costa, commencing between the eyes and terminating- at the apex 

 in the form of a narrow triangle, apical half of sides flattened, 

 glabrous and with sparser punctures than elsewhere. Scrobes 

 deep and curved aibout antennae, but disappearing half-way be- 

 tween them and eyes. With feeble sublateral sulci. Antennae 

 short ; first joint of funicle distinctly longer than second, second 

 longer than third, fourth-sixth sub-globular, seventh feebly trans- 

 verse. Prothorax transverse, convex, sides evenly rounded ex- 

 cept at almost extreme base and apex, usually with a feeble 

 median impunctate line ; punctures as on head. Scutellum 

 small but distinct. Elytra elongate — subcordate, conjointly 

 arcuate at base, with rows of fairly large but usually concealed 

 jDunctures ; interstices gently convex, the alternate ones very 

 feebly raised, with dense and very small punctures. Under sur- 

 face with small and dense punctures. Legs rather long ; front 

 tibiae denticulate below. Length (excluding rostrum), 8^ — 10|^ 

 mm. 



The male differs from the female in being smaller, with 

 narrower and more parallel-sided elytra and longer legs. 



The acutely carinated rostrum and first joint of funicle de- 

 cidedly longer than the second readily distinguish from most 

 previously described species of Perperus ; the sides of the ros- 

 trum in front are reminiscent of Rhinaria. In some specimens 

 (usually females) the derm is entirely of a dark reddish brown. 

 The scales are so readily abraded that the disc of the prothorax 

 usually appears to be> glabrous, and on the elytra large irregular 

 patches are frequently denuded ; on the elytra the scales fre- 

 quently have a golden gloss ; on them also they aa-e everywhere 

 dense, but they are rather denser on the odd than the even 

 interstices. On the upper surface the scales are more numerous 

 than the setae, but the reverse is the case on the under surface 

 and legs. Tho hind femora are usiuilly feebly ringed, and traces 

 of still more feeble rings cam sometimes be seen on the others.
