Show 592 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Nov. 16, account of the closer punctuation. Scutellum impunctate. Elytra very convex, very dark purplish, subopaque ; the punctuation not differing from that of the other parts, but closer and arranged in almost regular rows near the suture, more confused near the sides where a costa runs parallel with the lateral margin ; the apex of the tibiaa and the tarsi fulvous, rest of the legs dark brown. Mus. Jacoby. 17. COLASPIS CHLORITES, Erichs. 18. COLASPIS FULVILABRIS, sp. nov. Oblong. Below bluish black, shining; legs and antennse (three middle joints of the latter excepted) testaceous, labrum fulvous ; above dark violaceous ; sides of thorax one-toothed, deeply punctate. Length 4\ lines. Head with a distinct central groove ending in a shallow fovea, rather closely and deeply punctate; antennas testaceous, joints 6-8 piceous. Thorax convex, distinctly toothed at the middle of the lateral margin, in front of which the latter is widened ; anterior angles thickened, posterior ones acutely toothed ; surface distinctly foveolate at each side, deeply and irregularly punctured. Elytra convex, scarcely wider at the base than the thorax, punctured like the latter, but the punctures more evenly distributed ; interstices smooth except near the apex, where they are somewhat wrinkled. Underside shining, lead-coloured ; legs fulvous. Mus. Jacoby. 19. COLASPIS NIGRIPENNIS, sp. nov. Black, antennse and legs testaceous; thorax bisinuate at the sides, and, as well as the elytra, finely punctate. Length 4 lines. Head with deep oblong punctures between the eyes and a narrow longitudinal central groove ; clypeus and the vertex more sparingly punctate ; labrum fulvous ; antennse nearly as long as half the body, together with the palpi testaceous. Thorax transverse, convex, obsoletely bisinuate at the lateral margin, surface with a deep fovea at each side; surface distantly and finely punctate, the punctures near the sides deeper but not more closely placed, the interstices at the same place also very minutely punctured when seen under a strong glass. Scutellum finely longitudinally striate. Elytra parallel, moderately convex, punctured like the thorax, but more regularly striate, except near the lateral margin, where the puncturing becomes more confused. Underside black with a bluish tint, legs entirely testaceous. Mus. Jacoby. 20. COLASPIS FOVEICOLLIS, sp. nov. Greenish black below, above black, last four joints of the antennse and the legs testaceous ; thorax bidentate, deeply foveolate at the sides ; elytra finely subgeminate-punctate-striate. Length 3 lines. |
