beyond it, in the east as far south as New Jersey, while its' westward 

 limits are not yet known ; A.fitchi, Felt & Young ; A. riparms, D. & K., 

 described from Winnipeg, the larva being unknown ; A. fletcheri, 

 Coq., a species supposed to be peculiar to the prairies, but which 

 also occurs in the forest ; A. canadensis, Theo., not confined to the 

 Canadian zone, but extending in the east to Florida and being wide- 

 spread in the northern forests, where the larvae frequent open pools 

 and roadside ditches ; A. vexans, Meig. , widely distributed in temperate 

 regions in both Europe and America ; A. cinereus, Meig., a species 

 widespread in north temperate regions in Europe and America ; 

 Culicella dyari, Coq., a species fairly closely confined to the Canadian 

 region and not extending far beyond it, the males being strongly 

 attracted to light ; Cidex restuans, Theo. , found rarely in the forested 

 regions in the east, but ranging well to the south along the Atlantic 

 seaboard, the larvae inhabiting open pools in company with Aedes 

 canadensis ; Anopheles occidentalis, D. & K., widely distributed in 

 the western United States, following the Canadian forests eastward, 

 but rare in the north ; Taeniorhynchus {Mansonia) perturbans, Wlk., a 

 widespread species found in the timbered country in the lake region ; 

 Theobcildia [Cidiseta) impatiens, Wlk., a species characteristic of the 

 Canadian fauna, but extending to the Pacific coast, and the mountains 

 of California. 



Species entering the margin of the Canadian zone include :—Theo- 

 baldia {Cidiseta) inornata, Will., widely distributed throughout the 

 United States, entering the Canadian region only in mild, open 

 localities ; T. [C.) incidens, Thoms., a Pacific coast species entering 

 the Canadian region only in the Rocky Mts. ; C. alaskaensis, Ludl., 

 a northern species entering the Canadian zone in the Rocky Mountains ; 

 Aeies pullatus, Coq., abundant in the higher Rockies, breeding in 

 open muddy pools near lakes and rivers ; A. hirsnteron, Theo., occur- 

 ring at the eastern limits of the Canadian fauna and extending well 

 to the south; A. vinnipegensis, sp. n., the male and larva being 

 unknown, which occurs in the eastern wooded prairies ; A. trichurus, 

 Dyar, a western form, the corresponding eastern one being A. cinereo- 

 horealis, Felt & Young, while A. poliocJiros, sp. n., is suggested for the 

 intermediate form from Manitoba ; Culex saxatilis, Grossb., widely 

 distributed in forested regions from ocean to ocean and from Canada 

 to Mexico, the larva occurring at Winnipeg Beach, Manitoba, in 

 roadside puddles : Aedes spenceri, Theo., a strictly prairie species ; 

 and A. curriei, Coq., a tharacteristic prairie species which does not 

 enter the wooded Canadian zone at all, but is found wherever open 

 grassy spots occur, even well into the Rocky Mountains.

 Coq. (Diptera, Culicidae). — Insecutor Insciiiae Menstruus, Wash- 

 ington, D.C., vii, no. 1-3, January-March 1919, pp. 63-64. 



The larvae of Aedes bimaculatus are recorded from a " sink hole " 

 in a thicket at the edge of the city of Charlotte, N. Carolina. These 

 larvae were found lying almost parallel to the surface of the water 

 in a position formerly regarded as characteristic of Anopheles and 

 Vranotaenia only. This species has previously been taken in Texas, 

 Louisiana, Mississippi and Arkansas, but not in N. Carolina.
