Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 745 GALERUCELLA SEMIFULVA, sp. nov. (Plate XLVI. fig. 11.) Ovate-oblong, convex; head, antennae, breast, and legs black ; thorax fulvous, the disk black ; elytra closely punctured and finely pubescent, rufous or fulvous ; abdomen testaceous. Length 2\ lines. Head closely rugose-punctate, black, the lower part of the face testaceous ; the frontal tubercles but slightly raised, but separated by a narrow groove. Antennae rather more than half the length of the body, black, the underside of the lower joints more or less testaceous, the third joint distinctly longer than the second or the fourth. Thorax narrowly transverse, three times as broad as long, the sides distinctly rounded at the middle, the angles tuberculiform, the anterior ones furnished with a single seta ; the surface rather deeply depressed at the sides, closely rugose-punctate, the middle of the disk with a more or less broad longitudinal black band. Scutellum broad, black, rugose-punctate, and covered with yellow pubescence. Elytra convex, more finely punctured than the thorax, rufous or fulvous, covered with fine yellow hairs. The first joint of the posterior tarsi a little longer than the second; claws bifid. Kiga. GALERUCELLA VITTATICOLLIS, Baly. The description of Mr. Baly of this species, the type of which I have before me, requires some additional remarks:-The antennae have the first three or four joints testaceous below (not piceous as the description says) ; the thorax is rugose, punctate at the sides only, where they are deeply depressed; the middle portion of the disk consists of a longitudinal raised, smooth and shining space, which is sometimes of a darker tint than the rest of the surface (in no specimen do I find a black broad band as given by the author). The elytra show occasionally an obscure fuscous lateral narrow band from the shoulder to below the middle, which is, however, generally absent; their punctuation is often more coarse than that of the thorax, but varies in depth. Yokohama. GALERUCELLA MODESTA, sp. nov. Ovate, convex ; pale fulvous ; base of the head, antenna?, tibia?, and tarsi black; above darker fulvous, finely pubescent, closely punctured ; thorax with a central blackish band; breast piceous. Length 1| line. Head rugose-punctate, black, pubescent, lower part of face fulvous; labrum and palpi piceous. Antennae black, the three basal joints testaceous below, the third and fourth joints equal. Thorax transverse, the sides strongly rounded and produced at the middle, the angles acute but scarcely produced; surface with a longitudinal central groove and a deeper depression at each side, closely rugose-punctate, fulvous, the central depression piceous. Scutellum black, punctured and pubescent. Elytra rather convex, and nearly parallel, punctured like the thorax, and thinly covered with yellow hairs. |
