Elytral striae and primary intervals broad, secondary ones very narrow. 4 mm. - RSA (Cape Province) sparsepunctatus Petrovitz, 1964 28 (27) Hind angles of pronotum rounded, basis not or indistinctly emarginate. 29 (30) Smaller. Hind metatarsi about as long as upper thorn of hind tibiae. Elytra very finely reticulate, rather shiny. 4-5 mm. - RSA (Cape Province) oreotragi Endrődi, 1978 30 (29) Bigger.

Genae strongly produced beyond eyes. Hind metatarsi as long as upper thorn of hind tibiae and somewhat shorter than next three joints together. 4 mm. - Botswana (hastulifer Petrovitz, 1958) 4 (3) Scutellum normal, on basis parallel or triangular. 5 (6) Head densely pilose. Clypeus deeply emarginate, both sides of emargination very sharp and projecting laterally. Pronotum very densely punctate. 3 mm. - RSA (Cape Province) hirticeps Péringuey, 1901 6 (5) Head glabrous. Pronotum not very densely punctate. 7 (8) Pronotum with rather sparse and big punctures, mixed with micropunctures. Clypeus with two sharp denticles or obtuse angles. Genae lightly produced. Hind metatarsi about as long as upper thorn and almost as next three joints together. 3.5-5 mm. RSA (Transvaal, Cape Province), SWA-Namibia I

gnotus Schmidt, 1922 Aberrative forms: 1. Clypeus with two obtuse angles ab. merula Balthasar, 1941 2. Elytra without humeral denticle ab. corax Balthasar, 1937 3. Elytra shorter, sides curved ab. subovalis Endrődi, 1960 4. Elytra reticulated, oily ab. rugulosus Endrődi, 1964 8 (7) Pronotum with very small and with only somewhat bigger punctures. Sides of clypeus straight, genae strongly produced. Elytra twice longer than both together. Hind metatarsi somewhat shorter than upper thorn and as long as next two joints together. 3.54.5 mm. - RSA (Transvaal). Bechuanaland hetaerus Petrovitz, 1958

x 9 (2) Front with a distinct tubercle. Clypeus with two sharp denticles, genae produced. P-t-onotum in male almost without punctures, in female rather densely punctate. Hind metatarsi shorter than upper thorn and shorter than next three joints together. 5-6 mm. - RSA discolor Erichson, 1859 10 (1) Apex of clypeus rounded beside emargination. 11 (26) Front with a sharp middle tubercle and mostly with two smaller lateral tubercles. 12 (13) Lateral tubercles of head connected by a carina with the apical margin of clypeus (Fig. 36). Reddish brown. Pronotum with a small impression behind apical margin, baBis without border. Posterior legs about as in preceding species, 5-6 mm. - RSA (Transvaal, Oranje), (= ferrugineus Boheman, 1857, bohemani Harold, 1862) guineensis Klug, 1855 13 (12) Lateral tubercles not connected with the apical margin of clypeus (Fig. 37). 14 (15) Posterior tibiae thickened in the middle (Fig. 38). Yellowish brown. Genae produced, front with three tubercles. Pronotum very sparsely punctate, basis without border. Hind metatarsi shorter than upper thorn of hind tibiae and as long as next two joints together. 6 mm. - RSA curvodilatatus Schmidt. 1909 15 (14) Posterior tibiae normal, successively thickened to apex (Fig. 39). 16 (25) Hind metatarsi as long as or scarcely longer than next two joints together and always shorter than next three joints. A

. vividus Petrovitz, 19G4 is (after diagnosis) very similar to A . hetaerus Petrovitz, but sides of clypeus convexly curved, elytra 1.5 times longer than broad together, punctures in elytral striae finer, sparser, less distinctly notching.
