Oblongus, ater, vix nitidus; capite lato, planato, crebre fortiter longitudinaliter ruguloso-punctato: thorace quam caput £ latiore, latitudine quam longitudo £ majore, sat convexo, confertim fortiter punctato, antice posticeque oblique angustato, lateribus medio subparallelis, angulis anticis subacutis prominulis, posticis acutiusculis vix divaricatis; elytris basi thorace haud lalioribus, postice paulo ampliatis, convexis, fortiter sulcatis, sulcis seriebus punctorum magnorum transversim impressis, interstitiis angustis cariniformibus, nitidis; humeris denticulo acuto armatis; pedibus brevibus obscure piceis, tibiis asperatis. Long. 3 lin., lat. lg lin. This species is closely allied to A. obscurus, G. Waterh., but is relatively broader. The 4th to the 11th joints of the antennae are very strongly transverse ; the forehead is more strongly punctured ; and the interspaces are inclined to form rugulae, especially near the eyes. The thorax is more strongly punctured, about \ broader than long (whereas in A. obscurus it is only as broad as long) ; the sides are more sinuous. The costae of the elytra are more pronounced, and the channels are more slightly punctured. The legs are shorter somewhat and rough. Hab. Charles Island. Brit. Mus. PHYTOPHAGA. HALTicrr3.E. DOCEMA, gv.n. nov. Antennae approximate at their base. Claws simple. Cotyloid cavities for the anterior coxae open. Prothorax marked posteriorly with a transverse impressed line, not bounded on each side by the short longitudinal impression. Posterior femora not reaching to the extremity of the elytra. Basal joint of the posterior tarsi as lon°* as the two following joints taken together; the 2nd and 3rd joints about as long as broad. The position of this genus appears to m e to be next to Graptodera. |
