. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. 902 ANNALS OF THE SOUTH AFRICAN MUSEUM first posterior cell broadened near apex, but broadly open; discoidal cell broadened apically, but acute at apex, its upper vein rather roundly bent outwards apically, its apical vein slightly or distinctly S-curved; middle cross vein before middle of discoidal cell; second posterior cell apically a little narrower or sometimes as broad as third, its base in $ usually a little more produced than in q*; anal cell narrowed apically; squamae black, dark- fringed; halteres dark brown. Head with the face slightly pyramidally conical, its base very feebly transversely depressed and its apex tending to be slightly indented; buccal cavity also dark, though its anterior rim may be slightly paler in some forms; antennal joint 3 bulb-shaped, attenuated apically, usually shorter or even much shorter than 1 and 2 combined, its style slender, long, as long as or longer than joint. Legs with the front tibiae non-spiculate; hind femora with the spines below usually in two rows; spicules on outer aspect of hind tibiae denser than in rest of rows. Hypopygium of <J (text-fig. 275) with the outer lateral angle of beaked apical joints very prominent, pro- jecting spine-like upwards or apically as seen in side view; ventral aedeagal process slightly broadened apically; lateral struts very strongly developed and large; basal strut markedly developed, broad, racket- shaped and with a pair of wing-like lobes dorsally near its base. In the British, Rhodesian, Trans- vaal and South African Museums. Length of body: about 5^—13 mm. Length of wing: about 7-16 mm. Locality: Gape Province, Orange Free State, Natal, Zululand, Trans- vaal, South-West Africa and Rhodesia. The species appears to be slightly variable not only in size, but in characters such as the presence of white hairs in plumula and base of abdomen, the extent to which the scutellum, pleurae and
