Show 1894.] OOLEOPTERA OF THE GENUS CEPIONYOHIS. 623 Length 3 lines. Head black, the extreme base with a few punctures, the space surrounding the eyes and the sides of the clypeus flavous ; antennae not extending to the middle of the elytra, black, the lower three joints and the apical one obscure piceous ; thorax rather strongly convex, three times broader than long, the sides strongly rounded in front, the anterior angles not produced outwards, the sides with a broadly flattened margin, posterior margin sinuate at each side, the surface impunctate, flavous ; scutellum black; elytra very finely but not very closely punctured, with a double row of deeper punctures within the shoulders, black, the extreme and thickened lateral margin, as well as the epipleurae and a rouuded spot at the extreme apex, flavous; some rows of deeper punctures also accompany the lateral margin; underside and legs black ; sparingly pubescent. Hab. Brazil. Allied in coloration to (E. extrema, Har., from Mexico, but in that species the thorax has mucronate angles, the epipleurae within as well as the underside and legs are piceous, and the elytra are blue. EPIONYCHIS APICATA (Clk. Catal). (Plate XXXVIII. fig. 9.) Black, the sides of the thorax flavous, the surface impunctate ; elytra dark violaceous or purplish, impunctate, the apex with a round flavous spot. Length 3 lines. Head impunctate, black, shining, the frontal elevations entirely wanting, carina acute, palpi flavous ; the antennae not extending to the middle of the elytra, black, the first joint stained with fulvous, the apical one entirely of that colour, the second and third joints very short, subequal; thorax with the anterior margin deeply concave, the anterior angles very prominent but not produced outwards, the sides evenly rounded, the surface impunctate, black, shining, the sides broadly pale flavous ; scutellum black; elytra obscure metallic purplish or violaceous, impunctate, the apex of each elytron with a round flavous spot; underside and legs black. Hab. Brazil. This species may not only be recognized by its coloration, but by the absence of any frontal elevations on the head and by the short second and third joints of the antennae. EPIONYCHIS MOROSA, n. sp. Black, opaque, impunctate, thorax and elytra narrowly margined with flavous. Length 3 lines. Of a uniform black, opaque colour ; the head impunctate, the frontal tubercles narrowly transverse; the antennae black, short, the third and fourth joints equal; thorax twice as broad as long, the sides rounded in front, straight at the base, anterior angles produced forwards, without acute tooth, rather blunt, the surface |
