1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 511 

 ClOPERA DECOLORATA. (PI. XLI. fig. 10.) 



C. testacea, subtiliter pubescens ; femoribus tibiisque basi in/us- 

 catis. 



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 ante- 

 riorly ; scutellum oblong, narrow; elytra finely punctured, the 

 punctures finer and more dispersed posteriorly, apices slightly de- 

 hiscent and pointed ; body beneath pale testaceous ; legs testaceous, 

 the femora and bases of the tibiae brownish ; antennae slight pdose. 

 Length 6 lines. 



RhINOTRAGINjE. 



Epianthe. 



Antennae apicem versus incrassatce, scapo obconico. 

 Elytra Integra, parallela. 

 Tarsi postici elongati. 



Head not elongate anteriorly, slightly constricted behind, the 

 forehead rather broad. Eyes narrowly emarginate, lateral, not ap- 

 proximate 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 con- 

 stricted near the base and apex. Elytra flattish, entire, nearly pa- 

 rallel 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 Rhinotragince was known from Asia until M. 

 J. Thomson published his three genera Plutonesth.es, Artimpaza, 

 and Gleomenes ; four more are here added, all very distinct from 

 one another. These are all confined to single examples. Mr. Wal- 

 lace's collections, too, contained but two specimens, each represent- 

 ing 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. (PI. XLI. fig. 5.) 

 E. viridi-metallica ; pedibus anticis rufis.
