Show 776 MR. M. JACOBY ON N E W [Dec 16, thorax finely. Elytra strongly punctured, each elytron with three small tubercles placed triangularly. Length 1^ line. Hab. Capetillo, Dueiias, Guatemala. Head flat, distinctly punctured, fulvous, eyes deeply emarginate. Antennae as long as the thorax ; the joints from the fifth to the apex transverse, broader than long ; the four basal joints fulvous, the rest black. Thorax regularly narrowed from base to apex, its sides straight, surface regularly convex, finely punctate and pubescent, violaceous blue. Scutellum large, darker blue, opaque. Elytra narrowed posteriorly, their apex broadly rounded, closely covered with deep oblong punctures, their sutural margins denticulate through their entire length, each elytron with a short transverse tubercle placed in the middle near the sutural margin, while another small round tubercle is situated above and one below it, the three forming together a triangle. Pygidium fulvous, with a central blue patch. Underside violaceous blue, broadly bordered with fulvous. Legs fulvous, the middle and posterior tibia?, as well as the posterior femora, with a blue spot. This species ought to follow C. cinerea, Lac, to which it bears a close resemblance; it may, however, be distinguished by the coarser punctuation of the elytra and the three tubercles on the latter. Genus LAMPROSOMA, Kirby. 6. L A M P R O S O M A N I C A R A G U E N S E , sp. nov. Broadly ovate,very convex. Above dark violaceous ; body beneath, the head, sides of the thorax, and a short lateral stripe near the apex of the elytra cupreo-aureous. Length 3\ lines. Hab. Chontales, Nicaragua. Head finely granulose, distinctly but not closely punctured; middle impressed with a small round fovea; anterior margin of clypeus concave; labrum and apex of mandibulse black ; first joint of the antennae cupreous, second joint fulvous, the rest more or less metallic greenish black. Thorax twice as broad as long, sides rounded, moderately converging from base to apex ; posterior margin rather deeply sinuate on either side, and obsoletely depressed on each side of the middle lobe ; surface transversely convex, impunctate at the sides, distinctly but not closely punctured on the disk, more deeply towards the base, violaceous blue with a distinct tint of greenish olive, and a broad band of bright reddish copper-colour parallel with the lateral margins. Elytra very convex at the base, thence to the apex greatly deflexed, slightly longer than broad, each elytron covered with ten rows of very deep punctures, the interstices smooth and impunctate, of the same colour as the thorax, with a short lateral band of bright aureous near the apex. Entire underside and legs metallic aureous. From L. preticsum, Lac, distinguished by the punctures of the thorax and the colour of the antennae and the elytra. From L. dives, |
