the mid ones rather smaller than the

and more nearly equal; hind small, 
equal, and simple. 
Length. — 5 '8 to 6'3 mm. 
Habitat. —Perak (Wray) (22. 11. 
and 21. 12. 1899); Naini Tal (Giles); 
Madras (Cornwall) ; Travancore 
(James) ; Selangor (Butler) (28. 10. 
; Singapore (25. 7. 1899) ; Hong 
Kong ( 8 . 1. 1900); Tinghai, Formosa ( 8 . 1. 1900); Foo Chow

"Walker gives Amboyna as a locality, also Makassar in Celebes, 
Waigiou, My sol, and North Ceram. 
Time of capture. —January in Madras. 
Observations. —This seems to be an abundant Asiatic species, 
being very common from the Straits Settlements along the 
Chinese coastline, and also in Continental India.

The thorax seems to be ornamented in fresh specimens, but 
soon becomes worn. The type is in the British Museum. 
Walker’s type of C. ventralis is also in the Museum collection. 
I have examined them both, and cannot see any differences of 
specific value. A. obturbans varies to some extent in different 
localities, especially in the colour of the scutellar scales; some 
have them all purplish black ; Major Giles’ from Naini Tal have 
them mostly creamy white, others white and black. The pale 
scales surrounding the mesonotum also vary in colour; sometimes 
they are almost white, at others creamy yellow ; there is also a 
slight variation in the position of the posterior cross-vein in 
regard to its distance from the mid cross-vein, as in the common 
European Culex pipiens , but very slight. In some specimens 
there is a more or less distinct line of rather broader creamy
