1900.] FROM SOUTH AND CENTRAL AFRICA. 223 



white hairs ; scutellum broader than long, punctured and pubes- 

 cent ; 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 and closely pubescent. 



Bab. 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 G. 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. 0. 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 obscui"e 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. 



Bab. Salisbury, Mashonaland, on Brachystegia (G. 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 the 

 recognition of the species.
