Show 230 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8, CUPHISIA CALLOSA. (PI. XXVI. fig. 1.) C. pallide fusca, sparse griseo pubescens ; elylris fortiter punc-tatis, basi fulvis, maculis paucis fulvo pilosis ornatis. Pale brown, subnitid, with a sparse greyish pubescence ; head and prothorax reddish brown, impunctate, the pubescence thicker, with a yellowish tinge ; scutellum nearly triangular, pointed posteriorly; elytra coarsely substriate-punctate, the base fulvous, and having a well-marked callus on each near the suture and a little behind the scutellum, posteriorly four patches of fulvous hairs, one behind the middle, equidistant from the suture and external margin, another and the largest preapical, and two outer on the same lateral lines as the preceding; body beneath, legs, and antennae more or less fulvous brown, subnitid, and all, as well as the whole upper surface, clothed with scattered erect setose hairs, principally white, but intermixed with a few black. Length 2\ lines. NlPHONlN^E. ^ELARA. AElara, J. Thomson, Syst. Ceramb. p. 55. JELARA ARROGANS. Niphona arrogans, Pascoe, Journ. of Entom. i. p. 338. Mlara arrogans, Pascoe, Long. Malay, p. 82, pi. 4. f. 5. M . Thomson has two other genera (Camptocnema and Ocheutes) which I am unable to distinguish satisfactorily from this. The comparative length of the antennae, upon which they appear to be chiefly based, varies according to the species and to the sex : thus the male of AElara arrogans, which is an Ocheutes, has the antennae quite as long as AZ. excisa, which I take to be congeneric with M. ferdinandi, the type of the genus. Neither of the three genera would admit Niphona cylindracea, White; and one or two others would be nearly as difficult to locate. At the same time they are all tolerably homogeneous in appearance. The species under review has been taken by Mr. Wallace in Sarawak, where it does not appear to be uncommon. ^ELARA CONCISA, Thomson. I have received a specimen from M . J. Thomson under this name from Java. I am not aware if he has published it. I have seen it, or a species very similar, from the Himalaya, in Mr. W . Wilson Saunders's collection. DAXATA. Daxata, Pascoe, Long. Malay, p. 88. DAXATA USTULATA. (PI. XXVII. fig. 4.) D. grisescens, maculis punctiformibus nigris ornata ; elytris singulis basi lineato-cristatis. |
