Show 168 MR. M. JACOBY ON N E W [Mar. 2, 5. LAMPROSOMA GUATEMALENSE, sp. nov. Oblong-ovate, narrowed behind, convex. Black ; above violaceous blue ; head, sides, and anterior margin of thorax and a broad band at the extremity of the elytra cupreo-aureous. Length 1| line. Hab. Zapote, Guatemala. Head obsoletely impressed in the middle, not closely, but distinctly punctate ; labrum black. Sides of the thorax greatly deflexed, the lateral margins slightly rounded, anterior angles very acute; surface closely punctured, but not more deeply than the head ; the sides and anterior margins are occupied by a broad cupreo-aureous band, leaving only the middle of the base and a protruding point at the middle of the ground-colour. Elytra regularly convex and narrowed behind, rather deeply punctate-striate, dark violaceous blue; a broad band of the same colour as that of the thorax is placed at the last third near the lateral margin, and extends across the suture to the other side, covering at the same time the extremity of the elytra. Underside and legs black. This species is closely allied to L. scintillans, Lac, and others described by the same author, from all of which it differs, however, in the shape of the band of the thorax as well as that of the elytra and the distinct punctation of the head. Collected by Mr. Champion. Collection of Godman and Salvin. 6. LAMPROSOMA POLITUM, sp. nov. Oblong-ovate, convex, narrowed behind. Metallic green; tarsi and antennae (the second and third joints of the latter excepted) black ; head distinctly, thorax minutely, punctate ; elytra narrowed behind, with ten rows of deep punctures, the interstices minutely punctate. Length 2| lines. Hab. Brit. Honduras (Blancaneau). Head slightly convex, very distinctly punctured ; eyes broadly emarginate; labrum black. Thorax transversely convex, its sides straight; the anterior margin not produced in the middle, regularly concave at each side ; posteriorly acutely produced in the middle, the sides regularly crescent-shaped ; surface scarcely punctured. Scutellum black. Elytra regularly convex, slightly narrowed posteriorly, the lateral lobes acutely, but moderately, produced; each elytron with ten rows of very deep punctures, the last two outer rows of which are much closer approached than the others: the interstices also finely punctate. Prosternum slightly longer than broad, distinctly, but not closely, punctured. This species resembles much L. speciosum, Lac, from Brazil; but it is narrower, less convex ; the thorax is much finer punctured, and the interstices of the strice on the elytra are also minutely punctate ; and as the locality is also far removed, it is no doubt a good species. Collection of Godman and Salvin. |
