AEDES (HETERONYCHA) TORMENTOR Dyar and Knab. 
Aédes tormentor Dyan and Knap, Journ. N. Y. Hnt. Soc., vol. 14, p. 191, 1906. 
A medium-sized blackish mosquito, the mesonotum with a rather 
narrow Silver line in the middle the whole length. Abdomen black, 
with basal segmental lateral white patches; venter pale. Legs black, 
the femora white below. Wing scales all dark. 
The species is rare, and no notes on the habits are at hand. The 
colorational difference between this species and atlanticus given in 
the monograph seems to be illusory, and the habitats overlap much 
more than there indicated. They may even be coéxtensive. The 
genitalia easily separate the two when males are at hand, otherwise 
the separation is uncertain.

A medium-sized blackish mosquito, the mesonotum brown, with 
a large silvery patch from the front to beyond the middle, not reach- 
ing the sides. Abdomen black, with basal segmental lateral white 
patches; venter whitish, the segments black scaled at their apices. 
Legs black, the femora white below, tibiae with pale reflection be- 
low. The black parts often take a metallic luster. Wing scales all 
dark. Proboscis black. 
The larvae live in temporary ground pools. The adults are some- 
times abundant after rains, but they inhabit woods and thickets, and 
are seldom troublesome, although said to be a persistent biter. This
