AEDES (HETERONYCHA) DYSANOR Dyar. 
Aédes (Ochlerotatus) dysanor Dyar, Ins. Ins. Mens., vol. 9, p. 70, 1921. 
A medium-sized blackish mosquito. Mesonotum yellowish, with 
two narrow separate brown lines, or a single broad median one. 
Abdomen black above, the segmental pale basal bands much nar- 
rowed centrally, or reduced to lateral spots; venter entirely dull 
whitish. Legs black, the femora whitish beneath and a small white 
spot at tip. Wing-scales wholly dark, narrow. 
Indistinguishable in coloration from the punctor variety of punc- 
tor. The species is insufficiently known, having been confused with 
punctor until very recently. The larvae have not been differen- 
tiated and may not be separable. The male genitalia, however, 
furnish a reliable character. The species breeds in the early spring 
pools. 
Distribution.—Southern fringe of the evergreen forests. Possibly 
more widely distributed.
