CULEX TEERITAJs^S 299 



Mr. Grossbeck both report it from rain barrels, each once only. It has occurred 

 in my pails once only so far as our records go. Mr. Brakeley has a pool with 

 cattails where specimens can usually be found until November, and I have taken 

 it myself at the extreme edge of one of the fish ponds at Lahaway. The margin 

 here was very shallow, the pine chats from the edge extending under water to 

 some distance, and here specimens could be found in small numbers. Among the 

 grass in a lily pond, also inhabited by fish, examples are also to be found at 

 almost all times. In fact the grassy edge of large ponds is a favorite place for 

 this species, which seems to escape fish better than most other wrigglers. An- 

 other favorite breeding place is in the quiet eddies or side pools of even rapid 

 streams, where it is usually the only species found. It is frequent in springs 

 and is almost universal in swamp pools formed of spring water. It gets down 

 to the edges of the salt marsh at times and is found in company with salinariiis 

 in the more permanent pools at the edge of the highland. In fact, this is es- 

 sentially an inhabitant of permanent v.'ater bodies and in swamps is the frequent 

 companion of Anopheles. But it may be and is also found in pools which dry 

 out completely at times, and even in rain pools and woodland depressions. It 

 is not a universal breeder, however, like pipiens, and never occurs in such masses ; 

 the la.rvEe are individual in occurrence rather than in swanns." 



Dr. Smith's opinion that Culex territans hibernates in the egg-state seems ill- 

 founded and at variance with what is known of the other mosquitoes 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 undoubtedly come from eggs deposited in 

 the spring by hibernated females. Knab has taken hibernated females in March, 

 in the vicinity of Washington. These were among the crevices of stones over- 

 hanging 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. 



Temperate to subtropical North America.
