A Monograph of Culicidae. 
Thorax as in the ? . Abdomen broadening out posteriorly ; 
seo-ments black, with basal white bands, which on the second to 
fifth segments spread out in the middle, and the same to some 
extent on the sixth segment ; apical segment dull white scaled ; 
male genitalia and last segment densely golden-haired. Wings 
with the fork-cells rather long; the first sub-marginal cell a 
little longer than the second posterior cell, 
its base nearer the apex of the wing than 
the base of the latter, both cells about 
twice as long as their stems; stem of the 
first sub-marginal cell about equal to that 
of the second, posterior cell, a little the 
shorter if anything. Ungues of the fore legs 
unequal, the larger one uniserrated; the 
hind equal and simple, very small. 
Length .—4 to 5 mm. 
Habitat. —Naini Tal, India (Giles). 
Time of capture. —June and July. 
Observations .— Lt.-Col. Giles sends in his 
collection a large series of a new species, 
for which he proposes the name viridi- 
venter. These mosquitoes are evidently 
common at Naini Tal at an elevation of 
7,000 feet. They present several peculiari¬ 
ties, notably the wing scales, which are very small, the lateral ones 
being extremely thin and hair-like; the banding of the abdomen 
in the J is also very characteristic, and the clear pale venter 
strongly contrasted against the dark tergum. The venation is 
subject to considerable variation, nearly as much so as in 
G. fatigans. In some specimens the base of one cell, in others 
the base of the other, is nearer to the apex of the wing; the 
relative length of the stems and the position of the posterior 
cross-vein also vary. 
Specimens of this species have been presented to the collection 
by Lt.-Col. Giles. 
Regarding this species, Lt.-Col. Giles sends me the following 
note : “ It differs radically from Culex fatigans in habits of life, 
for both this and C. pulcriventer are purely phytophagous, sylvan 
species; though I liberated a number in my sleeping-room, none 
ever attacked me, and they seemed to die for want of vegetable 
food. Moreover, except by accident, they never seem to enter 
houses. In the fresh insect, however, there is no difficulty in 
Pig. 219.
