Show 1885.] PHYTOPHAGOUS COLEOPTERA. 927 the much stronger punctuation of the elytra, which is plainly visible with the naked eye. DORYPHORA PICTIPENNIS, Sp. nOV. Black. Thorax with strongly rounded sides, the latter closely punctured; elytra testaceous, irregularly and closely covered with numerous small black spots. Length 8| lines. Head extremely finely punctured, the lower edge of the epistome and the anterior margin of the labrum sometimes testaceous; antennae scarcely extending beyond the base of the thorax, black, the apices of the first two joints sometimes testaceous, the third joint very long and slender, the five lower joints shining, the rest opaque, pubescent, and longer than broad. Thorax very transverse, about three times as broad as long, the sides strongly rounded, the angles acutely produced, the anterior ones toothed ; surface deeply and rather closely punctured at the sides, the middle of the disk nearly impunctate. Scutellum triangular ; the apex acute, impunctate. Elytra covered with very numerous small punctures, each of which is surrounded by a black ring; at the basal margin there are some larger greenish aeneous spots ; the extreme lateral and sutural margin is also black, as well as the elytral epipleurae ; mesosternal process stout and straight. Hab. Amazons, St. Paulo d'Olivenga. (Coll. Oberthur and my own.) This species will find its place near D. glomerala, Stal, D. pluviata, Baly, and several others somewhat similarly marked ; the absence of any transverse or longitudinal elytral bands will distinguish it. DEUTEROCAMPTA DISCICOLLIS, sp. nov. Flavous or fulvous ; the sides of the breast, the disk of the thorax, and two transverse bands of the elytra, as well as a large triangular spot at the apices of the latter, black. Length 3-3| lines. Head with a few fine punctures and a distinct longitudinal central groove ; antennae short, entirely fulvous, the terminal joints slightly thickened. Thorax more than three times as broad as long, the sides straight at the base, rcunded towards the apex; surface very finely and rather remotely punctured, the middle of the disk black, the sides fulvous. Scutellum fulvous. Elytra regularly and finely punctate-striate, the punctures distinct to the apex, fulvous ; a narrow transverse band at the base extending to either margin, a much broader band at the middle, abbreviated at either margin, and a broad triangular spot near the apex of each elytron, black ; elytral epipleurae, the underside (with the exception of the sides of the breast) and the legs fulvous. Hab. Amazons, St. Paulo d'Olivenga. (Coll. Oberthur and my own ) The elytra, if the black colour is taken for that of the ground, have the margins and two narrow transverse bands (one before, the other below, the middle) fulvous. 60* |
