and marshes. The flora is identical with that of the mainland 

 far from the sea." 



Aedes aurifer Coquillett. 



Culc.v aurifer Coquillett, Can. Ent, xxxv, 255, 1903. 

 This species should occur in the margin of the Canadian 

 zone, but there are no Canadian records as yet. Besides the 

 data in the monograph, which include Dublin, New Hamp- 

 shire, and Elizabethtown, New York, I have undoubted aurifer 

 from Minneapolis, Minnesota, July 2-3, 1903 (K. Taylor). In 

 all of theseThree localities punctor occurs, showing them to be 

 well within the Canadian zone. 



Aedes triseriatus Say. 



Ciilex triseriatus Say, Journ. Acad. Nat. Sci. Phil., iii, 12, 1823. 

 Finlaya (?) nigra Ludlow, Can. Ent., xxxvii, 387, 1905. 

 Aedes triseriatus var. hendersoni Cockerell, Journ. Econ. Ent., 

 xi, 199, 1918. 



This tree-hole breeding species probably does not come in the 

 Canadian zone, although it reaches very close to it and may 

 occur in the southern fringe. The northern spruce forests do 

 not form holes holding water, and so the characteristic breed- 

 ing places of this species are absent. 



Aedes atropalpus Coquillett. 



Culcx atropalpus Coquillett, Can. Ent., xxxiv, 292, 1903. 

 This rock-hole breeding species may occur in the Canadian 

 zone, in the eastern part. No records are at hand. 



Aedes varipalpus Coquillett. 



Culex varipalpus Coquillett, Can. Ent., xxxiv, 292, 1902. 

 Taeniorhynchus sierrensis Ludlow, Can. Ent., xxxvii, 231, 190S 



This western tree-hole species occurs in the Kootenai region 

 of the Rocky Mountains, but has not yet been recorded from 

 the main range.
