Show 354 MR. M. JACOBY ON T H E [Mar. 7, very closely and distinctly punctured ; elytra strongly punctate-striate, the interstices finely punctured, each elytron with a longitudinal fuscous band, abbreviated behind, and the apex fuscous. Length 4 millim. Of parallel shape ; the head impunctate, obsoletely sulcate in front of the eyes ; clypeus separated from the face by a transverse groove, rather deflexed, impunctate, palpi slender; antennas extending slightly beyond the base of the elytra, fulvous, the terminal four or five joints fuscous, the third joint slender, longer than the fourth one, terminal joints thickened; thorax twice as bread as long, the sides slightly and evenly rounded, the anterior angles slightly oblique but not produced, the basal margin with a short but deep longitudinal groove, tbe surface extremely closely and rather strongly punctured throughout; elytra Avith regular rows of strong punctures, closely placed, the interstices very finely punctured, fulvous, the extreme lateral margin, the apex in shape of a triangular spot, aud a narrow longitudinal stripe at the middle of each elytron nearly black, the latter abbreviated before the apex ; underside and legs fulvous. Hab. Niger-Benue Expedition (Staudinger). I have received two specimens of this very distinct species from Dr. Staudinger. NlSOTRA UNIFORMA, Sp. 11. Pale fulvous, the terminal joints of the antennas darker ; thorax finely and closely punctured, the basal sulci short and deep; elytra closely and finely punctured, the punctation partly geminate-striate. Length 3-4 millim. Head very finely and somewhat closely punctured, the clypeus with some stronger punctures ; the antennas nearly extending to tbe middle of the elytra, black, the loAver five or six joints fulvous, the third joint slightly longer and more slender than the following tAvo joints, terminal ones thickened; thorax more than twice as broad as long, the sides straight at the base, rounded at the middle, the anterior angles scarcely oblique or prominent, the perpendicular basal grooves short and deep, the disc rather convex, finely and rather closely punctured; elytra with closely approached double rows of fine punctures, more or less distinct; underside and legs pale fulvous. Hab. Sierra Leone, Bhobomp, Niger - Benue Expedition (Staudinger). Although this species seems very closely allied to N testacea Chap, and Ar. chapuisi Jac. from Madagascar, I think it sufficiently different to be considered distinct. N. testacea, of Avhich the description is scarcely detailed enough, is said to have a dark breast and abdomen, as well as similarly coloured posterior femora. |
