cell longer and narrower than the second posterior cell, its base nearer the base of the wing than that of 
the latter, its stem not quite so long as the cell ; stem of the second posterior as long as the cell ; posterior 
cross-vein about half its own length distant from the mid cross-vein; halteres with yellow stem and 
slightly fuscous knob. 
Length — 4-5 mm. Habitat. — Gambia. Time of appearance — November. 
Observations — Described from a single perfect male, bred by Dr. Dutton from a larva found in a 
canoe. This Stegomyia very closely resembles Culex univittatus mihi, and might readily be mistaken for it, 
on account of the conspicuous hind tibial banding, but an examination ot the head and scutellum reveals 
flat scales only. The pale head and white shiny scutellum with the brown thorax form also striking 
characters.

A series of this species, which I described from some specimens from Mashonaland, were hatched 
out by Dr. Dutton from larvae taken in the water of ground-nut insect traps, i.e., gutters full of water 
around the ground-nuts. Other specimens were hatched from a small dug-out pool in a rice swamp. 
The specimens hatched out in November and December. 
The abdomen in the $ is much better marked fhan in the original type. A fresh description of 
the male is therefore appended. 
$ . Palpi black, with four white bands, the two apical ones on the base of the last two joints narrow ; 
last two joints with dense tufts of hair, hairs black, except at the apex, where they are pallid ; the 
antipenultimate joint is also hair}' down to near the first white band ; antennae banded black and grey, 
with deep-brown plume-hairs ; proboscis with a narrow white band. 
Thorax as in 9 • Abdomen black, the second to the fifth segments with basal white bands, the sixth 
and seventh have the basal band spreading down each side, the last segment with a basal median white spot ; 
apical hairs golden ; there are also white lateral linear prolongations of the basal bands to each segment ; 
venter covered with pale creamy yellow scales ; legs much as in the 9 ; fore and mid ungues unequal, 
both uniserrated. 
Wings paler than in the 9 ; fi rst submarginal cell longer and narrower than the second posterior 
cell, the bases of the fork-cells nearly level ; stem ot the first submarginal rather more than half the 
length of the cell ; stem ot the second posterior as long as the cell ; posterior cross-vein about its own 
length distant from the mid cross-vein. Halteres pale, but the knob slightly tinged. 
Note. — Fresh specimens are much darker than old ones. The proboscis band is narrower in the 
male than in the female. 
VIII. Culex annulioris. Theobald 
Var. Gtimbiensis. n.V. 
{Mono. Culicid., Vol. i, p. 371) 
Proboscis with white band. Thorax brown with narrow-curved pale brown and grey scales on 
the front two-thirds ; narrow-curved black ones on the hinder third of the mesonotum ; the pale brown 
scales in front form more or less a distinct median line, with a narrow pale scaled line on each side 
and an indistinct darker broad line on each side of the narrow pale line, bounded laterally by mostly pale 
scales ; the scutellum, as in the type, with small black scales at the base of the mid-lobe and grey ones 
on the apical portion ; metanotum bright amber brown. The abdomen is like the type, but the 
triangular basal white spots are very indistinct, but can be detected on each segment by a few white scales 
when examined under the microscope. 
The band on the proboscis is not quite so broad as in the type, and the stem of the first sub- 
marginal cell is very nearly half the length of the cell.
