Tvliite scales ; the ord and 4tli segmeuts have at the base a narrow 

 band of long, glittering or bright scales interrupted in the middle. 

 Venter black, with white scales and scattered Avliite hairs ; genitalia 

 rather large, pendulous, set on the left side, reddish and brown, pale- 

 and dark-haired. Legs black, the femora broadly reddish at the base, the 

 4 anterior tibiae dark reddish ; the scales are Avhite, the hairs Avhitish, 

 the spines black ; front tibiae Avith distinct apicules ; middle femora 

 with 2 rather long, hind femora Avith 2 very short spines; hind tibiae 

 Avith a sparse fringe of dark scales outAvardly ; claAvs black. Wings 

 .as in vitvlpennis, Avith a silvery pa tagiuni, but with entirely black basal 

 comb; .terminal loop of the second longitudinal vein much less 

 indicated tlian xisually, almost indistinct, and in consequence the 

 upper branch of the cubital fork is less curved in the middle ; 

 discoidal cell more narrow ; second posterior cell narrow and long, 

 half as broad as the third. Alula long, pale yellowish grey, with a 

 broAvu border and a broad greyish fringe ; axillary lobe very short 

 and broad. 



Villa lasia, Wiedemann (1824). 



A short-haired species of great size, Avitli the Aviugs infuscated at 

 the base and along the costal ceils. 



Descril)ed from the Cape and recorded from South Africa by 

 Fargeau, Serville and Walker. I am referring with doubt to the 

 present species a coujile of gigantic specimens from Bushmauland, 

 Jackal's Water (Cape), October, 1911 (E. M. Lightfoot), measuring 

 15-5-17 mm. in length of body and only 12-13 mm. in length of 

 Aving, while Wiedemann gives only 5 lines. Frons of male as broad 

 as the ocellar tubercle, that of the female tAvice as broad. Clothing 

 of thorax entirely yellow, paler on the pleurae, bristles yellow. On the 

 abdomen there are 5 transverse bands of yelloAvish scaly tomentum — 

 at least in the male. Legs reddish Avith yellowish scales ; femora and 

 tibiae blackened at end, the tarsi likewise. Wings Avith typical 

 venation, no silvery patagia iu the male ; basal comb very large Avith 

 yellow scales ; first posterior cell narrowed at end. 



Villa leucochila, nom. uov. (for V. leucostoma, Wied.). 

 LoeAv's Dipteren-Fauna Siid-Afrikas, PI. ii, fig. 19. 



Very distinct oAving to the broad, broAvn markings of the wings, 

 which fill the whole of the tAvo basal cells. 



Described in 1821 by Wiedemann from the Cape under the name of 

 leucostoma. I change this name, because it is pre-occupied by Meigen,
