Show 244 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, black, the lower five or six joints fulvous, third and fourth joint equal, slightly longer than the second, terminal four joints strongly thickened, about one-half longer than broad ; thorax twice as broad as long, the sides moderately rounded, the anterior angles obliquely thickened, the surface minutely granulate, closely and rather strongly punctured; scutellum broader than long; elytra slightly widened towards the middle, the punctures slightly larger in size than those of the thorax, and arranged in somewhat irregular rows, intermixed with other minute punctures, the punctation more distinct anteriorly ; underside shining, greenish aeneous, the tibiae and tarsi fulvous ; the metatarsus of the posterior legs as long or slightly longer than the following joints together. Hab. Dunbrody, Cape Colony (Eev.J. O'Neil). From other African representatives of this genus the present species may be known by the arrangement of the punctures in distinct, although irregular and well-separated rows ; the structure of the head, which is rather convex and without the slightest separation between the clypeus, will further assist in the recognition of the species, of which 1 received two specimens. PHYLLOTRETA UNICOSTATA, sp. n. Flavous, the breast aud abdomen black ; thorax minutely granulate, very finely and closely punctured; elytra greenish aeneous, strongly and closely punctured in rows, the sides with a longitudinal costa. Length 2 millim. Head impunctate, the frontal elevations obsolete, clypeus broadly triangular ; antennae extending to the middle of the elytra, flavous. the terminal four joints fuscous, short, and slightly widened, second and third joint equal, the following four much more elongate; thorax one-half broader than long, distinctly narrowed anteriorly, the sides straight, anterior angles thickened, posterior margin slightly sinuate at each side, the disc very finely and closely punctured, the interstices very minutely granulate, opaque, pale flavous; scutellum broader than long, black; elytra much more strongly punctured than the thorax, the punctures arranged in closely approached, slightly geminate rows, with a single distinctly raised and acute costa extending from the shoulders nearly to the apex ; below black ; the legs flavous, the posterior femora strongly incrassate ; prosternum very distinct. Hab. Pt. Alfred, South Africa (Rev. J. O'Neil). There will be no difficulty in recognizing the present species, on account of its coloration and the sculpturing of the elytra • the general shape of tbe species and that of the thorax is typical of the genus, and the terminal short joints of the antennae are peculiar to the species, of which I have received several examples. LONGITARSUS SALISBURIENSJ.S, Sp. n. Elongate-ovate, winged, the head and thorax obscure fulvous, opaque, closely punctured : elytra flavous, punctured like the thorax |
