gray scales around the margins and a pair of dots in the middle. 
Abdomen black dorsally, banded or with a row of small segmental 
spots or none, lateral basal white spots, the venter pale, banded with 
black on the posterior borders of the segments. Proboscis with a 
white ring in both sexes. Tarsi ringed with white at both ends of 
the joints, narrowly so, even on the hind legs. Wing scales fine, all 
dark. 
The larvae occur in ground pools, by preference dirty ones, also in 
containers even of small size, having been taken in coconut husks and 
bamboo joints. The water in these is especially foul. The larvae 
are readily recognized by the peculiar short air tube, suggesting that 
of an Aédes. 
Distribution.—Tropical America, Mexico, Central America, Ecua- 
dor, the Guianas, Antilles and Florida Keys.

A dark-brown mosquito, rather over middle size, the abdomen 
wholly blackish above, without white bands. Proboscis and legs 
blackish, the femora narrowly whitish beneath. Mesonotum with 
dark brown scales and conspicuous dark setae. The abdomen has 
pale triangular basal segmental spots on the sides, the venter pale, 
with faint darker bands at the apices of the segments. The wing 
scales are long, dense, and broader than usual, being ligulate, rather 
than hairlike, all dark brown. 
The male genitalia have the mesosome membranous and paired, 
with an outwardly directed basal chitinization. Sidepiece without 
lobe, the basal excavation with three stout setae at its tip. 
The larvae live in small collections of permanent water in swamps, 
and are very peculiar in passing the winter as full-grown larvae 
under the ice. The eggs appear to be laid singly on the surface of 
water in the summer time. No observations are on record of the 
biting habits of the adult. The mosquito is rare, and in no way 
troublesome. 
Distribution.—Gulf of Mexico and Atlantic watershed to northern 
New York and New Hampshire, presumably in southern Canada.
