Show 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 longitudinal 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 G. mathematica, but with the head and prothorax entirely unicolorous. The description is taken from one in Mr. Wallace's collection. In Mr. Lamb's example there is also a narrow greyish stripe on the brown portion of the elytron, &c. GLENEA ALYSSON. (PL 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 M r . Wallace's specimens taken at Singapore. GLENEA CEME. (PL XXVIII. fig. 2.) G. capite prothoraceque niveis, illo vertice nigro, hoc vittis duabus nigris ; elytris testaceo-brunneis, pube sparsa albida tectis ; antennis pedibusque testaceis, Ulis 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. GLENEA ILLUMINATA. Stibara illuminata, J. Thomson, Arch, Entom. i. p. 144. |
