. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. A Revision of the Bombyliidae (Diptera) of Southern Africa. 645 (Holotype); Kaotwe ( Kal. Exp., 8-12/4/30) (Allotype); Damara Pan ( Kal. Exp., 15-21/4/30). This species is easily recognised by its luteous or pale yellowish tibiae and pale brassy yellowish appearance of the hair on abdomen above, due to dense depressed brassy pubescence, especially in $ and also by the cretaceous white hairs and bloom on pectus and pleurae. From leucophys it differs in having pale yellowish tibiae, paler yellow and less golden pubescence above, less extensively yellowish hairs on antennae below and with no black bristles towards apex of venter. The species seems to be variable in size and colour, some specimens being smaller and some with paler and more whitish pubescence. In the British Museum there is a single ^-specimen, from Worcester (Turner, 17-31/8/1928), which does not differ structurally and even in colour from the Bechuanaland specimens and it cannot be referred to any other species but this. The species thus appears to be widely distributed in the drier parts of the Karoo and Bechuanaland. 1 <$ 3 $$ G. kalaharicus var. venustus Hesse. (P. 169, Ann. Trans. Mus., vol. xvii, 1936.) These specimens from Bechuanaland constitute a distinct variety, differing from the typical form in having distinctly paler and more.
