328 THE CANADIAN ENTOMOLOGIST. 



The mature Katydids appear about the third week in July, and 

 remain until about the first of October. 



This species is usually taken for Amblycorypha oblongifolia by 

 amateur collectors, and I have little doubt it was, at least in part, the 

 species referred to under that name by Caulfield in his " Sketch of 

 Canadian Orthoptera" (Ann. Rep. Ent. Soc. Out., 1887).

 tegmina, $ $ 28.5 mm.; of ovipositor, 7 mm.; width of tegmina, $ 6

This species seems to be quite generally distributed throughout 

 Ontario, as fiir north as Lake Nipissing, but is commoner in the southern 

 part. It frequents trees and bushes about the edges of woods and 

 thickets on both dry and marshy ground, but most often on the latter. 

 The earliest date upon which I have taken the imago is Aug. 7, at Point 

 Pelee, but it may appear somewhat earlier. It remains until about the 

 end of September. 



The song o{ S. furcata is very like that o{ pistillata. Riley says: 

 "The shrill of the male is by no means so loud as that of the oblong- 

 winged katydid. Amblycorypha oblongifolia, De Geer, in which its sound 

 is always drowned in the woods. It consists of a softer zeep, zeep, some- 

 times uttered singly, but generally thrice in succession. The call is 

 occasionally responded to by a faint chirp from the females, produced by 

 the stretching out of their wuigs as for flight, and is as often heard in the 

 day as at night."
