Show 1899.] PHYTOPHAGOUS COLEOPTERA OF AFRICA. 365 thorax stronglv punctured ; elytra metallic dark blue, strongly punctate-striate, the interstices longitudinally costate. Length 2^ millim. Very closely allied to the preceding species, but apparently distinct; the head with some strong punctures anteriorly, the third joint of the antenna3 longer, the thorax much less transverse and convex, only about one-half broader than long, the surface very deeply but not very closely punctured ; the elytra as in the preceding species; the entire underside and legs fulvous. Hab. Cameroons. Beceived from Dr. Kraatz. The above-mentioned differences are, I think, sufficient to separate this species, and are probably not sexual, although I haA*e only a single specimen before m e ; the structure and sculpture of the thorax differ too much to allow the insect to be united to P. costatipennis, Avith which it otherwise agrees in generic details. APOPHYLIA MARGINATA, sp. n. Fulvous, the upper portion of the head metallic greenish or blue, thorax Avith three or four bluish spots ; elytra dark blue, finely transversely wrinkled, the lateral and apical margins fulvous, breast black. Var. Underside black. Length 6 millim. Upper portion of the head finely punctured, dark blue Avith two fulvous spots or entirely blue, frontal elevations narrowly transverse, lower portion fulvous or flavous; antennas extending to about the middle of the elytra, fulvous, the apex of each joint stained with fuscous, the terminal three or four joints entirely of that colour, third joint shorter than the fourth; thorax twice as > broad as long, tbe sides rounded, the anterior angles slightly thickened, the posterior ones oblique and rather indistinct, the surface finely and closely punctured and partly rugose, Avith some obsolete depressions anteriorly ; the disc fulvous, Avith three bluish spots, the middle one in shape of a V or separated into three smaller spots placed triangularly ; scutellum black ; elytra finely transversely wrinkled, the interstices finely punctured, dark blue, the lateral margin and the apical one more broadly fulvous, their epipleuras bread anteriorly, very uarroAved below the middle; the breast and the abdomen black, finely pubescent, or the breast only of that colour ; the legs fulvous, the third joint of the tarsi fuscous, the first joint as long as the following joints together; anterior coxal cavities open. Hab. Natal, on willoAV (G. Marshall). This species seems allied in coloration to A. nobilitata Gerst., but differs in having the entire upper portion of the head green as well as in the colour of the underside and some other details. A. consanguinea Alld. is described as having a green longitudinal thoracic band, also with three asneous spots on the vertex. |
