Show 1900.] FROM SOUTH AND CENTRAL AFRICA. 223 white hairs ; scutellum broader than long, punctured and pubescent ; elytra with a deep fovea below the base, the interior of which is of metallic greenish or brassy colour, the rest of the surface irregularly transversely rugose and pubescent, with two or three narrow raised longitudinal ridges, the most well-marked of which is placed near the suture ; below and the legs coloured as the upper surface aud closely pubescent. Hab. Tumbu, Congo. Of this species one specimen is in the collection of the Belgian Museum and the other in my own. I know of no other Colasposoma having such a deep and well-marked elytral fovea in connection with the long pubescence; in C. foveipenne Jac, from Madagascar, there is a similar but transversely shaped fovea, but no pubescence, and a totally different sculpturing. The coloration of the present species also is peculiar, being a mixture of obscure fulvous and metallic brassy or aeneous. I am at present unable to speak with certainty as to the sex of the specimens before me, but both are probably females. C. foveatum Jac differs in having a transverse elytral cavity and a strongly and remotely punctured thorax. COLASPOSOMA OBSCURUM, sp. n. Obscure fuscous with cupreous gloss ; antennae with the second and third joints fulvous ; thorax extremely closely punctured and finely reticulate ; elytra strongly punctured in closely approached rows, the interstices nearly smooth. Length 6 millim. Of parallel shape; entirely obscure aeneous or fuscous, here and there with cupreous reflections; antennae long, black, the first joint below and the following two joints fulvous, terminal joints slightly thickened ; thorax more than twice as broad as long, slightly narrowed anteriorly, the sides feebly rounded, the entire surface extremely closely and finely punctured, with the interstices everywhere finely reticulate; scutellum with a few punctures ; elytra with a shallow depression below the base, rather strongly and closely punctured in irregular rows, the sides below the shoulders with an elongate depression; femora unarmed; legs nearly black. Hab. Salisbury, Mashonaland, on Brachystegia (67. Marshall). Mr. Marshall has sent two specimens (probably males) of this species, which I cannot identify with any of the numerous other members of the genus : the peculiar coloration, and the almost entire absence of elytral rugosities in connection with the closely and finely punctured and reticulate thorax, will assist in tbe recognition of the species.
