Var. Umbrosus. Theo. 
Costa blaciC at the base, unbroken by the typical small pale spot. Veins with the dusky scales 
predominating ; the pale scaled areas restricted to the region of the cross-veins and base of the fork-cells 
and on the fifth long vein ; the third long vein dark as in Rhodesicnsis. Wing fringe spotted as in the 
type, but not so prominently. 
IIIb. A. funcstus. Giles 
Var. Subumbrosus. Theo. 
Costa black at the base, unbroken by any pale spot. Dusky scales predominating, but not 
contrasted as in the type with the pale scaled areas. Third long vein pale-sealed in the middle, and pale 
scaled areas also on the fourth, fifth, and sixth. 
IV. Stegomyia fasciata 
(Syst. Antl. 36, 13, 1895. Mono. Culic, I, 289, 1901. Theo.) 
This species is evidently common in Gambia, specimens showing great variation in size were 
taken in Bathurst in numbers : some in native lints, and also in European dwellings. Many seem 
to have been hatched out from larvae taken in a tub of well water, and others from a canoe. This species 
was taken in October, November, and December, and was observed feeding, as recorded elsewhere,* during 
the daytime (4 p.m.) 
V. Siegbmyia sugens. (Wied.) 
Auss. Zweiflug Insec. 54.5 (1828) Wild ; Mono. Culic. 300 (1901) Theo. 
Three $ 's and two £ ' s taken near Bathurst. This Stegomyia can easily be told by the spots on 
the mesonotum and the pale band on the femora near the apex. Hatched out from larvae taken in ground- 
nut gutters during November. 
VI. Stegomyia albocephala. N. sp. 
Head covered with flat dull white scales, a small dusky patch on each side and a posterior semi- 
circular area of dark upright forked scales. 
Thorax deep rich brown covered with scattered golden scales, showing more or less two dark eyes 
like spots ; scutellum with small flat white scales. Abdomen black with narrow basal white bands. Legs 
black, the hind tibiae with a marked apical white band. 
9 . Head brown, covered with dull white flat scales, with a silvery sheen, a small patch of black scales 
on the border about the middle of the eyes, and dull black scales at the sides, posteriorly are black upright 
forked scales, giving the head a dark appearance of semicircular form, in front the upright forked scales 
are yellow. Proboscis, palpi, and antennae deep blackish-brown ; palpi with a trace of a pale band on its 
basal half, two apical joints nearly equal, with black hair-tufts and also black hairs at the apex of the anti- 
penultimate joint. 
Thorax rich deep-brown with scattered golden narrow-curved scales, and showing in certain lights 
two dark eye-like patches on the ground surface ; scutellum covered with small flat shin}' creamy-white 
scales; pleurae brown with patches of grey scales; metanotum deep clear brown. 
Abdomen black with basal white bands which spread out laterally ; venter black with broad basal 
white bands ; densely clothed with long brown hairs. 
Legs black, unbanded, except for a clear, rather broad, white apical band .to the hind tibiae. Coxae 
brown, bases and venter of the femora grey, ungues of the fore and mid legs unequal, the larger uniser- 
ratcd, the smaller (?) hind ungues rather long, curved, equal, and simple. Wings with the first submarginal
