Genus Stegomyia . 
.305 
Wings covered along the veins with brown scales and with 
brown fringes. Halteres white, with black knobs. 
Length. —4*5 to 5 mm. 
£ . Head as in the 9 i proboscis dark brown ; palpi black, 
with the bases of the second and third joints broadly banded 
white, the fourth and fifth joints with small white basal bands 
ventrally. Antennae with brown 
plumes, a distinct white spot at 
their base. Thorax as in the 9 > 
but the white band at the root of 
the wings more distinct, and with a 
white patch of scales in the middle, 
near the head, which looks almost 
like the remnant of a median white 
line; a line of white scales also on 
the edge of the scutellum. Abdo¬ 
men brownish-black above, with two 
white spots on the last segment but 
one, which is laterally enlarged—the 
whole abdomen with long, bright 
yellowish-brown hairs, laterally with 
distinct white patches of scales. Legs, &c., as in 9 • Fore and 
mid ungues unequal, both simple, the larger one of the mid legs 
straighter than that of the fore legs; hind ungues small, equal, 
and simple. 
Length. —4*5 mm. 
Habitat .—Sierra Leone (Austen, September, 1899) (99, 267); 
Mashonaland (Marshall) ; Lagos (Strachan) ; Old Calabar 
(Annett); Zomba, B.C.A. (Daniels and Gray). 
Observations .—A very distinct species, which I cannot trace 
to any previous description. The two white lateral thoracic 
oblique bars and peculiar leg banding should identify it at once. 
It seems to be a very common species in the above-named parts 
of Africa. It may be easily confused with S. fasciata, but the 
£ ungues at once separate it.
