I am greatly indebted to Mr. F. W. Edwards, of 
the British Museum (Natural History) for examining 
the three new species of Culex, and confirming my 
opinion that they were new to Science. Also to Mr. 
Eugène Kassessinoff, who executed the drawings re¬ 
produced herewith. 
For the purpose of the following keys, it has 
been thought advisable to avoid the use of all those 
characters which, however important scientifically, 
require the use of a high magnification, and (in the 
case of the key to the adults) to attempt to provide an 
accurate means of identification necessitating only a 
good pocket lens. All the characters employed, except 
where specifically stated, are applicable to both sexes. 
For the certain identification of the larvae, a low 
powered microscope is however essential.
