white scales, giving it a very marked appearance. 
It resembles to some extent Galex confirmatus, Arribalzaga, 
but can at once be told by the simple ungues, and thus could not 
come in the genus Ochlerotatus formed for C: confirmatus by 
Arribalzaga, although closely related; hence, for this reason, 
amongst others, I have abolished his genus. 
A single specimen sent by Mr. Wray from Taipang, Perak, 
differs from the one described to a slight extent, the abdominal

by Captain James, I.M.S., taken at Quilon, Travancore, S. India ; 
in this the abdominal banding is also swollen in the middle and 
yellow in colour, and resembles the Taipang specimen. 
These I consider form a distinct variety described below. 
Var. cuneatus.
