This is the only species of Orchelimuni that is distributed generally 

 over a large part of the Province. It becomes gradually scarcer to the 

 north of Lake Simcoe, and I believe it does not range much further north 

 than Muskoka. I found it sparingly at Dwight, but it did not appear in 

 Algonquin Park, nor did I take it at North Bay, although the proper sort 

 of environment, apart from the northern latitude, was often met with. 



This grasshopper is common in upland fields as well as low meadows, 

 and is fond of perching in clumps of tall grass. It reaches maturity 

 towards the end of July, and lasts until about the beginning of October. 



The song of the male is the familiar '■'■xr ,jip,jip, Jip, xr , 



etc," of which an interesting and detailed description is given by Dr. 

 Scudder in the Twenty-third Annual Report of the Entomological Society 

 of Ontario, 1893, p. 73. 



I have found great variation in the length of the tegmina and wings 

 in this species. Individuals with unusually long tegmina, and wings which 

 project some distance beyond them, are not uncommonly met with in the 

 north. I have taken them several times at Lake Simcoe and also at Lake 

 Muskoka, the Bruce Peninsula, and Walpole Id., River St. Clair. These 

 long-winged individuals resemble O. glaberrimum in appearance, but are 

 considerably smaller.

On September 14, 1899, I captured 3 males of this fine species from 

 the marshy shore of the " Rondeau," at Rondeau Provincial Park, Kent 

 Co. I took them while stridulating, their song being indistinguishable, as
