GO A Monograph of Culicidae. 
Habitat. —Freetown, Sierra Leone (E. Austen, 8, 1899, and 
9, 1899). 
Observations. — Described from a series of $’s and 9 
brought over by Mr. Austen. It is a very distinct species, 
easily told by its grey-scaled thorax and dusky-black abdomen 
with white lateral spots. Mr. Austen appends the following 
note to this species: “ When at rest the wings of the $ ’s of 
this species overlap at the tip, and so seem to taper to a point. 
Male and female are nearly always found in close proximity, 
resting on whitewashed walls.”
