sexes appendiculate.

Long. 12-15. Lat. 3- 41/, mm. Carin Mts. (Cheba district), and Upper Burma (Bhamo). Fulyous, with a faint greyish pubescence. Elytra with the apical fourth or fifth black, the rest yellowish testaceous: clo- sely and rather strongly punctured up to a little beyond the middle; with a well defined carina on each side which does not quite reach to the apex; the disk not depressed and scarcely even flattened along the middle, without a distinct costa; apices truncate in a slightly oblique direction, with the angles very feebly mucronate. Body underneath fulvous, with a small spot on the side of the prothorax, the sides of the meso-and meta- thorax, and tip of abdomen blackish. Legs fulvous, with all the tarsi, the hind tibiae, and, to a slight extent, the middle and hind femora blackish-brown. In its general build and in the form of its prothorax this species has a close resemblance to N. variabilis, and to an un- described species from North India; its antennae are, however, quite different, being slenderer and longer, and having the fourth joint equal in length to the second and third united. 222.

The lateral carina of the elytra is less distinct in this species than in most of the known species of Nupserha. In size and coloration it somewhat resembles NV. ustwlata, Erichs., from which it is easily to be distinguished by the character just mentioned as well as by the absence of a distinct dorsal costa from the elytra, the obscurely annulated antennae and other less im- portant characters. The last ventral segment of the male of the present species has a rather deep triangular depression on the posterior third. Nupserha annulata, Thoms. (Stébara) approaches the present species very closely in structural characters, and is to be di- stinguished from it by its concolorous (yellowish-testaceous) apices of the elytra, the more distinct fuscous colour at the margins of the elytra, which, however, does not reach the base or apex, the fuscous spot or band at each side of the prothorax, and by the almost entire greyish-black colour of the underside of the body. 223.

Long. 13-18 mm. e LONGICORN COLEOPTERA FROM BURMA 95 Teinzo in Upper Burma, Meetan and Carin Mts. (district of Cheba). The British Museum has examples from Darjeeling, Nepal, and Sylhet in North India. This species is to be distinguished from those having a similar coloration, by the deep and rather broad excavation which oc- cupies nearly the whole length of the ventral side of the last abdominal segment in the male. The abdomen, like the apices of the elytra, is usually tipped with brownish black. The hind femora do not reach beyond the middle of the second abdominal segment. From 0. fuscipennis, Chev., which it most nearly resembles, the species may be distinguished by its somewhat nar- rower and more elongated prothorax, and the much deeper excavation of the last abdominal segment of the male. 226. Oberea armata, sp. n. Fulvescens; elytris brunneo-testaceis, griseo leviter pubescentibus, versus basin pallidioribus; antennis nigris, tibiis posticis infuscatis; prothorace quam longiort manifeste latiori, dorso medio sub-gibboso; elytris dense jpunctatis, medio angustatis; segmento primo abdominis pallido, ad apicem medio processu angusto armato (7), segmento ultimo prope apicem subtus leviter cordato-impresso, apice truncato; femoribus sposticis quam segmentis duobus basalibus abdominis paullo longioribus. Long. 16 mm. Thagata, Tenasserim and Carin Mts. (district of Cheba). Fulvous; elytra somewhat pale brown with a greyish pube- scence. Prothorax broader than long, slightly gibbous on the middle of the disk. First segment of the abdomen in the male produced behind into a narrow median process which extends back almost three fourths the length of the following segment. This process is slightly expanded towards its extremity, where also it bears a short and not very dense fringe of fulvous hairs. The last ventral segment of the male is truncate at the apex, just in front of which it bears a feeble heart-shaped depression. The antennae are black, and somewhat shorter than the body; the third joint is scarcely perceptibly longer than the fourth. The hind femora reach a little beyond the hind border of the second abdominal segment. 96 Cc. J. GAHAN This species has a close general resemblance, and is probably nearly allied, to O. fuscipennis, Chevr. In the latter species the elytra are less pubescent and somewhat more strongly punctu- red, the last ventral segment of the male has a larger and deeper depression, and the first segment is concolorous and unarmed. The curious abdominal process with which O. armata is provided seems to be confined to this species. I do not re- collect the occurrence of anything similar to it elsewhere among the Longicorns. A somewhat similar process does, however, oc- cur among certain species of Galerucinae (Gen. Hoplasoma, Jac.). 227. Oberea Birmanica, sp. n. Fulvescens; elytris lateraliter posticeque sub-infuscatis; pedibus posticis abdomineque fuscis, hoc. segmento primo tolo et secundo in medio argenteo-sericeis, ceteris medio subtiliter griseo-sericeis; antennis (articulis 1°, 2°que fulvis, exceplis) nigrescentibus, quam corpore brevioribus, articulo 3° quam 4° longiori; prothorace quam longivri distincte latiori, lateribus rotundatis. Long. 16-19 mm. Upper Burma, Teinzod and Bhamo. This species agrees very closely in structural details with O. curialis, Pasc., which occurs in Sumatra, Java and Penang. The difference is chiefly one of colour. In curialis the elytra are distinctly black, while the head and prothorax are reddish. In the present species the elytra are fulvous, testaceous some- what infuscate externally and towards the apex; the head and prothorax are yellowish tawny. So far as I can judge from the few specimens of each form that I have seen, these differences remain constant; though possibly the species I have just described may prove to be only a local or pale variety of O. curialis. 228. Oberea sericea, sp. n. Cupite, prothorace et corpore subtus fuscis, pube griseo-sericea dense obtectis; elytris testaceis, lateraliter posticeque et ad suturam infuscatis, pube griseo-sericea minus dense oblectis; pedibus testaceis, posticis tibiis femorumque apicibus fuscis; antennis nigrescentibus. Long. 13. Lat. 3 mm. Carin Mts. (Cheba district). Alt. 400-900 m. One example. Head, prothorax, scutellum and underside of body with a dense pearl-grey pubescence which has a lustre like that of LONGICORN COLEOPTERA FROM BURMA 97 shot silk, appearing lighter or darker in shade according to the light in which it is viewed. The elytra have a similar but less dense pubescence through which can be seen the colour of the derm, testaceous at the base and for some distance along the middle of each, dark brown posteriorly and along the sides and suture. The prothorax is scarcely broader than it is long, and has its sides almost perfectly straight and parallel. The hind tibiae, the distal half of the hind femora, and all the tarsi are more or less infuscate; the remaining portions of the legs are yellowish testaceous. The hind femora reach beyond the middle of the third abdominal segment. 229. Oberea modica, sp. n. Modice elongata, fulvescens; protho- race quam longiori vix latiori, antice posticeque sulcato, lateribus medio via rotundatis; elytris supra deplanatis, linealim punctatis, apicibus lateribusque (his versus basin exceptis) infuscatis; antennas quam corpore longioribus, nigris, vel articulis intermediis basi fusco-testaceis, articulo 4° quam 3° longiori. Long. 12-14. Lat. 3-31/, mm. Bhamé in Upper Burma; also Northern India (B. M. col- lection). Fulvous; sides of the elytra (towards the base excepted) and apices dark brown. Antennae black; tarsi and hind tibiae infu- scate. Prothorax scarcely broader than long, transversely sul- cate anteriorly and posteriorly; with its sides very feebly roun- ded in ‘the middle and almost parallel. Elytra flattened or slightly depressed along the middle above; closely punctured, with the punctures arranged in more or less regular lines; apices truncate, with the angles scarcely acute. Antennae dis- tinctly longer than the body, black, or with the intermediate joints somewhat brownish testaceous at their bases; the fourth joint almost equalling in length the second and third united. Hind femora reaching to the apex of the third abdominal seg- ment. This species belongs to a small group whose somewhat shortened form brings them into close resemblance to species of Nupserha, from which, however, they are to be distinguished by the absence of a distinct lateral carina to the elytra. O. mar- C. J. GAHAN. 7 98 C. J. GAHAN ginella, Bates, which also belongs to this group, may be distin- guished from the present species by its black head, the more clearly limited fuscous vitta at each side of the elytra, and by the structure of the last dorsal segment of the female which ends in two sharp teeth between which is a deep but rather narrow emargination. In the present species this plate is rounded at the apex. 230. Oberca pallidicornis, sp. n. Precedenti affinis sed differt elytris medio leviter angustioribus, antennis (articulis 1°, 2°que nigris exceptis) pallide teslacets, articulis 3° ad 6°™ apice angu- slissime nigris. Long. 12. Lat. 2'/, mm. Carin Mts. (district of Cheba). Signor Fea has taken two examples, which though closely allied to, appear to be distinct from the preceding species. They have on the whole a somewhat narrower form: the front of the head in the male is decidedly narrower than in modica, and in this sex also the last ventral segment is very feebly or scarcely at all impressed. (In a North Indian example which I take to be the male of 0. modica this segment has a distinct , though not strongly marked, longitudinal impression). 231. Oberea brevis, sp. n. Fulva, elytris lateraliter posticeque infuscatis, apicibus oblique truncalis fere rotundatis; capite pro- thoraceque dense punctatis, hoc lateribus fere parallelis; elytris crebre punctatis, punctis postice evanescentibus; antennis articulis 1° ad 3"™ nigro-fuscis, ceteris obscure testaceis, apicibus fuscis; articulo 3° quam 4° vix longiori. Long. 91/,. Lat. 2'/, mm. Bhamo in Upper Burma. One female example. Male, without indication of locality, in Brit. Mus. collection. Fulvous. Sides and hinder part of elytra turning to dark brown. Antennae longer than the body in both sexes with the first three joints black-brown, the remainder more or less testa- ceous; the third joint barely longer than the fourth. Hind legs not much longer than the middle or anterior pairs; their femora reaching almost to the hind border of the third abdominal seg- ment. Last ventral in the female rather long, and marked with a distinct longitudinal line; the same segment in the LONGICORN COLEOPTERA FROM BURMA 99 male somewhat shorter, emarginate at the apex, and slightly impressed in the middle just before the apex. This is one of the shortest species of Oberea known me. In its size and general aspect it resembles some of the European species of Phytoccia, and in fact cannot be separated from them by any decided structural characters. On the other band I see no good reason for separating it generically from such species as Oberea marginella, modica, sericea and others. 232. Phytoecia amoena, sp. n. (PI. I, fig. 16). Pube sulphurea, nigro ornata, obtecta; antennis griseo-nigris, pedibus testacets, griseo subtiliter pubescentibus. Long. 9 mm. Carin Mts. (Cheba district). Alt. 900-1100 m. One female example. Clothed with a sulphur-yellow pubescence, with black mar- kings. Head with a black spot on the lower part of the front, and with a triangular spot on the occiput, with a median line uniting the opposed apices of the two spots. Prothorax with its median length about equal to its anterior width, its sides nearly parallel and slightly constricted just before the base; the disk with two elongated black spots placed one on either side of the middle line, the sides each with a small black spot. Elytra each with a submarginal black line passing back from the shoulder along the outer edge of the disk as far as the middle, a line passing from a little behind the base, close to the suture, as far as the middle where it unites with a black spot, and, between this point and the apex, two transverse black spots or fasciae, the posterior of which is much narrower than the anterior, and which are united at their sutural extremities by a narrow black line. Sides of the elytra almost parallel, apices transversely truncate. Body underneath with a sulphur yellow pubescence, which is somewhat less dense along the middle. Legs testaceous, with a faint greyish pubescence. This species has very much the general aspect of a small Saperda. Its position in Phyloecia is necessitated by the cha- racter of its tarsal claws, which are distinctly appendiculate. 100 Cc. J. GAHAN 233. Astathes gibbicollis, Thoms. Systema Ceramb. p. 559.

Long. 11-13 mm. Bhamd in Upper Burma. One example. Also North India (Brit. Mus. Coll.). Yellowish testaceous or fulvous; the elytra somewhat paler; hind-breast, abdomen and the posterior fifth or sixth of the elytra dark metallic blue. Head feebly and sparingly punctured, the front projecting in the middle in the form of a carina or laterally-compressed tubercle, which is less well marked in the female. Prothorax somewhat more thickly and more strongly punctured; the disk with a tolerably distinct, though not sharply limited, central umbone or swelling which is somewhat rounded or transversely-oval in shape. Elytra rather thickly punctured over the whole of the yellow area; less thickly and not so manifestly punctured on the dark-blue apical portion. In addi- tion to these larger setigerous punctures, the interstices between them exhibit a very fine punctuation. This species somewhat resembles Chreonoma dilecta, Newm. (Phea) but the latter has the antennae almost entirely black, the whole of the underside of the body fulvous testaceous, the apex of the elytra piceous; the prothorax also is less thickly punctured, is very feeble raised on the middle of the disk , and the lateral tubercles are almost obsolete; the head of the female has a raised line along the middle of the lower part of the front. Chreonoma melanura, Pasc., seems, from the de- LONGICORN COLEOPTERA FROM BURMA 101 scription, to have a similar style of coloration to the present species; but may be distinguished by its dark hind legs, and by its different punctuation. ADDENDA. The following species had been held over in the hope that a comparison with types in Pascoe’s collection might lead to their identification. They seem, however, to be new; but only those represented by well preserved specimens are described. 237. Gen.? sp. Thagata in Tenasserim. This, apparently new genus, is represented by only a single somewhat imperfect specimen. It has the shortened elytra of Epania or Necydalis; but this character is accompanied by a roundness and fullness of the prothorax which is more suggestive of the Clytides. The femora are strongly clavate, but less abruptly so than in Epania. The state of the specimen does not permit me to examine sufficiently the structure of the cotyloid cavities. 238. Demonax quadricolor, sp. n. Capite prothorace, corpore subtus, pedibusque et antennis cinereis, episternis meso-, metathora- cisque albescentibus; elytris fasciis pubescentibus ornatis, prima basali cinerea, maculam nigram oblique elongatam includente, se- cunda angusta, nigra, valde obliqua, tertia griseo-fulva triangulari, viz pone medium posita, quarta fulvo-brunnea transversa, quinta griseo-fulva, lata, transversa, apicali; antennis (Q) medium ely- trorum haud superantibus, articulis 3°, 4°que extus breviler spinosis. Long. 10'/, mm. Hab. Mount Mooleyit in Tenasserim. Alt. 1000-1900 m. This species somewhat closely resembles D. salutarius, Pasc. and other species in the pattern of its markings, but it may be 102 C. J. GAHAN distinguished by the colour of the three posterior bands of the elytra; the middle one of these is fulvous-brown in colour, while the submedian band, immediately in front of it, and the apical band, just behind it, are both of a somewhat greyish- tawny shade. The third and fourth joints of the antennae are very briefly spined at the outer distal angle. 239. Blepephaeus parvicollis, sp. n. Pube fulvo-brunnea sericea sat dense vestitus; elytris albido-cinerascentibus, plaga triangulari, ad basin et plaga subtriangulari et sub-elongata utrinque brunnco- velutinis; capite prothoraceque fere impunctatis, hoc lateraliter ulrinque sat valde spinoso, supra tuberculis tribus parvis, et postice granulis nigris paucis obtecto; elylris versus basin sparse asperato- punctatis; apicibus rotundatis; mesosterno medio sat distincte tuber- culato, libiis intermediis prope medium leviter oblique emarginatis. Long. 23. Lat. 8 mm. Hab. Catcin Cauri in Burma. The relatively great width of the elytra as compared with the head or prothorax (the width of the elytra across the base being about twice that of the base of the prothorax) gives to this species a characteristic appearance. Some of its remaining characters do not quite agree with those of the genus Blepe- phaeus. The mesosternum has a small but distinct tubercle at about the middle of its length; the middle tibiae bear an evi- dent, though feeble, oblique groove just below the middle. 240. Batocera, sp. Palon in Pegu. One somewhat rubbed specimen. 241. Pterolophia chebana, sp. n. ¢. Fusca, pube fulvo-grisea, fusco-mixta sub-maculatim vestita; anlennis medium elytrorum paullo superantibus, articulis 3° et 5° ad 11"™ basi anguste fulvo-griseis, 4° fulvo-griseo, apice fusco; capite prothoraceque sparse punctalis; elytris dense fortiterque punctatis, punctis sub-oblongis, dorso sub- planis haud cristatis. Long. Hab. Carin (district of Cheba; alt. 900-1100 m.). One female example. Head very sparsely punctured, clothed with a not very dense greyish tawny pubescence. Prothorax a little more strongly and LONGICORN COLEOPTERA FROM BURMA 103 tore thickly punctured, with a similar greyish tawny pubescence, which is more widely interrupted by dark brown. It is only slightly convex above. Elytra with a fulvous grey pubescence , a good. deal interrupted with dark brown towards the base, and crossed by a broad but rather indistinct dark brown band just behind the middle. They are slightly flattened above, and are thickly punctured with rather large and sub-oblong punctures, which are more distinctly seen on the less pubescent dark brown areas; they are strongly enough and regularly declivous behind, with the apices rounded. The antennae of the female are about equal in length to three-fourths of the body; the fourth joint is widely, the other joints (first, faintly fulvous excepted) nar- rowly covered with fulvous-grey pubescence at the base. This species is more flattened and more even above, and the vertical height of the elytra consequently less than is the case with the great majority of the species placed in the genus Pterolophia (= Praonetha). 242. Pterolophia bimaculata, sp. n. Swb-angusta; capite fulvo- pubescente, supra fusco-bipunctato; prothorace griseo, supra bituber- culato; elytris sat dense punctatis, pube grisea, fulvescente paullo mixta, sat dense vestitis; utrisque bast breviter haud distinete cri- stalis, postice sat gradatim declivis et macula elongata paullo arcuata fusca instructis, apicibus sub-truncatis; pedibus supra fulvo-brunneis, sublus cinereis; antennis (Q) medium elytrorum paullo superan- tibus. Long. 9. Lat. 3 mm. Head with a fulvous-brown pubescence; vertex with two small sub-glabrous black spots. Prothorax grey; the disk with two obtuse tubercles. Elytra grey mixed with fulvous; each, between the middle and apex, bears an elongate dark brown spot, the anterior end of which is somewhat broader and turned in obliquely towards the suture. The legs are clothed with a fulvous-brown pubescence on the upper, and with a cinereous pubescence on the underside. This species may be recognized by its rather narrow form , its dorsally tubercled prothorax, its posteriorly gradually decli- vous elytra; and especially by the two post-median dark brown 104 Cc. J.
