XV. Laiioconops poicilipes. N. sp. 
Anterior half of thorax with ashy grey scales and chestnut brown ones, the former towards the edge 
of the pale area, posterior part of the thorax dark brown with brown scales. Abdomen black, with basal 
white bands. Proboscis brown, with a pale median band. Pegs deep brown, the femora mottled with 
creamy scales, the tibiae with a row of pale spots, metatarsi and tarsi with narrow basal pale bands, which 
to some extent involve the apices of the preceding segments. 
9 . Head dark brown, with narrow-curved pale grey scales, brown and ochraceous forked scales 
and small flat grey ones at the sides ; antennae brown, basal joint black on the inside, with small white 
scales, and with a grey sheen on the outside, second joint bright testaceous ; palpi black scaled, with 
apical grey scales ; proboscis black scaled, with a pale median band ; clypeus deep brown, with frosty 
sheen. 
Thorax black, the anterior two-thirds clothed with narrow-curved grey scales, palest at the 
posterior edge of this pale scaled area, where the}' form a wavy line ; posterior portion of the mesonotum 
with narrow-curved black and brown scales and numerous black bristles. Scutellum brown, with narrow 
curved dull creamy scales, and with eight black border-bristles to the mid lobe ; pleurae black, with 
patches of white scales and pale creamy hairs. 
Abdomen black, with narrow basal bands of white scales and very large and peculiar white and 
ochraceous lateral projecting scales ; posterior border-bristles golden, short ; venter black, with white 
scales. Legs dark brown, the femora spotted and mottled with pale scales, the tibiae with small creamy 
spots ; metatarsi and tarsi dark brown, with narrow pale ochraceous bands involving both sides of the 
joints. 
Wings with typical brown Culex scales ; surface of the wing with minute bristles ; first 
submarginal cell longer and narrower than the second posterior cell, its base nearer the base of the wing 
than that of the latter, its stem about one-fourth the length of the cell ; stem of the second posterior not 
quite one-third the length of the cell. 
Supernumerary cross-vein not level with the mid cross-vein, a little nearer the base of the wing ; 
posterior cross-vein about two-and-a-half times its own length from the mid cross-vein ; sixth vein rather 
densely scaled. Halteres dusky ochre. 
Length — 6 mm. Habitat — Bonn}', West Africa (Annett), and Gambia (Dutton). Time of 
capture — July (Annett), December (Dutton). 
Observations — Described from a single 9 > somewhat denuded but easily told from all other 
Culicidae by the curious abdominal lateral scales, which are certainly of generic importance. The spotted 
legs give it some resemblance to Culex tigripes, but the banded tarsi and proboscis and general ornamen- 
tation will at once separate it. 
XVI. Mansonia uniformis. Theobald 
Mansonia africanus. Theobald 
{Mono. Culicid. II, p. 180 {Uniformis) and p. 187 {Africanus) (1901) Theo.) 
The collection contains ten specimens of this abundant African Mansonia. They were taken at 
McCarthy Island, in the marsh at the back of the town, and were noticed to bite very viciously. A single 
specimen was also taken in the prison at Bathurst, in October, the others were taken in December. 
Dr. Daniels has shown this Mansonia to be an intermediate host of the Fi/aria. 
After carefully comparing a fresh series of South Indian and Ceylon Mansonia with the ones I 
described as M. africanus {Mono. Culicid. II, p. 187), I am convinced they are the same as the Indian 
M. uniformis. M. africanus must, therefore, sink as a synonym of M. uniformis. The thoracic ornamentation 
very soon becomes destroyed, and the thorax has then a non-ornamented or uniform appearance.
