244 ME. M. JACOBY OU 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. 



Hah. Dunbrody, Cape Colony (Rev. 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 and 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 postei'ior 

 femora strongly incrassate ; presternum very distinct. 



Hah. Pt. Alfred, South Africa (Rev. J. O'NeiT). 



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 the 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. 



LoiNGITARSUS SALISBURIENS1S, Sp. U. 



Elongate -ovate, winged, the head and thorax obscure fulvous, 

 opaque, closely punctured : elytra flavous, punctured like the thorax
