Show 594 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Nov. 16, and the apex of the elytra metallic rufo-aureous, margined with green. Length 4 lines. Upper part of the head rufo-aureous, remotely and deeply punctate, lower part metallic bluish green, more finely punctate, labrum and the four basal joints of the antennse fulvous, rest of the joints black. Thorax long for this genus, about twice as long as broad, the anterior margin straight, the sides evenly rounded, all angles acute but not produced ; surface remotely but deeply punctate, intermixed with minute punctures, coloured like the upper part of the head, margined with metallic green ; scutellum pentagonal, smooth, of the latter colour. Elytra not wider at the base than the thorax, deeply punctate near the sides, finer and much more distantly towards the apex, the punctures at the latter placed regularly in double rows, otherwise confusedly arranged ; extreme apex brilliant metallic green, bordered with rufo-aureous above, but not extending to one third of the length of the elytra. This species is also found in the Amazonian region. Mus. Jacoby. Genus EUMOLPUS, Weber. 25. E U M O L P U S PRASINUS, Erichs. Amongst the normal-coloured specimens an entirely black variety has been collected, which, however, does not differ in other respects. 26. EUMOLPUS SURINAMENSIS, Fabr. Genus COLASPOIDES, Casteln. 27. C O L A S P O I D E S CUPREIPENNIS, sp. nov. Subrotundate, convex. Rufous ; last seven joints of the antennse black ; elytra greenish aureous, shining, finely punctate. Length 3 lines. Head impunctate ; clypeus separated from the front by a more or less triangular transverse groove; jaws black; antennse two thirds the length of the body, third joint one third longer than the fourth, four basal joints fulvous, the others black, rather compressed from the seventh joint. Thorax narrow, about three times as broad as long, the anterior margin not produced, sides rounded, fulvous, surface smooth, impunctate. Scutellum subtriangular, impunctate, seneous or purplish. Elytra convex, rounded towards the apex, obsoletely obliquely depressed round the humeral callus; surface finely semipunctate-striate, the punctuation not very closely placed, dark greenish or purplish seneous. Underside and the legs entirely rufous. Closely allied to C. bicolor, Oliv., but distinguished by the colour of the elytra, which is blue in this species; it may, however, be but a local variety of that insect. Mus. Godman and Salvin. |
