Show 1879.2 PHYTOPHAGOUS COLEOPTERA. 779 base and apex ; surface rather more deeply punctured than the head. Scutellum elongate, pubescent. Elytra much wider than the thorax, parallel, convex, the space below the base very slightly transversely depressed; humeral callus prominent, smooth ; surface very deeply punctate-striate, the interstices costate and partly, especially towards the sides, transversely wrinkled, here and there covered with more minute punctures, and covered with long whitiim stiff hairs. Base of the femora and tibiae fulvous, apex of latter and the tarsi piceous. This species, which was sent over by Mr. Champion in numerous specimens, may be readily known from others by its metallic bronze colour and the deep punctured striae on the elytra. Genus COLASPOIDES, Castlenau. 11. C O L A S P O I D E S BATESI, sp. nov. Broadly ovate, convex ; shining metallic green, base of antennae and palpi fulvous; head and thorax obsoletely punctured, elytra distinctly punctate-striate. Length 2|-3 lines. Hab. Costa Rica. Head impunctate on the vertex, with a distinct fovea in the middle, clypeus bounded on either side by a deep depression, punctured and obsoletely transversely wrinkled; labrum aeneous ; antennae longer than half the length of the body, the four basal joints fulvous, the rest black ; apical joint of palpi piceous. Thorax transverse, nearly three times as broad as long, narrowly margined, surface convex, obsoletely punctured. Scutellum large, oblong, impunctate. Elytra slightly wider at the base than the thorax, convex, and obsoletely obliquely depressed below the humeral callus ; surface covered with numerous irregular rows of distinct but not deep punctures; interspaces smooth, impunctate. Underside, legs, and tarsi metallic green, the latter rather darker. To be distinguished from C. smaragdula, Lefev., and other allied species by its uniform coloration of the legs and tarsi and the obsolete punctuation of the thorax, as well as by the colour of the labrum. 12. COLASPOIDES PERUANA, sp. nov. Oblong, convex. Dark violaceous blue, shining; palpi, base of antennas, and the legs fulvous ; thorax distantly, elytra closely punctate-striate. Length 4 lines. Hab. Chanchomayo, Peru. Head deeply but distantly punctate, front impressed in tbe middle with a longitudinal groove ; labrum fulvous ; mandibular black : antennae rather more than half the length of the body, filiform ; the third and fifth joints of equal length ; second joint small, ovate ; the four basal joints fulvous, the rest black. Thorax more than three times as broad as long, very convex, the sides and the posterior mar- |
