Show 218 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, flavous, the others black; thorax rather strongly widened at tbe middle, extremely minutely and rather sparingly punctured, only visible under a strong lens, the sides feebly rounded, the posterior margin with some strongly marked teeth near the angles and preceded by a deep subquadrate fovea-the disc either black, with the anterior margin narrowly, the sides more broadly and. angularly flavous, and a similar coloured spot at the middle of the base (mas.): or flavous, with a broad anteriorly divided band, not extending to the margins, on each side, and the margins themselves narrowly, black (fern.) ; scutellum black; elytra very slightly narrowed posteriorly, regularly and strongly punctate-striate, flavous, rather opaque in the male, more shining in the other sex, the shoulders with an elongate black spot, a smaller one of rounded shape is placed near the scutellum, and two subquadrate spots, which are joined together anteriorly, below the middle, the sutural and apical margins are likewise narrowly black ; the underside and the femora black ; tibiae robust and widened anteriorly, fulvous, the outer margin of the anterior tibiae and the base of the four posterior black, tarsi fulvous ; prosternum prolonged laterally at the base into points, flavous, the apex of the mesosternum and a spot between the posterior coxae likewise flavous. Hab. Salisbury, Mashonaland, on mimosa (67. Marshall). The markings of the elytra resemble somewhat those of C. erythro-melas Suffr. and some other African species, but the shape of the posterior angular band is quite different; nor do I know of a similar structure in regard to the thorax, in w7hich the lateral basal teeth are preceded by a distinct notch or fovea; the shape of the prosternum with its prolonged posterior angles is another peculiarity of this species, of which I have three specimens before me. CffiNOBIUS PLAGIATUS, sp. n. Black, the antennae and the legs flavous ; thorax impunctate, black, the anterior and lateral margins and two basal spots flavous ; elytra very finely punctate-striate, black, a broad transverse baud before the middle and another at the apex flavous. Length \\ millim. Of narrow, cylindrical shape ; the head black, impunctate, the eyes widely separated, not strongly emarginate, parts of the mouth and the antennae flavous, the latter short, with the sixth and the following two joints strongly dilated (the rest wanting); thorax twice as broad as long, the sides feebly rounded, narrowed towards the apex, the surface impunctate, black, very shining, the anterior margin very narrowly and the lateral ones more broadly flavous, the base with two other bright flavous transverse spots, only separated by a thin stripe of the grouud-colour; scutellum broad, pointed at the apex, black ; elytra not wider at the base than the thorax, scarcely perceptibly punctate-striate, the striae widely separated, the black portion divided by a broad transverse bright flavous band, which surrounds the shoulders at the outer margin and does not quite extend to the suture, this band is placed before |
