Show 228 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, Hab. Cameroons. Allied to C. raffrayi Lefev. but differing in the spotted head and thorax and the black not fulvous underside. I have received a single specimen from Herr Bang-Haas. PSEUDOSYAGRUS AFRICANUS, Sp. 11. Piceous, the sides of the thorax and the legs fulvous ; thorax closely punctured ; elytra fulvous, finely punctate-striate, the punctures obsolete posteriorly, each with an oblique band at the shoulders and another below the middle, black; the anterior femora dilated into a strong tooth, the posterior ones with a smaller one. Length 5g millim. Head finely rugose, obscure fulvous, the middle piceous ; the eyes extremely large, closely approached ; clypeus not separated from the face, strongly rugose ; antennae piceous, the lower four joints fulvous, the third joint one half longer than the second, terminal joints distinctly thickened ; thorax transverse, of equal width, the sides strongly rounded, with a narrow margin, the posterior angles dentiform, the disc closely impressed with strong, round punctures, piceous with a slight metallic gloss, the sides, in shape of a posteriorly narrowed band, fulvous ; scutellum triangular; elytra regularly punctate-striate, the punctures entirely obsolete at the apex, the interstices flat and impunctate; a short black oblique band extends from the shoulders towards the suture and another of similar shape is placed below the middle, there is also an indication of a black short stripe near the lateral margins; legs fulvous, the four posterior tibiae carinate, emarginate at the apex, claws bifid; anterior margin of the thoracic episternum convex ; anterior femora with a very strong triangular tooth. Hab. Matabeleland, near Tati. This genus was established by Fairmaire on a species from Madagascar. There seems to be scarcely any difference between the present genus and Tricliona Lefev., which was published at the same time and in the same French "Annals "; but which of the genera appeared first in print I am unable to say. Tricliona was up to the present only known from India and Sumatra, but both genera agree in most details, especially in the enormously dilated anterior femora. I think, however, that the shape of the thorax is different in Pseudosyagrus, the latter being not at all narrowed in front and having strongly rouuded sides. There is a single specimen of the present insect contained in m y collection, well distinguished by its coloration. ODONTIONOPA CJERULEA, sp. n. Metallic dark blue, antennae and tarsi black, thorax extremely finely punctured; elytra convex and cylindrical, rather strongly punctured in closely arranged longitudinal rows, the interstices with a few minute punctures, the posterior femora with a distinct tooth. |
