Genus Culex. 
27 
bright deep brown, with golden-brown border-bristles, apparently 
eight to the mid lobe, and with narrow curved hair-like black 
scales, which also occur on the mesothorax just in front of the 
scutellum ; metanotum shiny chestnut-brown, rather keeled in 
the middle ; pleurae slaty-grey and rich ochraceous, with a patch 
of creamy scales. 
Abdomen deep ochraceous-brown when denuded, covered 
with rather narrow brown scales with dull violet reflections, 
bases of the segments with broad creamy-yellow curved bands, 
appearing golden in some lights, the second to fifth segments 
with white lateral median spots, the sixth and the seventh with 
the white spots almost apical, last segments yellowish with 
golden bristles ; abdomen hairy with brown hairs; male geni¬ 
talia with the basal joint blackish, with long golden hairs, 
claspers long, golden-yellow ; venter golden scaled, the segments 
with narrow black apical bands. 
Legs deep brown, with an ochraceous tinge, knee spot and 
tibio-metatarsal joint yellow on each side of the joint; hind legs 
with the last two tarsi and apex of the antepenultimate one 
white ; the tarsal joints look very pallid in some lights under the 
microscope: fore and mid ungues rich brown, unequal, both 
uniserrated ; hind ungues equal and simple. 
Wings with a yellowish tinge; fork-cells short, the first 
sub-marginal a little longer and narrower than the widely 
expanded second posterior cell, its stem about one and a half 
times the length of the cell, its base a little nearer the base of 
the wing than that of the second posterior cell; stem of the 
latter cell about twice the length of the cell; mid and super¬ 
numerary cross-veins meet almost in a straight line; posterior 
cross-vein long, only half its length distant from the mid cross¬ 
vein. Halteres with a pale stem and fuscous knob. 
Length .—6 mm. 
Time of capture. —July. 
Habitat. —Bonny, West Africa (Annett). 
Observations .—Described from a single £ in perfect condition 
taken by Dr. Annett. This is quite the most beautiful Culex 
I have seen; it can readily be told by the brilliant plumes of the 
antennae and the white hind tarsi. The colours vary in different 
lights to some extent, the creamy-yellow bands of the abdomen 
appearing golden in some lights when examined with the 
naked eye. 
In many respects this species resembles Van der Wulp’s
