Show 1 882.] SPECIES OF PHYTOPHAGOUS COLEOPTERA, 55 interstices transversely wrinkled and costate near the apex; the interior of the punctures, especially near the lateral and sutural margins, metallic green. Underside and legs fulvous, closely covered with fine silvery pubescence. In m y collection. C H E I R I D E A , Baly. 8. C H E I R I D E A S U B R U G O S A , sp. nov. Oblong, convex, metallic green, pubescent. Legs cupreous. Thorax deeply punctate, its sides serrate. Elytra punctate-striate and transversely rugose, subpubescent, metallic green, with a broad transverse black band at the middle. Length 4 lines. Hab. Cameroons. Head rugose punctate, thinly covered with long white hairs, Labrum and jaws, as well as the palpi, black. Antenna? nearly half the length of the body, the joints robust and (with the exception of the first three joints) elongate, black. Thorax subquadrate, its sides slightly rounded and serrate, all the angles acute ; surface deeply and rather closely punctured, the interstices laterally transversely wrinkled; metallic green, covered with thin white hairs at the sides. Scutellum pentagonal, thickly covered with white pubescence. Elytra wider than the thorax, convex at the middle and acutely pointed at the apex, irregularly transversely rugose and deeply punctured, the interstices subcostate at the disk, metallic green, this colour divided at the middle of each elytron by a broad transverse black band which does not quite reach the suture, this band is limited anteriorly and posteriorly by thick white pubescence, which is also prominent towards the apex in the shape of longitudinal striae, principally near the sutural margin. Underside obscure metallic green, closely pubescent. Legs cupreous, femora without tooth. Claws appendiculate. In m y collection. This handsome species bears a close resemblance to Pseudocolaspis timialithus, Thorns., in regard to shape and colour, and might be easily mistaken for that species if the generic characters were not totally different. The serrate sides of the thorax, filiform antennae, and the appendiculate claw show it, however, to belong to Baly's genus Cheiridia, described in the Journ.Linn. Soc, Zool. vol. xiv. p. 253. HALTICID^E. DIAMPHIDIA, Gerstacker. 9. DIAMPHIDIA ANGOLENSIS, sp. nov. Broadly ovate, convex, testaceous or flavous. Antennae simple, black ; sides of the breast, knees, tibiae and tarsi, three spots on the head, and five on the thorax black ; elytra very closely punctured, black, sutural and lateral margins and a pear-shaped spot from the base to the middle flavous. Length 4|-5 lines. Hab. Angola (Africa). |
