Thorax, deep rich brown with narrow-curved bronzy scales, amongst which are scattered narrow- 
curved bright golden ones, grey ones in front of the roots of the wings and in front of the scutellum ; 
numerous long black bristles over the roots of the wings and on the posterior part of the mesonotum ; 
prothoracic lobes brown with outstanding creamy narrow-curved scales, and a series of stout black 
orwardly projecting bristles. Scutellum, testaceous with narrow-curved grey scales wider than those of 
the mesonotum ; on the side lobes, border bristles deep brown in two series ; on the median lobe, six 
larger ones, and numerous smaller ones behind ; the mid lobe covered with loose flat grey and dusky 
scales ; pleurae, brown, with patches of grey scales ; metanotum, testaceous brown. Abdomen covered 
with black scales, the segments with narrow white basal bands which spread out laterally to form spots ; 
the first segment is pale testaceous at the base with a large apical median patch of black scales, and a few 
grey ones at the sides, and numerous long brown hairs ; posterior borders of the segments with pale 
golden border bristles of two alternating sizes ; venter with very broad grey basal bands and narrow 
apical dark ones. 
Legs, deep brown ; bases, paler ; femora, white beneath ; fore and mid legs without any trace of 
banding, but the hind tibiae have an apical white band and are longer than the hind metatarsi ; femora, 
tibiae and metatarsi with bristles which are pale golden in some lights, brown in others. Fore and mid 
ungues equal, uniserrated ; hind, equal and simple. 
Wings with the veins clothed with brown scales, rather dense and large on the second long vein 
and also on the basal areas ot all the veins, longish lateral ones on the hind and apices of the fourth and 
fifth ; first submarginal cell longer and narrower than the second posterior cell, its stem about one-third 
the length of the cell, its base nearly level with the base of the second posterior cell ; in the second 
posterior cell the stem is about two-thirds the length ot the cell ; posterior cross-vein about one and a 
half times its own length distant from the mid ; halteres, pale ochraceous. 
Length, \ to y 5 mm. 
$ Palpi brown, much shorter than the proboscis, the last two joints short, of nearly equal length, 
darker at their tips than at the base, apex of the antepenultimate joint slightly expanded, also darker than 
the rest ; traces of a very narrow pale band ; hair-tufts brown ; proboscis deep brown, longer than the 
palpi ; antennae with flaxen brown plumes, banded brown and grey ; head like the 9> only rather more 
narrow-curved scales running into the crown ; thorax and abdomen with similar ornamentation ; fore 
and mid legs with unequal ungues, the tore both uniserrated, the mid with the large simple, the smaller 
uniserrated, hind equal and simple ; genitalia with the basal lobe very bristly ; claspers slightly sinuous. 
Length. — 4 to 4/5 mm. 
Habitat. — St. Louis, Senegal (Drs. Dutton and Todd). 
True of Capture. — May and September. 
Observations. — Described from a large number ot dry and spirit specimens. In habits it bears 
some resemblance to Democerites cancer (Thkobald). They breed in crab holes, where the larvae were 
taken as deep down as three feet three inches. The adults were caught in and around the crab holes, 
in mangrove swamps, near the race course, at St. Louis, also in the bush by Oyster Creek, Bathurst, and 
in an old tub in a garden at St. Louis. 
Culex duttoni. — From old sand garden pool. Sor St. Louis, May 21, 1903. Bred trom pool dug 
in sand to obtain water for gardening purposes, about ten feet deep ; diameter, twelve feet, now disused, 
now only three inches at bottom. Sor St. Louis, May 22, 1903. Garden tub. Bridge puddle. Bred 
in laboratory, June 2. 
Culex luteoleiteralis, v.ir. Pallida (n.v.) — Caught in marsh behind Subenta, January 18. 
Culex lutcolatcralis, var. alio thorax (n.v.) — Caught in bush near Inkutu, January 18. 
Culex tigripes. — Hatched out from larvae taken in tub, in garden, and in hospital. St. Louis, 
May 31, 1903. Tub in garden, Sor St. Louis.
