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 an- 

 terior 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 my 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 yellow- 

 ish. 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 my examples, to be alike in both sexes. M. J. Thomson 

 places this genus in his " sous-tribe Callichromitce," notwithstand- 

 ing that the anterior acetabula are strongly angulated.

Deuteromma testaceum, Pascoe, op. cit. p. 111. 



To the short characters given in the above work, it is only neces- 

 sary 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 setacece, 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, unfor- 

 tunately, absent, it being, like many others of its subfamily, a fragile 

 species.
