Show 1878.] MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. 989 13. CHALCOPHANA UNIFORMIS, sp. nov. Entirely dark rufous, with the exception of the last five joints of the antenna?, the apex of the tibia?, and the tarsi. Thorax finely, elytra deeply geminate-punctate-striate, and more or less costate. Length 3-3 J lines. Head exactly punctured as in semirufa, the antenna? also coloured as in that species. Thorax a little more finely punctate. Elytra distinctly and closely punctured, the punctures running together in pairs, the interstices either raised over the whole disk in costa?, or only distinctly visible towards the apex. The underside rufous; extreme apex of tibia? and the tarsi black. Hab. Costa Rica. This species may possibly be only a variety of C. semirufa ; but the uniform coloration, the punctuation of the elytra approached in pairs distinguish it sufficiently from that, species, while the colour of the first six joints of the antenna? will separate it from species in other respects similarly coloured. 14. DORYPHORA BRUNNEIPENNIS, sp. nov. Broadly ovate, narrowed behind, below black ; antennae with the last two joints yellowish white. Head, thorax, and elytra rufous, opaque. Length 6 lines. Head strongly but not closely punctate, brown with a greenish tint ; antenna? brownish seneous, last two joints whitish. Thorax with the sides parallel, the anterior angles acute; surface with the same-sized punctures as the head, but closely and uniformly distributed. Scutellum smooth, broadly triangular. Elytra broader at the base than the thorax, very convex at their first third, from there strongly declining to the apex, the latter pointed ; surface finely and irregularly punctured and longitudinally aciculate, the intervals finely alutaceous, opaque, of a uniformly rufous colour. Beneath black ; mesosternal process robust, long, slightly curved. Legs rufous. Hab. Columbia. Collection Jacoby. 15. DORYPHORA FLAVIPENNIS, sp. nov. Greenish black, shining. Head and thorax strongly punctate. Elytra sparingly irregularly punctured, flavous, a sutural stripe narrowed towards the apex, greenish black. Length 5^ lines. Head more strongly punctured near the apex than at the vertex; antenna? with the last five joints flattened and widened, the first five joints testaceous, stained with greenish seneous above, the rest fuscous. Thorax more strongly punctured than the head, very coarselv towards the sides, dispersedly on the disk. Scutellum smooth. Elytra rotundate towards the apex, parallel near the base, sparingly and rather finely punctate without order, the intervals finely aciculate ; the extreme outer margin has a row of punctures, and is accompanied, at some distance, with another row of double |
