Notes.—I can detect no structural peculiarities in these small 
_ specimens, yet they look very distinct from our large bifurcatus. 
The only marked differences, save their more fragile appear- 
ance, are the brown abdominal hairs and the more variable 
appearance of the relative lengths of the fork-cells and their 
stems and the difference in the shape of the wings. 
But the differences shown in the wings (figs. 7 and 9) are 
I think sufficient to separate this small Anopheles from the 
European A. bifurcatus.*

ANOPHELES AITKENII. n. sp. (James.) 
A small mosquito of a uniformly dark colour and with 
unspotted wings. ~The following is Capt. James’ description :— 
- ©, Head black, with a few white spindle-shaped scales in

“Thorax dark brown, with 
‘long brown hairs, but without 
scales ; scutellum with long dark

the coxae are pale ; there is no 
trace of banding on any of the joints; the hind first tarsal 
segment (metatarsus) is longer than the tibiae. 
“‘ Hab-tat and cbservations.—Collected by E. H. Aitken on the 
Goa Frontier and in Karwar (Bombay Presidency), in April. It 
differs from <A. ¢mmaculatus in the complete absence of any 
markings on the palpi and legs.” (James.)

from bifurcatus.
