This species is fond of places where the grass grows thinly. I 

 obtained specimens at the Pas on the Saskatchewan River, and 

 at different points along Lake Winnipeg. I have also seen mu- 

 tilated specimens, doubtless of this species, from the Island of 

 Anticosti in the Gulf of St. Lawrence.
