1. Genus: Colobopterus Mulsant, 1842' Key to groups 1 (2) Elytra very short, scarcely longer than prothorax (Fig. 20). Body strongly convex, surface bare. Elytra black with yellow marking. Front with three tubercles, genae shmall. Basis of pronotum bordered, posterior angles truncate or weakly emarginate. 3.5-4.5 mm. (The species of group Megatelus Reitter does not occur in South Africa) Group 1: Megateloides 2 (1) Elytra distinctly longer than prothorax. 3 (6) Scutellum impressed. 4 (5) Clypeus deeply emarginate, both sides with long, in females with short lobes. 8-9 mm Group 2: Neocolobopterus 5 (4) Clypeus at most weakly emarginate, both sides simply rounded. Elytra mostly flattened. Front with a tubercle or (in females) with a more or less distinct knob. Elytra with punctate rows, or with finely carinated striae. 5-16 mm Group 3: Colobopterus 6 (3) Scutellum not impressed. Elytra convex. Front of males with three tubercles or almost simply convex. Punctate rows of elytra never edged on sides. 4.5-10 mm Group 4: Teuchestes Group 1: Megateloides - - Only one species. Elytra black, a small humeral spot and broad apex yellow. Hind metatarsi much longer than upper thorn of hind tibiae and shorter than next three joints together. 3.5-4.5 mm. RSA (Transvaal), (= diadimitus Petrovitz, 1951) dimidiatus Roth, 1851 Group 2: Neocolobopterus - - Only one species. Genae distinctly separated from clypeus. Elytra black, Intervals weakly convex. Hind metatarsi longer than upper thorn of hind tibiae and as long as next three joints together. 8-9 mm. RSA, (= ballioni Schmidt, 1906, senegalensis Reiche, 1852, non Klug, 1835, thoracicus Roth, 1851 part.) abessinicus Harold, 18^1 Group 3: Colobopterus 1 (2) Striae of elytra finely, but distinctly edged on both sides, intervals reticulated, oily. Genae small, rounded. Basis of pronotum in middle mostly without border. 5-8 mm. - RSA (Cape Province, Natal, Transvaal), SWA, Angola, Zimbabwe-Rhodesia maculicollls Reiche, 1847 Aberrative forms: 1. Pronotum dark, sides broadly yellow, elytra yellow to brownish yellow forma typica ?. Pronotum as in forma typica, elytra entirely or near entirely dark or black ab. nigricans Paulian, 1934 3. Sides of elytra very narrowly yellow, elytra dark or black ab. marginlcollJB Harold, 1859 2 (1) Striae of elytra simply punctate, intervals not or indistinctly reticulated, more shiny. Middle of pronotal basis without border. 3 (4) Striae of elytra very fine, intervals flat, broad, nearly smooth. Elytra weakly contracted to apex. Reddish yellow, disc of pronotum and scutellum black. Hind metatarsi somewhat shorter than upper thorn of hind tibiae and longer than next two joints together. 9-11 mm. RSA (Cape Province) senegalensis Klug, 1835 4 (3) Striae of elytra strongly furrowed, intervals convex, distinctly punctate. Elytra rather strongly contracted to apex. Reddish yellow, head, disc of pronotum, scutellum and suture of elytra dark. Hind metatarsi as long as upper thorn and as next three joints together. 8-16 mm. - RSA (Cape Province) principalis Harold. 1865 I regard the "subgenera" only as groups of species, because the characters of many "subgenera" are considerably heterogenous. The short diagnoses of genera and groups of species will be given only in the keys to genera and groups.
