Show 530 MR. M. JACOBY ON THE [May 18, Head finely and remotely punctured, with a short longitudinal central groove ; clypeus sparingly punctured, not separated from the face, its anterior margin nearly straight; labrum piceous; antennae slender, extending to about the middle of the elytra, black, tbe lower four joints and the base of the fifth fulvous, third joint slightly shorter than the fourth and fifth, which are equal; thorax one-half broader than long, the sides evenly rounded, not narrowed in front, the surface strongly and not very closely punctured, with a narrow smooth central space somewhat obsolete, posterior angles indistinct, the disc with a very obsolete depression at each side near the base; elytra very slightly widened towards the middle, strongly and closely punctured in rows, the interstices also finely but distinctly punctate, especially so near the base, those at the sides raised into two or three narrow costae; legs piceous, the extreme base of the femora and the anterior legs more or less fulvous. Hah. Mashonaland (67. Marshall). This insect agrees very nearly with L. puncticollis in regard to tbe punctuation of the elytra ; but the shape of the thorax and its sculpture are so different, that I cannot look upon it as identical, although it m a y represent the female sex of that species. In L. puncticollis the sides of the thorax are very strongly rounded and widened, and the disc is very closely and finely punctured: the opposite in regard to both these details is the case in the present species, examples of which are contained in the British Museum collection and in m y own. LEFEVREA MINUTA, n. sp. Below black, above dark green, basal joints of the antennae fulvous ; thorax extremely closely punctured ; elytra closely punctate-striate, the interstices minutely punctate. Length |-1 line. In shape resembling a small species of Colaspls; the head distinctly and closely punctured, the vertex more distantly so; sides of the clypeus thickened, the latter not separated from the face ; antennae not extending to the middle of the elytra, black, the lower four joints fulvous, third and fourth joints equal, second slightly shorter, terminal joints gradually thickened; thorax twice as broad as long, the sides very strongly rounded and widened at the middle, the surface extremely closely and rather strongly punctured; scutellum broader than long, with a few punctures; elytra parallel, not wider than the thorax, closely punctate-striate, each puncture provided with an extremely short hair, the interstices also closely punctured, those near the lateral margin slightly longitudinally costate: underside and legs blackish, nearly impu-bescent; prosternum strongly narrowed between the coxae. Hab. Niger-Benue Exped. (Staudinger). The smallest species of those here described ; the sides of the thorax very strongly rounded. I received several specimens from Dr. Staudinger. |
