THE MOSQUITOES OF THE SOUTHEASTERN STATES 49 
been reared in water varying in salinity from completely fresh to 
that of sea water. The females become troublesome at times in the 
interior of the Florida peninsula and have been taken in consider- 
able numbers in the vicinity of Orlando, which is about 30 miles 
from salt water. Many larvae were once found in fresh water stand- 
ing on a vacant lot within the city limits of Orlando, the only record 
of the species that the writers have among many collections of 
Aedes larvae from the same locality. In these larvae as well as in 
those of A. sollicitans from New Mexico (mentioned previously) the 
anal gills were as long as the anal segment, instead of in the normal 
budlike form, a condition that may be associated with their develop- 
ment in fresh water. The species was found by Carpenter (4/7) to be 
breeding inland, along with A. sollicitans, in salt water from oil 
wells in Union and Ouachita Counties, Ark., and by E. B. Johnson 
(June 1939) at Oil City, Caddo Parish, La. These locations are 
several hundred miles from the coast. 
The adults are less than medium sized and are dark in color, with 
white rings on the proboscis and tarsi (fig. 13). The mesonotum is 
dark-scaled sprinkled with white, and the wings are dark-scaled. 
The abdomen is without a longitudinal stripe, and the first hind- 
tarsal segment lacks the median white ring of sol/icitans. Southern 
and tropical specimens having the tip of the last hind-tarsal segment 
dark are sometimes classified as variety nzger. Specimens from the 
North Atlantic States usually have this segment entirely white. 
AEDES MITCHELLAE (Dyar) 
This comparatively rare species resembles Acdes sollicitans except 
that the wings are entirely dark-scaled and the first segment of the 
hind tarsi is not ringed with white. It breeds in rain-water pools 
and is a rather severe biter. While it has not been found breeding 
in salt marshes, its range seems to be limited to the Coastal Plain. 
It has been recorded from Mobile, Ala., Victoria, Tex., southern 
Georgia, several places in Florida (40, 85), and Lee County (734) and 
Waycross, Ga. (D. G. Hall, 1981). The writers also have records 
from different places in Florida and have collected the species in light 
traps at Orlando and several points near the coast. It was taken at 
Holly Ridge, N. C. (G. H. Bradley, April 2, 1941). Recently Missis- 
sippi, Louisiana, and South Carolina have been added to the range of 
this species (table 1). 
AEDES TRISERIATUS (Say) 
(The tree-hole Aedes) 
This common woods species has patches of silvery-white scales on 
the sides of the thorax (fig. 12, #7), which give it a rather conspicuous 
appearance. The proboscis and legs are unmarked. It breeds prin- 
cipally in tree holes but to some extent also in water barrels and other 
artificial water containers. It is widely distributed throughout the 
United States and has been reported in all the Southeastern States. 
It is frequently a troublesome biter in the woods. When the larvae 
are found in water barrels associated with those of Aedes aegypti, 
they can usually be distinguished with the naked eye by their darker 
appearance.
