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, unbanded and 
unspotted; posterior border-bristles dull-brown; venter rather 
pale. 
Legs unbanded, deep brown, coxae pale, fore and mid femora 
swollen, hind femora narrower, pale beneath ; tibiae and metatarsi 
rather bristly; ungues small, much curved, equal and simple. 
Wings with brown scaled veins 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-A^ein. 
Length. —3*5 mm. 
Time of capture. —June. 
Habitat. —Degama, W. Africa. 
Observations .—Described from a single perfect 9 • It can at 
once be distinguished by the general brown colour, unbanded and 
unspotted abdomen, and by the swollen fore and mid femora. 
It comes very near my Culex longipes in appearance.

I have only seen two specimens, both 9 ’s, showing this character, 
and hence place them provisionally in Culex. C. longipes, mihi, 
comes from the Malay Peninsular.
