Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 723 contiguous; antennae more than half the length of the body, entirely fulvous, the second and third joints short and equal, fourth slightly longer ; thorax not much more than one half broader than long, the sides narrowed at the base, rounded at the middle, the anterior angles oblique, the basilar sulcation deep and well limited laterally by a longitudinal groove, surface impunctate. Elytra strongly narrowed behind, the punctured striae very regular and fine, still less strongly marked at the apex ; the first joint of the posterior tarsi as long as the two following joints together. Nikko. A single specimen. Narrower, less convex, and of lighter colour than C. lavicollis, the thorax longer and less transverse, the striae at the elytra much more regular and composed of single punctures only. The shape of this species is very pointed posteriorly, and the sides of the thorax are concave near the base, both characters which will assist in the recognition of the present insect. CREPIDODERA JAPONICA, sp. nov. Black or piceous; thorax strongly punctured within the basilar groove ; elytra distinctly punctate-striate. Length 1 f-2 lines. Head impunctate, deeply grooved between the eyes; frontal tubercles elongate, strongly raised, fulvous or piceous; palpi dark fulvous ; antennae two thirds the length of the body, black, the apices of the basal joints stained with fulvous, third and fourth joints of equal length. Thorax subquadrate, slightly broader than long, the sides rounded before the middle, constricted near the base, the latter with a deeply impressed transverse groove, limited at the sides by a perpendicular sulcus; surface rather convex, the disk impunctate, the lateral margin accompanied by a deep row of punctures which extend also across and within the basilar groove. Elytra with distinct and regular rows of punctures, which are a little less deeply impressed near the apices, the latter being of a somewhat paler colour than the rest of the surface. Legs covered with yellowish pubescence. Nikko. The rather large size and entirely black or piceous colour will assist in distinguishing this species/ The transverse groove of the thorax extends nearly to the sides, is strongly punctured, and not so well bounded laterally by a perpendicular groove as is the case in most of the species in this genus. The frontal tubercles also are very strongly developed, and sometimes of an obscure fulvous colour. CREPIDODERA BIMACULATA, sp. nov. Fulvous; antenna?, tibia?, and tarsi black ; thorax impunctate; elytra finely subgeminate punctate-striate, fulvous, each elytron with an obscure fuscous spot near the apex. Length 2 lines. Head finely transversely strigose at the vertex, impunctate, the frontal tubercles strongly raised, elongate, and bounded behind by a |
