Violaceous-blue, the antennae, tibiae, and tarsi black; the femora cupreous ; thorax subclyindrical, closely and strongly punctured ; elytra punctured like the thorax, with rows of very short, white hairs, distantly placed. Length 4 millim. • Head coarsely and closely punctured, dark blue; the antennae entirely black, the terminal five joints strongly dilated, club-shaped; thorax scarcely broader than long, narrowed anteriorly and to a less extent near the base ; the entire surface closely and strongly punctured, the punctures round and deep, the middle with a more or less distinct narrow, raised longitudinal space; scutellum subquadrate, its apex truncate, the posterior angles feebly produced, the base with two or three deep punctures ; elytra with the shoulders prominent and acute, not depressed below the base, punctured like the thorax, but the punctures rather more closely placed and the interstices finely transversely rugose, sparingly furnished with very short stiff whitish hairs; legs coarsely punctured ; the femora with a strong acute tooth, cupreous; the intermediate tibiae, with the exception of the extreme apex which is more or less cupreous, black ; claw-joint very long and slender. Hab. Salisbury, Mashonaland, obtained by sweeping (67. Marshall). Distinct from all its numerous African allies by its uniform dark blue colour and the cupreous femora, in connection with the strong punctation of its upper surface. PSEUDOCOLASPIS SEVERINI, sp. n. Black, sparingly pubescent,thorax finely and closely punctured; elytra finely punctured in semiregular rows near the apex, the interstices clothed with very short, erect, silvery hairs. Length 4 millim. Head closely and rather strongly punctured; clypeus broad, subquadrate, scarcely punctured ; antennae black, the lower four or five joints more or less piceous; the second and the following two joints very short, mouiliform, the terminal ones strongly thickened and robust, the last longer than broad; thorax rather long, subcylindrical, but slightly narrowed in front, the surface without any perceptible sulci or depressions, closely and strongly puuctured, with a smooth narrow middle line; scutellum broad, subpentagonal, impunctate; elytra narrowed posteriorly, not depressed below the base, the shoulders prominent, the surface closely, finely, and irregularly punctured, the punctures slightly more regularly arranged in rows near the apex ; the interstices with single short silvery pubescence ; femora with a small tooth ; underside and legs rather strongly punctured. Hab. Moliro, Congo (J. Duvivier). (Coll. Brussels Mus. and my own.) There are not many entirely black species of Pseudocolaspis |
