REVISION OF THE BOMBYLIIDAE (DIPTERA) OF SOUTHERN AFRICA 925 glassy hyaline; base, costal cell (to end of false vein) and more or less basal half of first basal cell opaquely yellowish, without any visible spot-like infuscations on cross veins in basal half; veins dark brown; enclosed supernumerary sub- marginal cell only a little broader apically than basally, its apical vein oblique; middle cross vein just before middle of discoidal cell; the latter subacute or more subtruncate apically, not produced, its apical vein straight or almost so; squamae pallid or whitish, white-fringed; halteres yellowish brown or brownish, with almost white knobs. Head with antennal joint 3 elongate-conical, gradually narrowed from broad base, its style less than half, sometimes only about a third, length of joint; face shortish, distinctly much less than half length of frons (from between antennae to front ocellus). Legs without any distinct spicules on front tibiae; longish scales on hind tibiae very much shorter than spicules. Hypopygium of <$ as shown in text-fig. 281, with the beaked apical joints not so curved upwards as in vittata, coleoptrata and nigripennis (cf. text-figs. 278-80); lateral struts strongly developed and broad- ish and ventral aedeagal process as in figures. Length of body (of specimens) Length of wing (of specimens). Text-fig. 281. Side view of hypopygium of $ Ligyra sisyphus (Fabr.) and ventral view of aedeagal apparatus of the same species. about 11 J-13 mm. about 11^-14 mm. Locality: Belgian Congo (Urundi Territory): Rumonge (Francois, 25 May 1949) and Rutana (Francois, 22 May 1950) and, apart from Tropical West Africa, also Abyssinia, Kenya and Uganda (vide Bezzi).
