white scales ; the Mrd and 4th segments have at the base a narrow 

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

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

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

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

 4 anterior tibiae dark reddish ; the scales are white, the hairs whitish, 

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

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

 with a sparse fringe of dark scales outwardly ; claws black. Wings 

 as in cifi-Ijienittf, with a silvery patagium, but with entirely black basal 

 o>nib: terminal loop of the second longitudinal vein much less 

 indicated than usually, 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 

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

VILLA LASIA, Wiedemauii ( 1824). 



A short-haired species of great size, with the wings infuscated at 

 the base and along the costal cells. 



Described from the Cape and recorded from South Africa by 

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

 present species a couple of gigantic specimens from Bushmaulaud, 

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

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

 wing, while Wiedemauu gives only 5 lines. Frous of male as broad 

 a> the ocellar tubercle, that of the female twice as broad. Clothing 

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

 abdomen there are 5 transverse bauds of yellowish scaly tomeutuui 

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

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

 venation, no silvery patagia in the male ; basal comb very large with 

 yellow scales ; first posterior cell narrowed at end. 



VILLA LEUCOCHILA, nom. uov. (for V. LETJCOSTOMA, Wied.). 

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



Very distinct owing to the broad, brown markings of the wings, 

 which fill the whole of the two basal cells. 



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

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