Natural history. 760 ANNALS OF THE SOUTH AFRICAN MUSEUM In the Transvaal, Rhodesian and South African Museums and Agricultural Dept. of Southern Rhodesia. Length of body: about 9J-i5J mm. Length of wing: about 9 J-i5J mm. Locality: North and North-eastern Transvaal, Southern Rhodesia, South- West Africa and according to Bezzi also in Nyasaland. Easily recognized by its black, slightly violaceous-tinted body, darkly infuscated wings, almost entirely black vestiture and snow-white scaling on sides of abdomen. Very closely related to this species if not identical with it is a species otello described by Szilady from East Africa in 1942 (p. 100, Ann. Mus. Mat. Hungar., xxxv (pars. zool.)). The description is, however, so short and unsatisfactory that it is impossible to arrive at any conclusion without seeing the type Text-fig. 231. Side view of hypopygium and ventral view of aedeagal apparatus of 6* Exoprosopa umbrosa Lw., and right ventral view of detached aedeagal apparatus and side view of basal strut of o* Exoprosopa nephoneura Hesse. Exoprosopa nephoneura Hesse (Hesse, p. 25, Mem. do Museu Dr. Alvaro de Castro, No. 1, 1950.) This species, which I described in my paper on the Bombyliidae of the Museu Dr. Alvaro de Castro in Lourenco Marques, may be, as I stated in that paper, the same as the species pilimana Bezz. from East Africa to which Bezzi referred in his key (p. 235, The Bombyliidae of the Ethiopian Region, 1924), but which was never described by him either previously or subsequently. It is therefore impossible to identify pilimana only from the few descriptive and com- parative references to it in Bezzi's key. Transcribing my description the present species is characterized as follows: Body mainly black; front half of frons and base or basal half of face brownish red or dark ferruginous; postalar calli, greater part of scutellum, hind margins of tergites and sternites (
