A large brown mosquito with large white ringed legs. Mesonotum 
gray at the sides, mixed with brown and a broad red-brown central 
band, the marking indistinct and confused. Abdomen black, with 
white basal segmental bands, also many white scales scattered 
over the surface, the penultimate segment almost wholly white; 
venter white, with a narrow broken central black line. Legs black, 
the femora, tibiae, and first tarsal joint with as many white scales 
as black ones; tarsi beyond the first joint with few white scales, 
and basal white rings, broad on the hind legs. Wing scales black, 
with many white ones, on the costal half of the wing as many white

The larvae occur in ground pools, associated with canadensis, evi- 
dently without relation to flood water. The late John B. Smith 
treated this form well under the name cantans in his Report on 
Mosquitoes (New Jersey Agricultural Experiment Station, 1905). 
It is to be considered a race of stimulans.
