100 A Monograph of Culicidae. 
This is called by Theiler the Black Anopheles of Pretoria. 
Probably another species closely related—One specimen in the 
series has the last palpal joint black at the base—so there are 
four, not three, pale bands ; the wings are also darker scaled, the 
third long vein being entirely black. But, until I see more 
material and the larvae, I scarcely like to separate it, as I can 
detect no structural differences. 
Larva of Nyssorhynchus Pretoriensis. 
The larva at once separates this species from the Indian 
relative, although adult characters are so near. 
The frontal hairs are all simple (fig. 58, b), the outer ones 
very short, the median long and thin.

NV. Pretoriensis. n. sp. 
The antennae (a) have apparently no lateral tuft, but two 
terminal spines, one longer than the other, and a branched 
intermediary plume-hair. 
NyssorHyNcHUS WILLMORI. n. sp.. James. 
The following is Captain James’s description :— 
Palpi with three white bands. ‘Thorax dark brown, covered with 
white scales and hairs. Abdomen brown, with many golden scales and 
hairs. Legs deep brown, thickly speckled with white; the last tarsal 
segment of hind leg pure white. Wings spotted.
