Show 1 9 0 5 .J OF PHYTOPHAGOUS COLEOPTERA. 4 0 3 nate, the surface impunctate, more or less black, the anterior angles broadly testaceous; scutellum black; elytra testaceous, finely and closely punctured ; under side and legs black ; the metatarsus as long as the following two joints together, claw-joint strongly inflated. Hab. Peru. Very closely allied in coloration to A . tarsata; but the head pale, the antenna? slender, without widened and pubescent joints, and the metatarsus much shorter. Of this species I possess three specimens. The species is also closely allied to A. albifrons, but is much larger, and the anterior angles of the thorax are mucronate, the under side and legs are black. From both species the broad and blunt carina will distinguish the present one; it is more pronounced than in any other species I am acquainted with. A sp il e r a a m a b il is , sp. n. Black ; thorax short, transverse, impunctate ; elytra testaceous, extremely finely and closely punctured, the apical margins black. Far. Elytra unicolorous testaceous. Length 5 millim. Of posteriorly slightly widened shape ; the head black, shining, impunctate, the vertex sometimes marked with a testaceous spot, deeply transversely grooved between the eyes, tlie latter large; palpi testaceous ; antennae black, the third and fourth joints equal; thorax short and transverse, the lateral margins rounded, the sides broadly flattened, this portion well separated from the disc, the latter impunctate, black, shining, the anterior angles produced outwards into a small tooth ; scutellum broad, black ; elytra slightly wider at the base than the thorax, convex, gradually widened posteriorly and without basal depression, testaceous, extremely closely and finely punctured, the extreme apical margins black ; under side and legs black, the metatarsus of the posterior legs as long as the following two joints together, claw-joint rather strongly swollen. Hab. Peru. The black head and thorax and the proportionately short shape of the latter well distinguish this species, of which I possess three specimens, two of which have the apex of the elytra black to a small extent and the vertex marked by a small testaceous spot; in the other specimen the spot and the black apex of the elytra are absent. Elytra with metallic transverse bands. A s p h ^bra c a r il lo e n s is , sp. n. Testaceous ; the head, breast, and the legs black ; antennae long, fulvous ; thorax impunctate, anterior angles bluntly produced; elytra nearly white, impunctate, a transverse band at the base and another narrower one, slightly oblique, metallic dark blue, both bands abbreviated at the sides. |
