Show 350 MR. M. JACOBY ON T H E [Mar. 7, apex, the second, half the length of the third, the others nearly ecpial in length ; thorax transverse, subquadrate, twice as bread as long, the sides very slightly rounded before the middle, the anterior angles oblique, not produced, posterior ones distinct, the surface with a narrow transverse sulcus, not quite extending to the lateral margins, the disc punctured like the head, fulvous, shining; scutellum fulvous ; elytra dark blue, the extreme sutural margin and the epipleuras fulvous, the disc strongly and closely longitudinally costate, each elytron with eight costas and another short subsutural one, the interstices transversely rugose-punctate: underside and the legs fulvous, posterior femora moderately incrassate, the first joint of the posterior tarsi as long as the following joints together ; prosternum narrow and strongly raised, the anterior coxal cavities closed. Hab. Zambi, Congo (coll. Belgian Mus. and m y own). This insect differs from typical species of Qrepidodera in the very narrow and strongly convex prosternum, also in the absence of a lateral perpendicular groove, which generally limits the transverse sulcation of the thorax; it should perhaps be placed in a separate genus. CREPIDODERA NATALENSIS, sp. n. Piceous, the antennas and legs flavous, above obscure asneous; thorax very finely and closely punctured, with deep basal sulcus and lateral grooves ; elytra finely punctate-striate, the interstices sparingly and minutely punctured. Length 3 millim. Head greenish asneous, entirely impunctate, with a short perpendicular groove immediately above the eyes, frontal elevations small ; the clypeus with an acutely raised central ridge; the antennas slender, flavous, the terminal joint stained with fuscous, the second joint scarcely shorter than the third, the terminal four joiuts slightly thickened; thorax about one-half broader than long, the sides straight at the base, rounded before tbe middle, the angles distinct but not acute, the surface very closely and finely punctured, greenish asneous, the basal sulcus very deep and bounded laterally by an equally deep longitudinal groove, Avhich extends upwards some little distance, the basal portion behind the sulcus of more distinctly fulvous colour and likeAvise finely punctured; elytra elongate and convex, the apex rather pointed, the basal portion very feebly depressed, the disc rather strongly and very regularly punctate-striate, of the same colour as the thorax, the interstices very finely punctured; below and the legs flavous, the apex of the posterior femora more or less stained with piceous. Hab. Estcourt, Natal (67. Marshall) ; also Dunbrody, S. Africa (Rev. T. O'Neil). This little species must be closely allied to C. tosta Gerst. in regard to its obscure asneous coloration, but the impunctate head, very closely punctured thorax, and its distinct transverse basal sulcus prevent the insect being identified with the last-named |
