Show 510 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [Nov. 22, Head black, nearly impunctate; prothorax bright yellow, with five oblong raised elevations on the disk, and a raised transverse anterior line ; scutellum transversely subquadrate ; elytra nearly as long as the abdomen, rather suddenly narrowed behind the middle, finely seriate-punctate, testaceous, the outer portion from the shoulders to the apex black ; abdomen and postpectus black, antepectus yellow; legs black, femora at the base pale yellow. Length 4 lines. There are a number of undescribed species in m y collection ; it is therefore only necessary here to say that the nearest ally of this insect is M. scitella, which has much shorter elytra, not suddenly narrowed posteriorly, with the last two joints of its antennae yellowish. The males in this genus have longer and more slender antennae than the females; but the extraordinarily clavate posterior femora, and the strongly spurred tibiae of the same pair, appear, judging from m y examples, to be alike in both sexes. M. J. Thomson places this genus in his " sous-tribe Callichromitar," notwithstanding that the anterior acetabula are strongly angulated. OBRIIN^E. DEUTEROMMA. Deuteromma, Pascoe, Trans. Ent. Soc. ser. 2. iv. p. 98. DEUTEROMMA TESTACEUM, Pascoe, op. cit. p. 111. To the short characters given in the above work, it is only necessary to add here that this is well distinguished from three or four other entirely testaceous species, not yet described, by the dark brown colour of the two basal joints of the antennae. ClOPERA. Oculi fere integri. Antennae setacear, scapo cicatricoso. Prothorax elongatus. Head short and subtriangular in front, rather longer behind. Eyes oblong, nearly entire, prominent. Antennae setaceous, longer than the body ; the scape strongly cicatricose ; the third joint longer; the fourth shorter than the third ; the remainder longer than the third and subequal, or a little shorter towards the apex. Palpi with the terminal joint thicker, truncate. Prothorax elongate, not wider than the head. Elytra narrow, imperfectly embracing the abdomen at the sides. Legs slender; anterior shortest, posterior longest; femora thickened beyond the middle ; tarsi much shorter than their tibiae. Anterior coxae produced, subconical, their acetabula strongly angulated. A very distinct genus, like Deuteromma in habit, but with entire eyes, or in the slightest degree emarginate, and the scape with a strongly marked cicatricose apex. The posterior tarsi are, unfortunately, absent, it being, like many others of its subfamily, a fragile species. |
