38 INSECUTOR INSCITI^ MENSTRUUS 



Grahhamia mediolineata Ludlow, Can. Ent., xxxix, 129, 1907. 

 ( ?) Aedes campestris Dyar & Knab. Journ. N. Y. Ent. Soc, xv, 

 213. 1907. 



This characteristic prairie species really does not enter the 

 wooded Canadian zone at all ; but it is found wherever open 

 grassy spots occur, even well into the Rocky Mountains. 



One hundred and forty-three specimens were taken, as fol- 

 lows : Winnipeg Beach, Manitoba, July 4-8, 1918; Wynyard, 

 Saskatchewan, August 13, 1918; Saskatoon, Saskatchewan, 

 August 13, 1918; Banff, Alberta, July 8-26, 1918. 



I am citing campestris doubtfully in the synonymy because 

 I have not been able to recognize it. Mr. Knab says the species 

 is larger; I have large and small curriei, but they do not sep- 

 arate on the character. All mosquitoes vary in size. How- 

 ever, more work in the prairies may clear up the matter and 

 show that the species is really a good one. 



This species, curriei, reappears along the shores of James 

 Bay (Hudson Bay), perhaps as a salt marsh breeder. I have 

 specimens before me from Moose Factory, Ontario, July 26, 

 1918 (H. N. Awrey). A larger form, comparable with cam- 

 pestris, occurs on an island in James Bay, apparently to the ex- 

 clusion of other mosquitoes; Charlton Island, July 19, 1918 

 (H. N. Awrey). 



Dr. Hewitt has been good enough to obtain the following 

 information from Mr. J. M. Macoun, of the Canadian Geo- 

 logical Survey, concerning conditions on the shores of James 

 Bay: "From north of the mouth of the Rupert River all 

 around James Bay to far beyond the Albany, the whole coast 

 is bordered by marshes which in some cases extend many miles 

 inland * * * ^^^^ vegetation in these marshes is chiefly 

 Car ex. Nowhere in Canada that I know of do mosquitoes 

 occur in such numbers as around James Bay and along the 

 west coast of Hudson Bay, where the conditions are very sim- 

 ilar. I was on Charlton Island thirty years ago and do not re- 

 member that any part of the coast there is lov:. There may 

 be some saline marshes, but I do not remember any. The 

 island is wooded, and inland there are many ponds, small lakes
