. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. REVISION OF THE BOMBYLIIDAE (DIPTERA) OF SOUTHERN AFRICA 339. Text-fig. 123. Left antenna of <$ Pteraulax flexicornis Bezz., and (on right) left antenna of 6* Pteraulax set aria n. sp. upper apical parts of femora. Wings (text-fig. 122) with the veins dark brownish to blackish brown, usually becoming more brownish at base; first posterior cell distinctly very much longer than discoidal cell; middle cross vein distinctly or much before middle of discoidal cell; squamae (text-fig. 122, below) with fairly dense scale-like hairs or scales on surface; halteres brownish, their knobs brownish above. Head with the space between eyes across level of antennae very much narrower than length of eye from indentation to ante- rior margin; interocular space on vertex in § varying from about 2, to a little more, times distance between outer margins of posterior ocelli; frons distinctly longitudinally depressed in front of tubercle in §; antennal joint 3 (text-fig. 123, left) broadened bulb-like or onion- like at base, slightly more so below; proboscis short, stumpy, confined to buccal cavity, its labella well developed, usually a little longer than basal part of proboscis and with conspicuous spinules; palps subequal in length to antennal joint 3, the basal joint about or nearly 2 times as long as apical joint. Legs with distinct long, fine and relatively dense hairs on front and middle femora below, especially in £; front femora in $ not more developed than in $; middle femora usually without any spines below, but sometimes with a few spines in some $$; hind femora (text-fig. 124) with about 10-12 spines from base to apex below in $ of which the basal 5 or 6 are markedly long and irregularly disposed, with about 6 or 7 shorter spines in $; front tarsi with spicules below fine, short and hair-like on all the joints. Hypopygium of £ (text-fig. 125) with the beaked apical joints rath
