Show 1888.] PHYTOPHAGOUS COLEOPTERA. 343 species of the genus, A. gaschkevitchi, by the colour of the thorax that of the elytra. COLASPOIDES CHINENSIS, n. Sp. Piceous ; above metallic green ; antennae, labrum, and legs flavous ; head finely rugose ; thorax remotely punctured ; elytra deeply punctate, the interstices at the sides rugose and wrinkled. Length 2k lines. Head with a longitudinal groove on the vertex, closely punctured and slightly rugose at the vertex ; clypeus finely punctured, its anterior margin nearly straight; labrum fulvous. Antennae two thirds the length of the body, very slender, pale fulvous, the terminal joint fuscous at its apex ; thorax nearly three times broader than long, narrowed in front, the sides evenly but not strongly rounded, the surface impressed with some fine punctures which disappear entirely at the sides and near the base ; scutellum impunctate. Elytra with a scarcely visible depression below the shoulders, the latter prominent, smooth; the disk impressed with rather deep and closely arranged punctures, which form very irregular rows, the interstices at the sides and at the apex rather strongly transversely wrinkled and rugose ; legs entirely fulvous or flavous. Underside nearly black. Many specimens, allied to C. martini, Lefev., and differing in the colour of the underside, the differently coloured thorax, and the want of the tooth at the femora ; C. femoralis, Lefev., has a strongly punctured thorax and differently coloured antennae and tibiae. COLASPOIDES OPACA, n. Sp. Piceous ; the labrum and the five lower joints of the antennae fulvous ; head and thorax metallic green or cupreous ; elytra blackish, opaque, the suture and lateral margin narrowly metallic. Length 2\ lines. Head with a longitudinal groove at the middle, finely and rather closely punctured, metallic cupreous or green, the clypeus not separated from the face; labrum fulvous ; palpi testaceous. Antenna? two thirds the length of the body, black, the basal five joints testaceous. Thorax transverse, the sides rounded, narrowed in front, the anterior angles thickened and acute, the posterior margin oblique at the sides and slightly sinuate, the surface very finely and closely punctured, and covered throughout with fine longitudinal strigee ; scutellum obscure cupreous. Elytra finely and closely semiregularly punctate-striate, the shoulders acute, the base without any depressions, nearly black with a very slight metallic tint, the margins very narrowly metallic green and cupreous. Underside and legs black, the breast tinged with metallic green. C. opaca may be at once known from any other species of Colas-poides by the finely strigose surface of the thorax and the nearly black and opaque colour of the elytra. COLASPOIDES SPINIPES, n. Sp. Black ; the basal joints of the antennae, the labrum, and the femora 24* |
