Show 264 MR. F. p. PASCOE O N T H E COLEOPTERA O F PENANG. [May 8, Head rather transverse in front; antennary tubers short, distant. Eyes moderate, deeply divided. Antennae shorter than the body, sublinear, the scape subcylindrical, as long or a little longer than the third joint, the fourth and fifth equal and shorter, the last six very short, all nearly cylindrical, except the last, which is ovate and pointed. Prothorax quadrate, regular, not broader than the head. Elytra cuneate, much broader than the prothorax at the base, the sides abruptly declivous, the angle scarcely forming a carina, the apex subtruncate. Legs moderate, slender; the intermediate tibiee entire ; tarsi with the basal joint short; claws obtusely toothed at the base. Anterior acetabula slightly angulated. Pro- and meso-sterna rounded. The peculiar shortening of the terminal joints of the antennae (as in many Apomecyninar) will readily distinguish this genus, which in style of coloration bears a striking resemblance to the last (Tany-lecta). The two specimens before me appear to be females; almost as a matter of course, therefore, the toothed claws will characterize both sexes, not the male sex only, as it appears to do generally in Glenea. ZOSNE CINCTICORNIS. (PL XXVIII. fig. 1 I.) Z. nigra, subnitida, lineis maculisque cdbo pubescentibus ornata; antennis albis, medio et apice nigris. Black, nearly glabrous, subnitid, with lines and spots of short white hairs; head with two central white lines on the vertex, another behind the eye, the front and cheeks white; lines on the head continued on the prothorax, the central, however, contiguous, the intervals sparsely pubescent and rather finely punctured; scutellum white, densely pubescent; elytra coarsely punctured, with numerous irregular white spots ; body beneath with a white silvery pile, the sterna striped with black, two blackish spots on the side of each abdominal segment; legs and antennae with a close greyish-white pubescence, the latter a little longer than half the length of the body, and having the upper half of the fourth and the whole of the fifth and eleventh joints black. Length 8 lines. OBEREA. Oberea, Mulsant, Hist. Nat. des Coleopt. de Fr., Longicornes, p. 194 (1839). Isosceles, Newman, The Entom. p. 318 (1840). OBEREA CURIALIS. O. nigra; capite, prothorace, pedibus anticis et femoribus inter-mediis rubris; abdomine segmentis duobus basalibus argenteis. Black ; head, prothorax, anterior legs, and intermediate femora deep orange-red; metasternum and abdomen black, the latter with its two basal segments silvery white; head and prothorax finely punctured, the prothorax transverse, neither wider nor longer than the head; scutellum narrow, truncate, red, silvery in certain lights |
