Genus Stegomyia. 165 
white band, all the last two tarsals white. Fore and mid ungues 
equal and uniserrate. 
Wings with dark scales, rather dense broad linear lateral 
ones ; the first fork-cell considerably long and a little narrower 
than the second fork-cell, its base slightly nearer the base of the 
Fig. 59. 
Wing of Stegomyia wellmanii. $. n. sp. 
wing, its stem about half the length of the cell; stem of the 
second about two-thirds the length of the cell. Supernumerary 
cross-vein slopeing, the mid parallel to the posterior, the posterior 
about three times its own length distant from the mid. 
Length .—5 *5 to 6 mm. 
Habitat .—Bailunder, Angola, West Africa (Dr. Creighton 
Wellman). 
Time of capture .—March 1905. 
Observations .—Described from 3 5’s. Caught at tent lamp 
8 p.m. The thorax is very marked, and at once separates this 
species from any other Stegomyian I have seen. The type 
specimen shows but scanty abdominal banding, the other two 
show it very plainly, but neither had perfect hind legs. 
The scales on the abdomen of the type had been apparently 
partly denuded, and probably the majority in any case have 
markedly banded abdomens. 
Very near to S. poweri , Theobald, from Natal, but differs in 
(i) the palpi of the y being only white at the apex ; (ii) the 
last two hind tarsals being white; (in) the relative difference in 
length of the stem of the second fork-cell. 
Type in the British Museum.
