Show 1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 511 ClOPERA DECOLORATA. (PI. XLI. fig. 10.) C. testacea, subtiliter pubescens ; femoribus tibiisque basi infuscatis. Testaceous, a little darker anteriorly, covered with a loose delicate pubescence; head and prothorax minutely and closely punctured, a short median line between the antennae terminating in a semicircular impression above the mouth; prothorax slightly constricted anteriorly ; scutellum oblong, narrow; elytra finely punctured, the punctures finer and more dispersed posteriorly, apices slightly dehiscent and pointed; body beneath pale testaceous ; legs testaceous, the femora and bases of the tibiae brownish; antennae slight pilose. Length 6 lines. RHINOTRAGINJE. EPIANTHE. Antennae apicem versus incrassatar, scapo obconico. Elytra integra, parallela. Tarsi postici elongati. Head not elongate anteriorly, slightly constricted behind, the forehead rather broad. Eyes narrowly emarginate, lateral, not approximate above. Antennae thickened towards the apex, half as long as the body ; the scape short, obconical; the second joint half the length of the scape ; third longest of all; fourth, fifth, and sixth short; the last five shortest and forming a thickened continuous cylinder. Prothorax oblong, as broad as the head, slightly constricted near the base and apex. Elytra flatfish, entire, nearly parallel at the sides. Legs unequal; femora thickened towards the apex ; tibiae slender; posterior tarsi with the basal joint as long as the rest together. No member of the Rhinotraginar was known from Asia until M. J. Thomson published his three genera Plutonesthes, Artimpaza, and Cleomenes; four more are here added, all very distinct from one another. These are all confined to single examples. Mr. Wallace's collections, too, contained but two specimens, each representing a genus; one of them, however, is Artimpaza odontoceroides, J. Thomson. From the individual rarity of these insects it is very likely that the group in Tropical Asia is much more extensive than it appears to be at present. It is probable that, when more of the species shall be known, some modifications of the characters of the genera here given will be requisite, especially of the antennae. All the genera in Mr. Lamb's collection have the elytra entire-that is to say, neither shortened nor dehiscent at the suture, although, as in the subfamily generally, only imperfectly covering the abdomen at the sides. EPIANTHE VIRIDIS. (PL XLI. fig. 5.) E. viridi-metallica ; pedibus anticis rufis. |
