The Keeweenaw Bay list corresponds closely to that of the Thunder 

 Bay District, Ont., the only species in the former not included in the latter 

 being the introduced Pe rip I a net a Americana and Tetrix Luggeri, whose 

 claim to specific rank is questionable. Only four species from the 

 Thunder Bay District are not reported from Keeweenaw Bay. The list 

 from the Porcupine Mountains and Isle Royale is also of a similar 

 character so far as it goes, but contains the additional species, Melatioplus 

 amplectens, Scudd.; Atlanticus pachymerus, Burm., and Ceuthophilus 

 sectusus, Scudd., all of which are Austral forms, whose occurrence in this 

 northern locality is somewhat surprising. 



In comparing the present list with that of Algonquin Park, we again 

 find a considerable correspondence, but in the latter locality there are a 

 number of Austral or Transitional forms, namely : Tettigidea parvipennis, 

 riarr.; ChortopJiaga vfridi/asciata, De Geer ; Spharagemon Bo//i, Scudd.; 

 Scudderia furcata, Brunn.; Orclielimum vulgar e, Harr.; Xiphidion 

 brevipenne, Scudd.; Nemobius pa/ustris, Blatchley, and CEcant/ius/asciatus, 

 Fitch. Of the several western types in the other lists mentioned, only 

 two were taken here, Melanophis Bruneri and Tetrix Brunneri, both of 

 which were quite local in occurrence. It may be mentioned, however, that 

 another of the western forms, Ckl<>ealtis abdominalis, has been recorded 

 from the Severn River, about 40 miles south-west of Algonquin Park. 



While the general characteristics of the Orthopterous fauna of 

 Northern Ontario are thus quite in accord with what we should naturally 

 expect, there are certain peculiarities worthy of special notice when we 

 come to consider the various localities separately. 



At Fort William the collecting was all done on the west side of the 

 Kaministiquia River. We crossed the river in a skiff and followed a road
