Show 240 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8 cent, scarcely fimbriated; scape obconic, third joint much longer than the fourth, the rest very short. Prothorax a little broader than the head, subcylindrical, toothed anteriorly. Elytra elongate, cylindrical, callous at the base. Legs short, equal; anterior tibiae not toothed internally. Presternum elevated. Mesosternum toothed anteriorly. The presence of a prothoracic tooth, as well as the style of sculpture, places this genus in the neighbourhood of Synelasma, from which, however, it abundantly differs in the characters of the head, antennae, and in its elongate cylindrical form. CYARDIUM CRIBROSUM. (PI. XXVI. fig. 5.) C. pallide fer rugineum, sparse griseo pub esc ens ; elytris post medium fascia albida ornatis ; antennis articulis tertio et quarto, apice excepto, albis. Pale rusty brown, rather sparingly clothed with a greyish pubescence ; head deeply impressed on the vertex between the upper lobes of the eyes, the front coarsely punctured, each puncture with a stiff whitish hair at the base; prothorax with deep crowded irregular impressions having apparently a deciduous greyish pubescence, the raised intermediate portions tuberculiform or granular; scutellum very transverse; elytra with a slight callus near the base, and numerous large foveolate punctures, and little patches of ochreous pubescence between them, behind the middle a broad whitish band; body beneath pale buff, spotted with yellowish brown; legs buff, varied with brownish ; antennae dark brown, the scape reddish brown, third and fourth joints white except at their tips. Length 8 lines. SESIOSA. Sesiosa, Pascoe, Long. Malay, p. 154. SESIOSA SUBFASCIATA, Pascoe, I. c. p. 154, pi. 8. f. 2. The Wallacean specimen is from Singapore. The genus is allied to Apomecyna. PRAONETHA. Prioneta (ab errore), Blanchard, Voy. au Pole Sud, iv. p. 292. PRAONETHA OBDUCTA, Pascoe, Long. Malay, p. 165. The puncturation is a little coarser than on the typical specimens from Ceram and Bouru, on which I have based m y description. PRAONETHA ILLICITA, Pascoe, I. c. p. 169. It is possible that this is only a subspecies or variety of a widely distributed species, and it will then be found to extend from Penang to Java on the one hand, and to A m on the other. Other localities are Goram, Batchian, and Mysol. PRAONETHA CONSULARIS. P. fusca, pube densa flavida vestita; vertice maculis duabus, |
