with a small pale median band. Abdomen black, with basal 
white bands. Legs brown, with a trace of pale banding at the

minute basal pale rings, only noticeable in certain lights ; ungues 
equal and simple. 
Wings with typical brown Culex scales, the first sub-marginal 
cell about the same length, but narrower than the second posterior 
cell, its base nearer the apex of the wing than that of the second 
posterior cell, its stem equal to two-thirds the length of the cell ; 
stem of the second posterior cell also about two-thirds the length

Length.—5°5 mm. 
Habitat.—Dindings, Straits Settlements. 
Time of capture —November. 
Observations.—Described from a single 9, perfect save for 
the hind legs, which are partly destroyed. It is closely related 
to Culex microannulatus, but can at once be told by the relative
