arr. 1. MOSQUITOES OF THE UNITED STATES—DYAR. 19 
The larvae live in dirty ground puddles, and take rather readily to 
artificial receptacles, such as water barrels. The adults readily enter 
houses, thus making this the common house mosquito of northern 
New York and New England. 
Distribution—Eastern North America, Gulf of Mexico to Canada.

CULEX (CULEX) ERYTHROTHORAX Dyar. 
Culex erythrothoraz Dyar, Proc. U. 8S. Nat. Mus., vol. 382, p. 124, 1907. 
A medium-sized reddish mosquito, the mesonotum red in the integ- 
ument and with fine reddish scales, the abdomen blackish above with 
pale lateral basal segmental spots; venter yellowish scaled. Legs 
blackish scaled, the femora pale beneath. Wing scales narrow, all 
dark. 
The scales on the mesonotum are fine and hairlike. In the male 
genitalia, the tenth sternites have a tuft of spines, two of them on the 
outer side stout and toothlike; mesosomal plate with six to eight 
even teeth between the upper and lower limbs. 
The larvae live in long-standing or permanent ponds containing 
aquatic vegetation and even fish. They rest at the surface among 
Lemna in the reeds and are evidently not readily detected by the 
fish. 
Distribution.—Southern California.
