Show 1893.] FROM BRITISH CENTRAL AFRICA. 743 sericeo, metastemi abdon™"-(sque medio subglabro. Long. 28, lat. 9 mm.; long, *vutelli 3 mm. Violet-coloured. *™b. the legs and antennae black. Pronotum and elytra f-'^red with i dark velvety pile, scarcely dense enough t;0 ,j~Lure the dark-blue and violet' colour of the derm except near the base of the elytra and on the middle of the pronotum, with a narrow glabrous and sparsely punctured band extending for some distance along the middle of each elytron between the horizontal sutural region and the more oblique'lateral portion. The disk of the prothorax may be observed in places, where the pile is rubbed away, to be transversely wrinkled. The scutellum is rather elongated, much attenuated behind, and transversely rugose above. The prosternal process is very feebly and obtusely tubercled behind. The fifth and sixth ventral segments of the abdomen in the male are somewhat arcuately emarginate behind. The intermediate femora each bear a blunt tooth or rather tubercle on the underside near the apex ; on the anterior femora the apical tooth is still more obsolete. The male antennas are a little longer than the body. 39. PHILEMATIUM NITIDIPENNE, Gahan. Philematium nitidipenne, Gahan, Trans. Ent. Soc. Lond. 1890, p. 307.

Long. 15-17 mm. 3 2 • From A. clavicornis, Fabr., and allied forms the present species is chiefly to be distinguished by its less incrassated antennas and by the punctuation of the head and prothorax. The front of the head bears a tolerably distinct transverse line across the middle, which divides it into an upper more thickly punctured portion, and a lower more sparsely punctured epistomal region; the vertex also between the eyes is very sparingly punctured. The punctures of the prothorax are close and somewhat confluent on the lateral portions of the disk; but those along the middle of the disk and on the sides of the prothorax are less closely placed and have distinct intervals between them. In clavicornis, Fabr., and scalaris, Pasc, the head and prothorax are more closely and somewhat more strongly punctured. The lower or epistomal portion of the front of the head is almost or quite as thickly punctured as the upper portion, and there is as a rule no distinct impressed line separating the two. The prothorax is very closely and pretty uniformly punctured. PROC. ZOOL. Soc-1893, No. L. 50 |
