Show 428 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, the breast piceous; thorax impunctate; elytra subdepressed, extremely closely and finely punctured, the basal margin, a narrow transverse band below the middle, and two spots near the scutellum dark brown. Length 7 millim. Head impunctate, testaceous, the frontal elevations rather feeble ; eyes large, the intermediate space not wider than the width of each eye; antennae with the basal three or four joints and the apical one testaceous, the rest blackish; thorax short and transverse, the sides broadly flattened, the anterior angles dentiform ; the disc impunctate, testaceous, feebly transversely sulcate near the base ; scutellum testaceous ; elytra widened towards the apex, rather flat, extremely finely and closely punctured, testaceous, the extreme basal margin, a small spot near the scutellum, and a narrow transverse, slightly convex band, immediately below the middle, piceous or dark fulvous ; legs testaceous; breast and abdomen piceous. Hab. Pichinclie, Colombia (Rosenberg). Of this species I have five exactly similar specimens before me. The design of the elytra differs from that of any other species I am acquainted with except 0. tenuicincta Jac., which is a differently shaped insect, with a different thorax, very narrow elytral bands, and of black colour. This species is also known from Mexico. O ed io n y ch is d iv e r sa , sp. n. Testaceous, the apical joints of the antenna? (except the last) and the breast black ; thorax impunctate ; elytra elongate, finely punctured, each with two spots at the base, one at the middle, and a transverse band near the apex, black. Var. The apical band divided into two spots. Length 5 millim. Head impunctate, deeply foveolate between the eyes, the latter very large ; antennae with the lower five and the apical joint testaceous, the others black, third and fourth joints equal, elongate, the terminal joints rather shorter; thorax about twice and a half broader than long, the sides broadly flattened, the lateral margins strongly rounded anteriorly, the anterior angles thickened but not produced, the surface impunctate, rather convex ; scutellum black; elytra elongate, nearly parallel, very minutely punctured, testaceous, a small spot on the shoulders, another near the scutellum, a third at the middle, and a transverse band near the apex, not quite extending to either margin, black ; legs and abdomen testaceous, breast black. Hab. St. Catharina, Rio Janeiro, Brazil. A somewhat elongate species, principally distinguished from those with similar elytral spots by the additional black subapical band and the black breast, colour of the antennae, &c.
