A Monograph of Culicidae. 



Fort Leavenworth, Kansas ; Westlawn Cem., Ohio (Miss Ludlow) ; 

 Connecticut (H. L. Yiereck). 



Time of capture. — July, August, September (Smith). 



Observations. — Described from specimens sent me by Professors 

 Felt and Smith. It is a woodland species, so far not yet having 

 been found indoors. Specimens have been taken in the northern 

 part of New Jersey in July, August, and September. It is said 

 to attack fiercely, especially below the knees, but no one seems 

 to have been really bitten. 



The larvae occur in woodland ponds, and have been found in 



Fig. 60.
