$ . Palpi ochraceous, covered with dark-brown scales, a small pale band near the base, 
the last two joints with dense black hairs, and also on one side of the apex of the antepenultimate 
joint ; antennae banded, brown and grey, with deep flaxen-brown plumes; proboscis deep brown, 
apex testaceous. Abdomen narrow, expanding apically, the fourth and fifth segments with basal 
white bands, the sixth, seventh and eighth with pale bands expanded laterally, the ninth mostly 
white, moderately hairy. Fore and mid ungues unequal (Fig jb, PI. II), the larger one un- 
iserrated, the smaller with a tooth near the base, hind equal and simple. 
Length. — 5 to 5 "3 mm. 
Time of capture. — August. 
Habitat. — West Africa. 
Observations. — Described from five specimens in this collection. A very distinct species 
with hoary scaled thorax, which has a dull golden tinge however in some lights, the banding 
of the abdomen and the form of the cross-veins are also characteristic. 
XIV. Culex invenustus. Nov. sp. 
(Fig. 8 and 9, PI. II.) 
Thorax dark-brown ; abdomen black, unhanded and unspotted. Legs dark-brown, with 
pale-grey bases, fore and mid femora thick. 
$ . Head (Fig. 8b, PI. II) almost black, with narrow ochraceous-grey curved scales, 
blackish and brown, thin, upright-forked ones, flat white scales at the side, and a narrow white 
border round the eyes ; eyes black ; palpi short, dark-brown ; proboscis rather short, dark-brown 
testaceous at the tip; antennae dark-brown, basal joint black, last two joints very hairy ; clypeus 
black ; thorax dark steely-black, covered with small, dull bronzy-brown, flat scales, forming a 
complete layer ; when denuded the thorax shows three narrow parallel black lines ; scutellum 
greyish-brown, with narrow curved pale scales and black border-bristles ; metanotum dark-brown ; 
pleurae ochraceous brown, slightly darker in front. 
Abdomen deep blackish-brown, narrow, unhanded and unspotted ; posterior border-bristles 
dull-brown ; venter rather pale. 
Legs unhanded, deep-brown, coxae pale, fore and mid femora (Fig 9, PI. II) swollen, 
hind femora narrower, pale beneath, tibiae and metatarsi rather bristly ; ungues small, much 
curved, equal and simple. Wings with brown scales of typical Culex form ; fork-cells moderately 
long, the first sub-marginal considerably longer, but no narrower than the second posterior cell, 
its stem about one-fourth the length of the cell, its base nearer the base of the wing than that 
of the second posterior cell, stem of the latter, half the length of the cell ; posterior cross-vein 
nearly twice its own length distant from the mid cross-vein. 
Length. — 3*5 mm. 
Time of capture. — June. 
Habitat. — Degama, West Africa. 
Observations. — Described from a single perfect 9 • L can at once be distinguished by the 
general brown colour, unhanded and unspotted abdomen, and by the swollen fore and mid femora. 
It comes very near my Culex iongipcs in appearance. 
The much swollen femora are probablv of generic value, but I have only seen two 
specimens, both $ 's, showing this character, and hence place them provisionally in Culex.
