ON THE ORTHOPTERA OF NORTHERN ONTARIO. 



BY E. M. WALKER, TORONTO. 



The few published records in Orthoptera from Northern Ontario are 

 based on odd captures made by a number of collectors in various locali- 

 ties, no local lists having been published from any point north of 

 Algonquin Park, where the writer collected in 1902 and 1903, and listed 

 the species taken there in the 36th Ann. Rep. Ent. Soc. Ont. (1905). As 

 Algonquin Park lies at the extreme southern limit of the Canadian Zone, 

 its biota containing many Austral elements, we have still only a very 

 fragmentary knowledge of the Orthopterous fauna of the strictly Boreal 

 parts of the Province. 



Since the Algonquin Park list appeared, the writer has collected 

 Orthoptera in three localities in Northern Ontario, all situated well within 

 the limits of the Canadian Zone. These are Fort William and Nipigon, 

 Thunder Bay District, and the Temagami Forest Reserve, Nipissing 

 District. Only a few days at the end of August, 1907, were spent at Fort 

 William and Nipigon, and this brief time was occupied chiefly in collecting 

 the species of the Odonate genus Aeshna ; nevertheless, it is believed that 

 nearly all the species of Orthoptera resident there were taken, though none 

 in large series. In the Temagami District a fortnight's canoe-trip was 

 made in the first half of September, 1908, and good opportunities for 

 collecting were afforded. 



To make the list as complete as possible the names have been added 

 of a few other species previously known from Northern Ontario, which 

 were not taken at the localities mentioned. A few others, not included in 

 the list, have been taken at North Bay, Lake Nipissing, but probably do 

 not range much further north, and are, perhaps, better excluded from the 

 fauna of the Canadian Zone. 



The combined result of these various records is, on the whole, what 

 one would expect, judging from our knowledge of the Orthoptera of 

 Northern Michigan as embodied in the following papers :
