Show 1885.] COLEOPTERA FROM JAPAN. 195 band at the sides black ; surface impunctate, a few punctures only are placed near the sides. Scutellum black. Elytra much wider at the base than the thorax, subquadrate-oblong, the punctured striae arranged in the following way :-a double row placed close to the sutural margin, the following space broader than that occupied by the punctures and raised in a costa near the apex ; the eight following rows of punctures regularly placed, but the first and the last three of these very deeply impressed ; the interspace in front of the last two rows costate ; the black sutural band extends to the first row of punctures, the discoidal band occupies the space between the third and eighth rows, both bands are connected with a small triangular black spot at the apex. Underside and legs are entirely black. Nikko. A single specimen. CRIOCERIS ORIENTALIS, sp. nov. Below, the lower part of the head, a spot at the vertex, antennae, and legs black; thorax cylindrical, fulvous; elytra testaceous, distinctly punctate-striate. Length 2 | lines. Head impunctate, black, sparingly covered with yellow pubescence; vertex fulvous, with an elongate blackish central spot. Antennae half the length of the body, black, the second joint extremely short. Thorax cylindrical, scarcely constricted at the middle, with a narrow transverse groove close to the basal margin ; surface remotely and very finely punctured, fulvous, the sides below black. Scutellum black. Elytra convex, of paler colour than the thorax, regularly and rather strongly punctate-striate, the punctuation getting finer towards the apex; at the shoulder a small piceous spot is visible. Underside and legs black. Sapparo. Of this species only a single specimen is before me, which in structure is without doubt closely allied to C. 1'2-punctata and several others, in which the thorax is nearly cylindrical. The absence of any spots at the disk of the elytra and the general colour of the present species will help to distinguish it. Genus PEDRILLIA, Westw. P E D R I L L I A A N N U L A T A , Baly. In all the specimens which were obtained at Nikko the black spot of the head and thorax as described by Mr. Baly is wanting, but in every other respect the insects agree. PEDRILLIA NIGRICOLLIS, n. sp. Black, pubescent; elytra testaceous, closely punctured. Length 2 lines. Head strongly punctured in front of the eyes, the intermediate space and the vertex smooth and shining; eyes deeply notched ; the space in front of the clypeus deeply foveolate. Antennae half the 13* |
