Genus Lophocer at omnia. 411 
at the back, brown in front ; some long, straight, dark chaetae, 
paler in median region. Antennae with flaxen plume-hairs, apical 
segments long, dark, not plumose ; palpi long, the two apical 
segments of about equal length, thick, the apical one rather 
narrow towards the tip which is blunt, ochreous basally, dusky 
towards the tips, hair tufts flaxen and brown of moderate size, 
apex of the ante-penultimate segment dark scaled, the penultimate 
with creamy scales on one portion. 
Abdomen : much as in the 5 but with more scattered pale 
scales, hairs brownish. 
Legs darker than in the 9 > the femora show a more distinct 
pale line; fore ungues unequal, both uniserrate, mid unequal 
both uniserrate, hind unequal but simple. 
Wings with the first, third, and fourth long veins dark 
scaled, the costa with many yellowish scales; fork-cells short; 
first sub-marginal longer and narrower than the second posterior, 
their bases nearly level, stem of the former not quite as long as 
the cell, of the latter longer ; posterior cross-vein longer than 
the mid and more than its own length distant from it. 
Length .—5 mm. 
Habitat. —Sudan (H. King). • 
Observations .—Described from a perfect female and two 
males. It is a very marked species easily told by the thoracic 
adornment. It is very variable in colour according to the light 
but has a general yellowish-brown hue. The male ungues are 
very marked; it is the only mosquito I have seen in which 
the hind pair are unequal, and this and the palpi and wing scale 
structure excludes it from any previously described genus.
