Genus Culex. 403 



10 teeth on each side of apex, largest towards the base. Scales of 

 eighth segment of from 28 to 35 in each patch, the scales with 

 fine apical fringe; pecten of siphon of a double row of 17 to 21 

 spines ; anal gills slender, a little longer than the ninth segment. 



Dr. Dyar states that the eggs are laid in patches on the rock 

 side of the pot holes where the larvae occur, usually at a time 

 when the water is low, and they pass the winter in this condition. 

 They hatch in March irregularly and grow slowly, the adults 

 maturing late in April. 



The eggs are black, elliptical, and coarsely reticulated. Those 

 laid in spring hatch in three days. There are several broods. 

 The larvae feed on green Protococeus.
