Genus Culex. 457 



dull white. Abdomen deep brown, banded with broad yellow 

 basal bands. Legs deep brown, unbanded. Wings with both 

 fork-cells long. 



9 . Head brown, with rather large narrow-curved creamy 

 yellow scales and deep brown upright forked scales, flat pale 

 creamy lateral scales and somewhat paler scales around the 

 eyes ; clypeus, palpi and proboscis brown, the clypeus paler than 

 the others ; antennae brown, segments long and thick, pilose on 

 the internodes, hairs deep brown. 



Thorax pale brown, uniformly clothed with dense irregularly 

 disposed dull golden-brown narrow-curved scales, giving a fawn- 

 coloured hue when viewed under a hand lens, chaetae deep 

 brown ; scutellum paler brown, with paler narrow-curved scales 

 and seven deep brown border-bristles to the mid-lobe ; metanotum 

 deep brown ; pleurae dull white, with a large deep brown spot 

 above in front, and three smaller ones behind in the same line, 

 and one below the large one in front. 



Abdomen deep brown, with broad yellow basal bands. 



Legs deep brown ; coxae pale, femora paler at the base ; 

 ungues small, equal and simple. 



Wings with both fork-cells long, the first sub-marginal very 

 little longer and narrower than the second posterior cell, its base 

 nearly level with that of the latter, its stem not quite half the 

 length of the cell ; stem of the second posterior a very little 

 more than half the length of the cell; posterior cross- vein not 

 quite twice its own length distant from the mid cross-vein ; the 

 main stem of the fifth vein dark \ the sixth situated close to the 

 fifth, much more so than is usual in Culex ; halteres with pale 

 stem and fuscous knob. 



Length. — 7 mm. 



Habitat. — India (Dr. Christophers). 



Observations. — Described from a perfect $ . This is un- 

 doubtedly a true Culex, although the sixth vein is abnormally 

 near the fifth. The uniform fawn-coloured thorax, and the long, 

 nearly equal fork-cells and the large size will easily render it 

 distinguishable from the allied species coming around C. pipiens. 

 The dull white pleurae, with the large and small brown spots in 

 a line and a small one below the first large one of the Rve will 

 also help in its identification.
