Show 1894.] COLEOPTERA OF THE GENUS CEPIONYCH1S. 621 not be safe to say; this specimen agrees otherwise with those from the Amazons, but has a black underside and legs, beside the other difference pointed out. OZPIONYCHIS SEMIPIVISA, n. sp. Flavous, the base of the head black, antennae and legs dark fulvous, thorax impunctate ; elytra closely and finely punctured, a subquadrate patch at the base and a more elongate one, more or less indented at the posterior portion, dark violaceous. Length 2|-3 lines. Head with a few punctures near the eyes, the vertex black, the margin in front of the eyes and the clypeus flavous, labrum black; antennae extending nearly to the middle of the elytra, dark fulvous, the third and fourth joints equal; thorax three times broader than long, flavous, the sides rounded, the anterior angles slightly produced outwards, the surface rather convex, flavous, shining; scutellum black ; elytra very closely and finely punctured, flavous, a large subquadrate patch at the base not extending to either margin and indented at its anterior margin at the shoulders, violaceous black, this patch is followed immediately below the middle by a similar but a more elongate patch, which is sometimes strongly constricted at the middle, or if entire encloses a small spot of the ground-colour. Hab. Peru. From other nearly similarly coloured species the present one may be distinguished by the shape of the elytral markings, the anterior one of which shows a short encroachment of the ground-colour near the shoulders, and the posterior mark a semi-division at the middle in one specimen or an inclination to divide in the other. I believe that the shape of these markings and their dark violaceous colour constitute a specific distinction ; none of the dark patches quite extend to either margin, but are divided at the middle by a very narrow band of the ground-colour. The species seems allied to (E. biloba, Illig. ffiniONYCHIS JAMAICENSIS, n. Sp. Flavous; antennae robust, thorax strongly transverse, impunctate; elytra entirely impunctate, metallic violaceous blue. Length 4 lines. Head impunctate, flavous, shining, depressed between the eyes, the frontal elevations obsolete ; palpi strongly thickened ; antennae robust, flavous, the third and fourth joints nearly equal; terminal joints slightly darker ; thorax nearly four times broader than long, the sides strongly rounded, the anterior angles strongly thickened, but not produced, the sides with a comparatively narrow flattened margin, the surface shining, impunctate; elytra convex, with a short obsolete depression below the base, strongly convex, entirely impunctate, of a bright metallic violaceous colour; underside and legs flavous. Hab. Jamaica. |
