. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. A Revision of the Bombyliidae (Diptera) of Southern Africa. 667 Length, of wing: about 7 mm. Locality.— Transvaal: Junction of Crocodile and Marico Rivers (Tucker, Feb. 1918). A somewhat narrow-bodied species, recognised by the silvery whitish, comparatively fine and short pubescence, apparent absence of transverse black bristles on segments 2-4 above and laterally and very slender, spinulated proboscis. The fact that the second joints of the palps are much shorter, the proboscis shorter and with more apically rounded labella, that the pubescence is distinctly denser, finer and shorter, and that the black bristles on abdomen are less extensively developed precludes the possibility of its being the <^ of subtropicalis. 2 <$<$ G. tenuirostris n. sp. These two much denuded specimens differ from nivalis n. sp. only in having the silvery or sericeous white pubescence on body and especially on occiput, front part of thorax and in mystax distinctly longer and more shaggy, that on occiput being distinctly longer than length of antennal joints 1 and 2 combined and that on antennal joint 1 distinctly longer; eyes in actual contact above for a distance at least 1J times or even 2 times the length of ocellar tubercle; proboscis slender and long, especially slender in apical part, about 3-4 mm. long, without any visible spinules and with the labella distinctly narrower and sharply pointed apically, with the basal sheath of proboscis below prominent, long and transversely striate. Legs entirely dark blackish brown or black, with 1 spine on middle femora below and about 3-5 spines on hind ones below in apical part; middle tibiae with 2 dark-tipped, pallid, apical spurs below. Hypopygium (text-fig. 194, lateral view and dorso-lateral view of beaked joint) with the basal parts somewhat elongate and narrow, with sparse long hairs above; inner plate at base of beaked apical jo
