THE MOSQUITOES OF THE SOUTHEASTERN STATES aS 
observed devouring small polliwogs. Dyar (50) recorded P. howardii 
from five of the Southeastern States, and it has since been reported 
from Georgia (134), Louisiana (75), and Alabama and Tennessee 
(136). The writers have collected specimens in Louisiana and 
Florida. 
PSOROPHORA FEROX (Humb.) 
(Syn., Janthinosoma sayi D. and K., Culex posticatus Wied., C. musicus Say, ete.; the 
white-footed woods mosquito) 
The white-footed woods mosquito is encountered frequently in for- 
ests and shady spots throughout the South and East and is a severe 
biter. The last two segments of the hind tarsi are white; the other 
tarsal segments and the proboscis are uniformly dark. The waving 
white tips of the hind feet make it easily recognized in the field even 
while on the wing. The larvae breed in temporary rain pools. They, 
too, are easily recognized (except from Psorophora varipes) by the 
unusual length of the antennae. The first notes on the life history of 
this species were published by Morgan in 1902 (128). 
PSOROPHORA VARIPES (Coq.) 
(Syn., P. discrucians H., D., and K. (not Walk.), in part) 
This mosquito breeds in temporary rain pools and is a severe biter. 
It is rare in most of the Southeast, but the writers found it to be 
exceedingly annoying in the woods of northeastern Louisiana. It 
does not fly out into the sunlight to bite, and its presence may be un- 
suspected unless woods are entered. The species has not been ob- 
served to travel far from its breeding places. Horsfall (79) and 
Carpenter (47) have reported it as occurring in large swarms in 
Arkansas following the spring floods. The recorded localities in 
the United States for the species are Clarksdale, Miss., Scott, Ark., 
Charleston, Mo., Wister, Indian Territory (57, 85), Lee County 
(417) and southeastern Arkansas (79), Guntersville (136) and Shef- 
field, Ala. (E. H. Hinman, collector, 1940); and the writers have 
records for Memphis, Tenn., Mound, La., Brunswick, Ga., and Mce- 
David, Ocklockonee, Matecumbe, and Villa Tasso, Fla.; and it has 
recently been reported from North Carolina and South Carolina (table 
1). It is also found in tropical America, where its range overlaps 
that of the related species Psorophora discrucians. 
The species is similar to Psorophora ferox except that the white 
marking on the hind tarsi is limited to the fourth segment and the 
thoracic sealing (fig. 12, G) is somewhat different. 
PSOROPHORA CYANESCENS (Cogq.) 
Psorophora cyanescens is recorded from all the Southeastern States 
except Florida and also from Texas, Kansas, and tropical America. 
It is rare in most of the South, but is reported as very abundant and 
annoying at times in Arkansas (742) and Alabama (136). The adults 
are similar to those of fevoaw except that the tarsi are entirely dark. 
PSOROPHORA HORRIDA (D. and K.) 
This comparatively rare species has a rather wide distribution, 
having been reported from Maryland to Missouri and Texas. In the
