Thorax— Prothoracic lobes deep brown clad with golden narrow- 
curved scales. Mesonotum deep ferruginous, with golden and golden- 
brown narrow-curved scales. Pleurae chestnut-brown with creamy scales. 
Wings with dark brown culex-like scales; first fork cell longer and 
narrower than the second, its base nearer the apex of the wing, its stem 
two-thirds the length of the cell; posterior cross-vein about its own length from 
the median. Coxae light yellowish-brown ; femora with dark brown scales, 
above and laterally, and golden-brown beneath. Knee spots golden-brown 
and also the tibio-metatarsal articulations especially marked in the hind 
egs, base of metatarsus, and bases of first three tarsal joints in hind le^ 
golden-brown, the rest clad with dark brown scales, the front tarsi shewing 
no banding ; ungues large and uni-serrate in front and mid legs. 
Abdomen. Deep brown above, each segment with a well-marked 
golden basal band, and large creamy lateral spots; venter golden. 
Occurrence .—A common jungle variety in some places but very local. 
Remarks. This is one of the largest members of this genus and is a 
vicious biter and feeds so greedily that at times it can scarcdy fly after 
gorging itself. I do not know any mosquito capable of such enormous 
distension as this one. I have no males and have never found the larvae. 
There is no other culex I am acquainted with it could be confused with. 
1 he leg banding is variable. In one specimen the first tarsal joint of the 
rrnd leg has a creamy-yellow band at its base. This mosquito resembles 
Culex Occidentalis but there is no broad band spatulate black scales on the 
head and the prothoracic lobes have no broad scales. It also resembles 
flavifrons but a careful comparison shews points of distinction sufficient 
to constitute it a separate species.
