The larvae live in holes in rocks along streams and the edges of lakes. 

 The winter is passed in the egg state, the eggs fastened on the side of the 

 rock. In summer generations, the eggs are scattered loosely. The adults 

 are good biters in the vicinity of their breeding places which are neces- 

 sarily very restricted, so that the species is never more than locally 

 common. The mating habits of the males are unknown. 



Distribution,: Atlantic coast region from Virginia to New England; 

 possibly in Mexico {epactiiis Dyar & Knab), and to be expected in

Culex varipalpus Coquillett, Can. Ent., xxxiv, 292, 1902. 

 Taeniorhynchus sierrensis Ludlow, Can. Ent., xxxvii, 231, 1905. 



A smi^U blackish mosquito with white-ringed legs. Mesonotum dark 

 brown, ornamented with a patch of light golden scales in front and a 

 narrow line of the same from the lateral groove backward. Abdomen 

 black, with basal segmental even white bands; venter whitish^^caled. 

 Legs black, the fembra w^ite below; tips of femora and tibiae and the 

 apices of the tarsal joints silvery white, involving the bases of the joints 

 to a less extent; rings narrow, except on the hind legs, where they are 

 broad, involving the whole of the last joint. Wing-scales wholly dark, 

 thick and dense. 



The larvae live in the water in holes in tree-trunks, occasionally in 

 artificial receptacles. The winter is passed in the egg state; it is not 

 known whether there is more than one annual generation!. The females 

 occasionally occur in ann,oying numbers in old forests, but are usually 

 rare. The males form little swarms in the day time about some stationary 

 warms-bloodied animal, and rniate with the females as these come to bite. 



Distribution: P/acific coast region from southern California to British 

 Columbia.
