Show 1894.] COLEOPTERA OF THE GENUS CEPIONYCHIS. 617 stripes have been described, principally by von Harold, but I am not able to identify with either of them the present species, which perhaps is most nearly allied to (E. inconstans, Schauf., and (E. formosa, Har.; none of these or others have, however, three longitudinal stripes on each elytron besides the sutural one as is the case in (E. osculans; there are besides this other differences which must be compared in the descriptions; m y specimen agrees entirely with the one contained in the British M u s e u m and which served Clark for his type. GilnioNYCHis INTERSIGNATA, n. sp. (Chevr. in litt.). Very convex, black; thorax impunctate, the sides flavous; elytra very finely punctured, metallic violaceous, a transverse band at the middle, not extending to the suture, and a spot at the apex flavous. Length 3£ lines. Head black, impunctate, shining; the antennae extending only to the base of the thorax, black, the third joint shorter than the fourth; thorax more than twice as broad as long, the sides strongly rounded, the anterior angles tuberculiform, the surface impunctate, shining, black, the sides as far as the flattened portion flavous ; scutellum black ; elytra very convex, finely and closely punctured, of a dark purplish violaceous colour, a broad transverse band at the middle, interrupted by the suture, and a subtriangular spot at the apex bright flavous; epipleurae violaceous within, flavous at their outer margin ; underside and legs black, shining. Hab. Surinam. Not unlike (E. libentina, Germ., in coloration, but larger, more convex, the elytral band much narrower and not extending to the suture. GIPIONYCHIS OBLONGA (Clk. Catal.) Fulvous, the apical joints of the antennae black; thorax impunctate ; elytra fulvous, impunctate, a broad transverse band at the base and another below the middle, not extending to the sides, violaceous blue. Length 3 lines. Head entirely impunctate, fulvous, the frontal elevations not strongly raised, carina short and thick; antennae extending to the middle of the elytra, the lower four or five joints fulvous, the others nearly black, fourth joint very elongate, slightly longer than the fifth, third joint scarcely half the length of the fourth; thorax about twice and a half broader than long, the sides rather evenly rounded, with the usual flattened margins, the surface entirely impunctate, with a narrow transverse impressed line or sulcus near the base, anterior angles rather acutely pointed; scutellum fulvous; elytra pale fulvous, entirely impunctate, the base with a broad transverse violaceous band extending nearly to the middle but not to the sides, the posterior margin of this band obliquely rounded at the latter place, a similar band is placed below the middle, the outer margins of this band are also rounded |
