. Bulletin of the British Museum (Natural History) Entomology. THEREVINE STILETTO-FLIES OF THE ETHIOPIAN REGION 33i with 3-5 ad, pd and pv setae. T2 and t3 with rows of strong setae in all four positions; pv setae of t3 also well-developed, and ad and pd setae of t3 numerous. Femora brownish to almost blackish brown, with predominantly black adpressed hairs, at least on anterior apical surfaces. Tibiae and tarsi brownish to dark brownish. Abdomen. In dorsal view tergites 2-4 with distinct whitish yellow hind-marginal seams. All tergites mostly brownish black and subshining, but the postero-lateral corners gradually becoming more greyish to greyish brown on tergites 2-3. Extreme lateral margin yellowish brown translucent, but this yellowish brown colour practically invisible in a strictly dorsal view. Sternites entirely yellowish brown. Pile moderately long and whitish yellow, only blackish on anterior dark areas of first tergites. Terminalia (Text-figs 426-432). Yellowish brown, and with only pale hairs. Epandrium (Text-fig. 428) rather short. Gonocoxite (Text-fig. 426) broadly truncate posteriorly, with a short projection below. Distal end of dorsal gonocoxal process overhanging posterior margin of epandrium. Stylus comparatively short and stout. Phallic part of aedeagus (Text-fig. 429) rather gradually down-curved; in dorsal view (Text-fig. 430) gradually decreasing in width towards tip. Dorsal apodeme in dorsal view (Text-fig. 430) broad proximally, then narrowing rapidly into a slender distal projection. Tergite 8: Text-fig. 431. Sternite 8: Text-fig. 432. Total length 6-5-6-7 mm. $. Unknown. Material examined. Holotype <$, South Africa: Natal, Karkloof, (B. & P. Stuckenberg) (NM). Paratypes. South Africa: same data as holotype, 3 <$ (B. (NM & ZMC); Natal, Drakensberg, 1780 m, Giants Castle Res., (B. 6- P. Stuckenberg) (NM); Natal, Pietermaritzburg Dist., Swartkop Location, 1 <$, vii. 1959 (B. 6- P. Stuckenberg) (NM). & P. Stuckenb
