Ungues of the fore legs unequal, both with a single tooth 
towards the base, that of the smaller one minute, a comb-like 
process between ; those of the mid leg very similar, but more 
unequal.

than the second posterior cell, its stem less than half the length 
of the cell ; posterior cross-vein nearly twice its length distant 
from the mid cross-vein. 
Length. — 3 to 4 mm. 
Time of capture .—November and December in Madras; 
February at Quilon; November in Ceylon. 
Habitat. —Quilon, Travancore (James); Madras (Cornwall); 
Ceylon (Bartholomew) (27. 12. 1899). 
Observations .—This species varies to some little extent, but 
not sufficiently to form any definite varieties. Those from 
Quilon are rather paler than those from Madras, and some show 
more thoracic ornamentation than others. In one Madras 
specimen there is a small curious bare horseslioe-shaped patch on 
each side of the thorax. The Madras specimens have also the 
thoracic scales of a more golden tint. Some of the Quilon 
specimens have the yellow abdominal bands with a median 
prolongation. Another noticeable difference is that the upright 
head scales may be dark brown as well as ochraceous, and this 
perhaps might constitute a distinct variety of the species. 
Amongst the material received from Ceylon were a number 
of small banded-proboscis species, which resemble Vishnui in 
all respects, but they are very small and rather darker in 
colour. 
This species closely resembles Culex microannulatus , but can 
be told by its smaller size, its more fawn-coloured thorax, and 
by the ungues of the f having the smaller claw of the fore and 
mid feet toothed, whereas in microannulatus it is simple, and the 
palpi have only three narrow pale bands, not four as in that 
species.
