Show 1866.] MR. F. P. PASCOE O N T H E COLEOPTERA O F PENANG. 249 perhaps in habit and colour it is most suggestive of some species Phryneta (e. g. P. carca) ; but its cicatricose antennae will not permit it to be placed near that genus. For the present I should be inclined to put it after the African genera Imalmus and Hagesata. METOPIDES OCCIPITALIS. (PI. XXVII. fig. 5.) M. fuscus, pube densissima cervina tectus, vertice nigro signata. Dark brown, covered with a very close fawn-coloured pubescence ; head rugosely punctured in front, no median line, the vertex velvet-black, bordered at the sides and spotted in the middle with ochra-ceous ; prothorax deeply punctured, the intervals irregularly convex, sulcated behind, a black line at the apex and a black spot at the base; scutellum subscutiform, black in the middle ; elytra finely and irregularly punctured, with a few small granules at the base, two black spots on each side the scutellum, and an irregular mass of spots behind the middle mixed with a few white specks ; body beneath, legs, scape, and second joint of the antennae densely pubescent, somewhat darker than the elytra, &c, with larger snowy-white setulose hairs scattered over them, rest of the antennae with a thin greyish pubescence. Length 11 lines. EPEPEOTES. Antennae graciles, art. tertio scapo duplo vel triplo longiore. Pedes antici elongati; protibiae curvatar. Mesosternum elevatum, productum. Head exserted, subtransverse in front; antennary tubers robust, approximate at the base; eyes large. Antennae very long in the males, the scape not produced at the apex, the third joint two or three times as long as the scape, the following shorter and more or less equal, the last sometimes the longest of all. Prothorax trans- • verse, the propectus produced. Fore legs elongate, the tibiae curved, not toothed, their tarsi with the basal joint spined externally in the males. Mesosternum elevated, produced or keeled in front. Separated from Monochamus for the reception of those species which differ chiefly in a strongly produced mesosternum, the other characters being mostly those of that genus as it is here restricted. The type is Lamia lusca, Fab. EPEPEOTES LUSCUS. Lamia lusca, Fabricius, Ent. Syst. t. i. pt. 11. p. 283. Besides Siam, Malacca, and Borneo, this well-known species extends through Sumatra and Java to Timor. BLEPEPHJSUS. Antennae suUncrassatar, art. tertio quam scapus vix longiore: art. ult. pr arc. fere arquali. Propectus abbreviatum. Pedes antici carteris haud longiores. Mesosternum elevatum, dentatum. PROC. ZOOL.
