Show 780 MR. M. JACOBY O N N E W [Dec. 16, gin much rounded, the latter broadly produced in the middle, the angles acute, the anterior ones slightly produced; surface remotely but distinctly punctured. Elytra broadly oblong, rather convex posteriorly, rather closely and regularly punctate-striate, more distinctly near the base than towards the apex, where the punctures diminish greatly in size. Entirely dark violaceous blue ; underside of the same colour, the legs and tarsi fulvous. Thighs unarmed. Distinguished from C. alcyonea, Erichs., by its greater size, the colour of the antennae and the underside; from C. tibialis, Lefev., by the uniform coloration of its legs. 13. COLASPOIDES AUSTRALIS, sp. nov. Oblong-ovate, broad. Bluish aeneous beneath, cupreous or violaceous above; base of antennse, labrum, and legs fulvous ; thorax coarsely, elytra substriate-punctate. Length 3 lines. Hab. Australia, Queensland. Upper portion of the head finely, lower portion coarsely punctate ; the apex of the clypeus, labrum, and palpi fulvo-testaceous ; antennae filiform, the first six or seven joints fulvous, the rest black. Thorax twice as broad as long, sides nearly straight at the base, rounded and narrowed towards the apex, the posterior margin being in consequence double as wide as the anterior one; surface convex, not very closely impressed with deep oblong punctures, which are more crowded at the sides than on tbe disk. Scutellum very broad, smooth, metallic green or cupreous. Elytra slightly depressed below the basilar space, the depression not quite extending to the suture, rather deeply and regularly punctate-striate, the interspaces smooth, but transversely wrinkled below the base near the lateral margins; the latter are also impressed through their entire length with deep punctures ; the first two rows of punctures unite before the middle and form one row of closely approached punctures which runs parallel with the suture to the apex, the latter obsoletely costate. Underside piceous with a metallic bluish gloss, legs piceous or dark fulvous, thighs not armed with a tooth. 14. COLASPOIDES UNICOLOR, sp. nov. Ovate, very convex. Dark violaceous, base of antennae and palpi testaceous ; bead and thorax distantly, elytra closely punctured. Length 3 lines. Hab. Chontales, Nicaragua. Head deeply but not closely punctured, with a longitudinal groove in the middle of the vertex; clypeus more closely punctured, labrum metallic green ; basal joints of palpi fulvous, the apical joint piceous ; antennae filiform, the third joint very slender and the longest, th? fourth half the length, the three or four basal joints testaceous, the rest black with a greenish gloss. Thorax very narrow, at least three times as wide as long, sides evenly rounded, posterior margin much produced towards the middle, anterior one much deflected towards the sides, surface very distinctly punctured on the disk, more closely |
