Genus Culex. 7 3 
with creamy-yellow basal bands, the last segments with a dull 
brassy tinge ; densely hairy. 
Legs, especially the mid and hind pair, with the femora, 
tibiae, and metatarsi bristly; fore ungues very unequal,. the 
larger curved, the smaller nearly straight, the former with a 
large tooth towards the middle, the smaller with a small one 
near the base; hind ungues equal and simple. 
Length. —4’5 to 5 mm. 
Habitat.-— Durban (Christophers) (13. 2. 1899); Salisbury, 
Mashonaland (Marshall) (79); Straits Settlements, Perak 
(Wray) (22. 11. and 21. 12. 1899). 
Time of capture .—January in Durban; March in Mashonaland. 
Observations .—Evidently a widely distributed mosquito, for 
it certainly occurs in the Malay Peninsula, as well as in 
Africa. It is a very distinct species, readily told by the orange- 
scaled areas on the mesonotum. The $ palpi are very peculiar, 
and I am not sure that they are not of generic value in this 
case; in a few other male Culex that I have examined the joints 
have also been so reduced; in the 9 antennae we likewise see 
a striking peculiarity in the swollen second joint. It will 
probably have to be removed to a separate genus from Culex. 
The 9 from Perak differs only in having the palpi all 
black instead of being orange at the base.
