The smooth lateral carina (extending from the posterior angle to near the front angle) straighter than in most of the allied species. Prosternal process chanelled and coarsely punctured. Abdomen densely and finely punctured, except at the posterior margins of the segments. The last segment with a narrow, elongate, triangular notch at the apex. The upper and apical parts of the femora, the posterior edge of the tibiae, and the tarsi coppery. PlEZONOTUS DISCOIDALIS, Sp. n. Niger, depressus, viridi-squamosus; thoracis disco elytrorumque sutura calvis. Long. 11, lat. 6 millim. Apex of the rostrum about one quarter broader than the length of the rostrum itself, narrowed at the base, flat above, with a trace of a short ridge in the middle at the apex; forehead with an impressed line between the eyes. Thorax as long as broad, gently convex, a little more narrowed in front than at the base, moderately rounded at the sides. The disk with closely placed, round, shining granules, each granule marked with a puncture. The sides clothed with light green scales. Elytra one-fifth longer than broad, rather flat, gradually declivous at the apex; at the base not broader than the base of the thorax ; evenly rounded at the sides, with no distinct shoulders; punctate-striate ; the interstices with numerous (but not very closely placed) round shining granules; all the interspaces (except on "the smooth suture) clothed with light green scales, with a few coppery scales interspersed. Underside (except the apex of the abdomen) and the legs clothed with pale green scales, intermixed with pale pubescence, which on the legs is rather long. The discovery of a fourth species of this genus of Curculionida is of some interest, the three species previously known having been described from Java, Amboyna, and Punipet. |
