174 THE MOSQUITOES OF NEW JERSEY 



oviposit is not known ; that they perish soon after they are born is in- 

 dicated by our failure to find any of them in winter quarters. 



Taken as a whole, this can scarcely be counted among the really 

 troublesome mosquitoes, and that is fortunate, because it is one whose 

 breeding areas it would be most difficult to control. No other Culex lives 

 in water so shallow as this, and no other is an inhabitant of streams 

 and ponds to the same extent. Anopheles, however, does occur with 

 apicalis in most of its breeding places and any attempt to control the 

 one would naturally affect the other. 



[On the question of hibernation, Howard, Dyar, and Knab (14) say, 

 "Dr. Smith's opinion that Culex apicalis hibernates in the egg state 

 seems ill-founded and at variance with what is known of the other mos- 

 quitoes which lay their eggs in a mass or raft. The larvae appear later 

 than those of any of the forms known to hibernate as eggs and un- 

 doubtedly come from eggs deposited in the spring by hibernated fe- 

 males. Knab has taken hibernated females in March, in the vicinity of 

 Washington. These were among the crevices of stones overhanging a 

 spring in the woods and had undoubtedly passed the winter there. It 

 would seem from Dr. Smith's observations that this species does not 

 seek the shelter of buildings for hibernation and on this account its 

 mode of passing the winter had not been determined."]
