1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 261 



Head, prothorax, scutellum, and broad stripe along the suturai 

 region covered with a dense greyish velvety pile, rest of the elytra 

 brown and glabrous ; head and prothorax remotely punctured, the 

 latter gradually narrowed posteriorly, the disk with a slight longi- 

 tudinal ridge ; elytra narrow, gradually tapering to the apex, the 

 glabrous brown portion only punctured, the apices obliquely emargi- 

 nate with a long mucro at the external angle ; body beneath greyish 

 pubescent ; antennae blackish brown ; legs brown, base of the femora 

 reddish; posterior tarsi greyish. Length 5 lines. 



Allied to 6?. mathematica, but with the head and prothorax en- 

 tirely unicolorous. The description is taken from one in Mr. Wal- 

 lace's collection. In Mr. Lamb's example there is also a narrow 

 greyish stripe on the brown portion of the elytron, &c. 



Glenea alysson. (PI. XXVIII. fig. 8.) 



G. capite prothoraceque fuscis, hoc et vertice in medio vitta 

 ochracea ; elytris brunneis, extus infuscatis, apice singulorum 

 macula nivea ornatis ; antennis nigris, articulis quatuor ulti- 

 mis albis. 



Head dark brown, a white line bordering the eye in front, the 

 vertex with an ochraceous spot continuous with a broad stripe of 

 the same colour on the prothorax ; cheeks, stripe on the side of the 

 prothorax, and all the under parts pale ashy ; scutellum ochraceous ; 

 elytra pale brown, the outer side darker, a snowy-white spot on each 

 at the base of the strongly marked exterior mucro ; legs testaceous, 

 the lower half of the posterior tibiae and their tarsi white ; antennae 

 black, the last four joints white. Length 5-6 lines. 



The colouring of the antennae and the absence of stripes on the 

 elytra will readily distinguish this species. The description is from 

 one of Mr. Wallace's specimens taken at Singapore. 



Glenea ceme. (PI. XXVIII. fig. 2.) 



G. capite prothoraceque niveis, Mo vertice nigro, hoc vittis duct- 

 bus nigris; elytris testaceo-brunneis, pube sparsa albida tectis ; 

 antennis pedibusque testaceis, Mis articulis duobus basalibus 

 nigris, articulo ultimo albo. 



Head and prothorax snowy white, the former with the vertex and 

 behind the eyes black, the latter with a broad black stripe on each 

 side ; scutellum large, subscutiform, white ; elytra rather short, 

 gradually tapering posteriorly, the outer angle of the apex strongly 

 mucronate, covered with a uniform thin whitish pile ; body beneath 

 reddish ferruginous, subglabrous, the sides with a dense snowy- 

 white pile ; legs testaceous ; antennae testaceous, the two basal joints 

 black, the last white. Length 4 lines. 



There is but one example of this species, but it is very distinct 

 from any other known to me.
