THE CANADIAN ENTOMOLOGIST. 327 



chiefly of white and red pine, oak and sassafras, wliile the open grassy 

 places are largely grown up with New Jersey tea (Ceanothus Americana), 

 sweet-fern, great quantities of lupine, bush-clover, Desmodium, and many 

 kinds of Compositfe. The two larger specimens from the Severn were 

 taken under very similar conditions, but the other three came from an open 

 bog, forming a small lake which had become filled in and was covered 

 with a thick tangle of the dwarf Cassandra ( ChamcedapJme calyculata). 



The day note of this katydid has been represented by Scudder by 

 the syllable " bzrwi." The only song that I have heard was produced 

 during the afternoon, and is composed of a ratlier harsh note lasting about 

 one-third of a second, and repeated three or sometimes four times in 

 succession. Each note ends quite abruptly before the next is produced. 

 The night song is described by Scudder as consisting of a "repetition 

 ordinarily eight times, of a note which sounds like tchw. It is repeated at 

 the rate of five times in three-quarters of a second, making each note half 

 the length of the day note."

This is a northern species, much the most abundant in northern 

 Ontario, but I liave not taken it south of Toronto. It is common on 

 bushes, tall herbs and grass on the borders of low woods and along fence 

 rows. 



Its note is less harsh than that oi ciirvicatida. The night song some- 

 what resembles " zeep, zeep" repeated about five or six' times at the 

 rate of about twenty-three times in five seconds. Late in the afternoon, 

 while the sun is still shining brightly, this night song is begun, but at this 

 time it is more rapid, the notes being produced at the rate of about five 

 per second, and repeated seven or eight times. The true day song consists 

 of a single note lasting about three-quarters of a second, somewhat like 

 " kzrrt !"
