THE MOSQUITOES OF THE SOUTHEASTERN STATES 45 
The writers have taken occasional specimens at New Orleans, 
Mandeville, and Mound, La., and in Orange and Osceola Counties, 
Fla. The species has been reported previously from all the South- 
eastern States except Florida, but records based on female specimens 
alone are questionable. The larval description for the species by 
Dyar and Barret (52) was based on specimens of Culea erraticus. 
The description was corrected by King and Bradley (98). 
CULEX PILOSUS (D. and K.) 
(Syn., Mochlostyrag floridanus D. and K., Culex deceptor D. and K., 
C. agitator D. and K., etc.) 
This small mosquito breeds in shallow, grassy pools, roadside 
ditches, hoofprints, and flooded areas. The eggs are able to with- 
stand drying, a very unusual trait in the genus, and as a rule the 
breeding’ places are temporary. The collected larvae are easily 
recognized by their peculiar wriggling motions and by their habit 
of lying on their backs on the bottom of the container. The tip 
of the air tube has a pair of recurved dorsal spines, which may be 
used for retaining their submerged position. Nothing is known of 
the feeding habits of the adult. The species is common in Florida. 
In addition to the States listed by Dyar (50), it has been recorded 
in Lee County, Ga. (734), Brewton, Ala. (/06), New Orleans, La. 
(EK. S. Hathaway, personal communication), and Charleston, 
S. C. (56). 
Genus AEDES Meigen 
(Syn., Stegomyia Theob., Heteronycha Dyar (not L.-Arr.), Ochlerotatus  L.-Arr., 
Taeniorhynchus L.-Arr., Finlaya Theob., Aedimorphus Theob., Culicelsa Felt) 
With the exception of a few species, including the yellow-fever 
mosquito (Aedes aegypti) and the tree-hole breeder A. triserzatus, 
this genus typically breeds in temporary rain pools, floodwaters, and 
tidal marshes. The eggs are laid singly on damp soil at the edge 
of a pool or in moist depressions, and they are able to survive long 
periods of drying. When such places are flooded with water and 
the temperature is favorable, some of the eggs hatch almost at once 
and often produce enormous broods of mosquitoes; others may not 
hatch until subsequent floodings. With some species, at least, the eggs 
may also be deposited on the water surface, but most of them re- 
main unhatched until the pool evaporates and has again been flooded. 
Some species of Aedes have but one brood each year and are found 
only in the spring, whereas others recur commonly during a rainy 
season. The winter is passed in the egg stage. 
All except five of the species of Aedes included here are placed 
by Edwards (43) in the subgenus Ochlerotatus. The others are 
divided as follows: (Aedes) cinereus; (Stegomyia) aegypti; (Aedi- 
morphus) vexans; (Finlaya) triseriatus, atropalpus. Dyar’s (57) 
classification is similar except that the subgenus 7aeniorhynchus 
(=Culicelsa) 1s recognized by him to include the species taentorhyn- 
chus, sollicitans, mitchellae, and atropalpus.
