Show 1902.] OF AMERICAN COLEOPTERA. 197 tellum ; the disc impunctate, testaceous, very obsoletely transversely sulcate near the base ; scutellum black, margined with testaceous; elytra rather broadly ovate, impunctate, with a broad sutural and a very narrow sublateral black band, the disc with another broad band not quite extending to the apex, their epipleurae testaceous, black at their inner portion near the base ; below and the legs testaceous, the tibiae and tarsi blackish. Hab. Peru. Shorter and broader than Disonycha elongata, the sutural band much wider and the antennae and legs differently coloured ; the thorax is also more transverse in shape and the posterior angles less obliquely cut; the elytral pattern resembles entirely that of many species of Disonycha, but the eyes are distinctly reniform and the thorax is of different shape. NEPHRICA NIGROFASCIATA, sp. n. Black, the apical joints of the antennae and the legs flavous; thorax impunctate, flavous ; elytra very closely and distinctly punctured, black, a subsutural and a sublateral narrow band, connected at the apex, flavous, apex of the posterior femora black. Length 8 millim. Head black, shining, impunctate, with the exception of a few punctures near the eyes, the latter very large, reniform; antennae with the basal and the last four joints flavous, the others black; thorax twice as broad as long, the sides straight, the angles obliquely truncate, the surface flavous, impunctate; elytra closely, strongly, and irregularly punctured, flavous, the sutural and lateral margins narrowly black, the disc occupied by a broad longitudinal band which does not extend to the apex; below black, the femora and tibiae flavous, the apex of the posterior femora and all the tarsi black. Hab. Espirito Santo, Brazil. A large species, easy of recognition on account of the colour of the antennae and strong elytral punctuation, and resembling much a species of Disonycha, from which the shape of the eyes will distinguish it; the basal margin of the thorax is scarcely oblique at the posterior angles and altogether different in shape than in Disonycha. NEPHRICA UNIFASCIATA, sp. n. (Plate XX. fig. 7.) Black, the thorax fulvous, impunctate, obsoletely sulcate; elytra black, shining and impunctate, a round spot at the base of each and a transverse band near the apex white; abdomen fulvous. Length 6 millim. Head black, with a single deep puncture near the eyes, the latter large, reniform, frontal tubercles obsolete, carina strongly raised ; antennae black, the second and third joints small, nearly equal, the fourth elongate; thorax scarcely twice as broad |
