1866.] MR. F. P. PASCOK ON THE COLEOI'TERA OF PENANG. 241 



prothorace plagis duabus basalihus, scutelloque medio purpureo- 

 fuscis; tarsisfuscis. 



Dark brown, covered with a coarse yellowish-grey pile ; head 

 white between the eyes, the vertex with two purplish-brown spots ; 

 prothorax transverse, a large purplish-brown spot on each side ex- 

 tending to the base ; scutellum triangular, with a dark-brown central 

 spot ; elytra subtrigonate, strongly crested at the base, three well- 

 marked raised lines on each, across the middle, and curving round 

 from the shoulders a broad band paler and less pubescent than the 

 base and apex ; body beneath pilose, yellowish grey, the abdomen 

 ashy ; legs closely covered with a yellowish-grey pubescence, the 

 tarsi dark brown, with a fcv? scattered hairs ; antennae yellowish 

 brown. Length 6 lines. 



This description is from a specimen in my own collection, taken 

 by Captain Smythe of II. M. 34th ; Mr. Lamb's example is smaller 

 and much injured. It is a very distinct species, and will stand for 

 the present after Praonetha scopulifera, Pasc. 



Praonetha vixlosa. 



P. fusca, brunneo-griseo pubescens ; prothorace bitubercidato ; 

 scutello triangularis elytris obscure fusco variis, linea curvata 

 alba ante cristam posticam sita, crista antica nigro pilosa, 

 apicibus rotundatis. 



Dark brown, with a pale brownish-grey pile, and numerous fine 

 erect hairs ; head with a few punctures in front, antennary tubers 

 strongly marked ; prothorax subtransverse, the disk slightly bituber- 

 culate, with numerous small punctures ; scutellum triangular ; elytra 

 slightly subtrigonate, rather coarsely punctured, compressed, the 

 basal crests formed of black erect hairs, a short curved white trans- 

 verse line before the posterior crests, rest of the elytra obscurely 

 varied with brown ; body beneath and legs rufous, with a thin grey 

 pile ; antennas brown, slightly annulate with grey. Length 4 lines. 



This species will stand in my fifth section of the genus, after P. 

 fractilinea, characterized by the " elytra abruptly declivous poste- 

 riorly, the angle generally furnished with a short tuft (of hair) — 

 the exterior raised lines nearly obsolete." There are two or three 

 other species in the collection, which appear to be distinct from any 

 of the fifty-three species described in the ' Longicornia Malayans. 3
