1922] Matheson and Shannon: ATosquito Records 163 



Anopheles walkeri Theobald. 



This anopheline is widely distributed in Eastern North 

 America, but is rarely taken or seen in collections. There are 

 no records of it having ever been taken in New York State. 

 On July 3, 1921, five specimens, while in the act of feeding, 

 were collected at North Fair Haven. A single specimen was 

 taken on August 5, at Duck Lake, while in the act of biting. 



Wyeomyia smithii Coq. 



Wyeomyia smithii Coq. is well known to be an obligate 

 inhabitant of the pitcher plant {Sarracenia purpurea) and 

 practically all that is necessary to get the mosquito is to find 

 the plant. 



Pitcher plants are well known to occur in New York State, 

 but to date there have been no records published of the occur- 

 rence of the mosquito in our boundaries. 



The sphagnum bogs of McLean, N. Y., contain numbers 

 of pitcher plants and during June and July, when these plants were 

 examined, many of the larvce of this unique mosquito were 

 found in them. Only plants containing an abundance of fluid, 

 as yet uncontaminated by decaying insects, were inhabited. 



The swamp lying close to Duck Lake, N. Y., is an excellent 

 region for pitcher plants, where they flourish in great abundance. 

 The larvas of Wyeomyia smithii occur in great numbers, and 

 during the middle of August, when this region was visited, 

 large numbers of the larvse could be obtained from the plants. 

 The adults were also observed, flying amongst the low 

 vegetation. 



Successful rearings were easily obtained by isolating the 

 larvae in vials and using the fluid from the plants as the rearing 

 medium.
