A small blackish mosquito, readily distinguished by the white 
abdominal bands being apical on the segments instead of basal, 
though sometimes very narrow. Mesonotum with bronzy brown 
scales and sometimes a pair of light spots near the middle. Pro- 
boscis and legs blackish scaled, the femora whitish beneath. Wing 
scales narrow and hairlike, wholly dark. 
The male genitalia have the mesosomal plate simple, the pair 
united by a bridge in a characteristic manner. Lobe of the side- 
piece with two capitate rods, three flattened setae and three normal 
setae. 
The larvae occur in grassy marshes, and can be found all summer. 
The adults do not bite warm-blooded animals, but have been ob- 
served attacking frogs. 
Distribution—North America, from Mexico to Canada; Europe.
