224 ORTHOPTERA OF NOVA SCOTIA. — PIERS. 



nominal species in 18th Ann. Rep. Ent. Soc. Ontario for 

 1887, Toronto, 1888, pp. 59-72 (Sess. Papers Ont. for 1888, 

 pt. 4, no. 21). Caulfield's list gives no Nova Scotian records. 



For general purposes our student will probably find Blatch- 

 ley's "Orthoptera of Indiana" (1903), and Walden's "Eux- 

 lexoptera and Orthoptera of Connecticut" (1911) the most 

 useful guides in the determination of species, etc. 



Life zones represented in Nova Scotia. — Two of the recog- 

 nized Life Zones are represented in this province, namely 

 (a) the Canadian Zone and (b) the Alleghaman division of 

 the Transition /jone. The former is the southern portion 

 of the Boreal Region, and the latter is the northeastern 

 transitional portion of the Austral Region. The Canadian 

 Zone, with its more northern fauna and flora, includes Cape 

 Breton Island (excepting doubtless the valleys of the Mar- 

 garee and Middle Rivers) and the Atlantic slope of Nova 

 Scotia proper, southeast of a line, of irregular course, roughly 

 drawn from near Antigonish to Grand Lake and thence tc 

 near Yarmouth. Lt may therefore be taken to approximately 

 comprise the greater part of Cape Breton Island, and the 

 Atlantic seaboard counties of Guysborough, Halifax, Lunen- 

 burg, Queens and Shelburne, and perhaps is most typically 

 represented from Halifax eastward. It is quite possible 

 that the highlands of northern Inverness and Victoria Coun- 

 ties, Cape Breton Island, may contain a fauna and flora 

 approaching somewhat more to that of the Hudsonian Zone; 

 and at any rate in that district will be met life of the most 

 northern type to be found in Nova Scotia. 



Westward and northwestward of the above-defined area 

 occurs a fauna and flora of a more southern tendency, 

 belonging to the Alleghanian or humid division of the Transi- 

 tion Zone. The Alleghanian division roughly includes such 

 sheltered valleys, apparently, as those of the Margaree and 

 Middle Rivers, in Inverness and Victoria Counties, (Cape 

 Breton Island), and all or most of the counties of Antigonish,
