PSOROPHORA (JANTHINOSOMA) CYANESCENS Coguillett. 
Culex cyanescens CoQuiLLeTt, Journ. N. Y. Ent. Soce., vol. 10, p. 187, 1902. 
A large blue-black mosquito with reddish yellow femora. Head 
and mesonotum sparsely scaled with yellowish, the black integu- 
ment showing; abdomen blue-black, with apical segmental pale 
golden bands; venter pale golden scaled, the terminal segments 
black in the middle. Legs blue-black, smoothly scaled, the femora 
rather conspicuously reddish yellow. Wings smoky, the veins dark 
scaled. 
The larvae develop rapidly in temporary rain puddles. Mr. J. K. 
Thibault says: 
The appearance of this mosquito immediately after rains is so strikingly 
characteristic that even people who never pay much attention to such things 
notice it. They are out in force for several days after a rain and then only 
a few will be found till the next rain. 
It does not enter houses, but is very persistent out of doors, even 
in bright sunlight, and will often pursue a person. It is said never 
to voluntarily quit biting, but must be brushed off. Specimens have 
been seen on a horse for hours, voiding the surplus blood and suck- 
ing fresh. , 
Distribution —Gulf States and Mexican coastal region to Yuca- 
tan; also in Colombia.
