Show 444 MR. M. JACOBY ON N E W [Mar. 15, gitudinal short band and the clypeus metallic green. Antennse like those of the preceding species. Thorax narrowly transverse, sides nearly straight at the base, thence to the apex slightly rounded ; surface very closely punctate near the sides, more remotely at the disk, metallic green, this colour divided by four longitudinal bands, of which the two middle ones are the broadest, but do not qnite touch the apex, the bands placed at nearly equal distance from each other, another shorter purplish spot is placed on each side at the extreme lateral margin. Scutellum depressed at its base, deeply punctured. Elytra of exactly the same shape and sculpture as in C. gibbicolle, metallic green, each elytron with a subsutural broad dark purplish band, and another lateral one, both uniting at their apex. Underside and legs seneous, finely pubescent, anterior femora with a very short tooth. A variety does not differ except in its uniform colour of green or brownish seneous but in certain lights traces of the darker bands are also here visible. 12. COLASPOSOMA ANTENNALE, sp. nov. Broadly ovate, convex. Metallic green or seneous; antennse and legs fulvous, the former long, filiform ; thorax and elytra deeply punctured, interstices of latter transversely rugose throughout. Length 3-3f lines. Hab. South Africa. Head longitudinally strigose at the vertex, closely punctured at the middle ; clypeus divided from the front by a distinct transverse angulate groove, closely punctured near the lower margin. Labrum narrow, fulvous. Antennse as long as half the body in the male, slender, all the joints elongate, the terminal ones not thickened, fulvous, apex of apical joints piceous. Thorax transverse, convex, rather broad, sides much rounded, angles acute, the anterior ones thickened and produced into a point; surface closely and deeply punctate at the sides, less so at the disk, the middle of which is partly smooth and impunctate. Scutellum rugose punctate, not broader than long. Elytra oblong, convex, slightly narrowed towards the apex, surface very closely and deeply punctate and transversely rugose. Abdomen finely rugose, very finely pubescent. Specimens which I refer to the female insect have the antennse a little shorter and the thorax less transverse. In m y collection. To be distinguished from C. senegalense, Cast., by its denser punctuation of the thorax and elytra, more elongate shape, and the different antennse ; from C. chloris, Lefev., by the close transverse rugosities which cover nearly the entire elytra, while G. femorale, Lefev., has differently coloured legs and antennse. 13. COLASPOSOMA ORNATICOLLE, sp. nov. Oblong, convex. Black; legs, breast, and head purplish blue; thorax aureous, densely punctured; elytra purplish, the suture metallic green. |
