Severn River, Aug. 12, 1898; Dwight, Muskoka, Aug. 10, 1903 ; North 

 Bay, Sept. 12, 1900. 



I have also taken this species at Agassiz, B. C, where it was common 

 on Sept. 9, 1897.

This fine large katydid is confined to the southern part of the 

 Province, where it is common. I have seen one specimen taken at 

 Toronto, but it must be very rare there. It is coirjmon from Hamilton 

 westward along Lake Erie to the St. Clair River. 



I found it common on shrubs and tall herbs on the borders of an 

 open marsh at Arner, Essex Co. The marsh was bordered by low hills, 

 thickly covered with hardwood. At Point Pelee immature examples were 

 plentiful upon weeds in openings in a low wood, and on the Niagara 

 River, near the Glen, I found it in numbers on tall weeds and grass in a 

 pasture near a small wood. Blatchley says: " Oblongifolia frequents the 

 shrubbery and flowers of the golden-rod and other CompositiB along fence 

 rows and the edges of thickets and woods, especially in damp localities." 

 (Orth. Ind.,p. 351.) 



The specimens taken on the Niagara River were found by tracing the 

 note of the male to its source. In this way I observed the insect in the 

 act of stridulating. The note is very harsh and scraping in character, and 

 is usually of about three-fifihs of a second's duration. At a little distance 

 it sounds something like " kizizik !" I have heard it at night and in the 

 afternoon while the sun was still shining. 



In Caulfield's " Preliminary List of the Orthoptera of Canada " (Ann. 

 Rep. Ent. Soc. of Ont., 1887, 70) this species is reported as being com- 

 mon at Ottawa and Toronto, and as being found in Ontario generally 

 to north of Lake Superior. This is without doubt an error, the reference 

 being to another species, probably Scudderia pistillata, which I have
