9 . Head black (Fig. 3^, PL I), entirely covered with flat, black scales ; clypeus, proboscis, 
and palpi black; antennae dark-brown ; basal joint testaceous on one side, dark on the other ; 
eyes golden. 
Thorax black, with rather long, bronzy-brown curved scales, forming a dense matting 
over the black surface; over the roots of the wings numerous jet-black bristles; scutellum 
testaceous in the middle at the base, black at the apex, lateral lobes greyish-brown, mid lobe 
with flat black and grey scales and six (?) black border-bristles ; metanotum blackish ; pleurae 
very dark, with three large patches of white scales. 
Abdomen (c) testaceous at the base, steely-black apically, covered with black scales, each

Legs dark blackish-brown, coxae and trochanters pale-brown ; fore and mid (d) ungues 
equal, uniserrated, hind equal and simple. 
Wings slightly tinged with brown ; veins clothed with dark-brown scales ; fork-cells 
small, the first sub-marginal cell a little longer but no narrower than the second posterior cell, its 
stem equal to about two-thirds of the length of the cell ; stem of the second posterior as long as 
the cell ; posterior cross-vein nearly twice its own length distant from the mid cross-vein. 
Halteres with deep ochraceous stem and fuscous knob. 
Length. — 4*8 mm. 
Habitat. — Bonny. 
Time of Capture. — May. 
Observations. — Described from a single 9 • The specimen was tajcen from a native hut. 
It can at once be told by the entire covering of black scales on the head and the rather long, 
curved, bronzy scales on the thorax and the unhanded abdomen. 
Genus Culex L. (1735) 
(Syst. Nat. 1735) 
Palpi short in the 9 , long in the <J , apical joint of latter usually acuminate, but sometimes 
clavate. Head clothed with narrow curved, upright-forked and broad flat lateral scales ; scutellum 
covered with narrow curved scales ; those on the thorax in three forms, narrow curved, narrow 
hair-like curved, and flat spindle shaped. Wings having the lateral vein scales linear, as a rule, and 
the first submarginal cell generally longer and narrower than the second posterior cell. 
Eggs laid in rafts. 
I have still retained several species in this genus which will have to be removed later.
