254 THE CANADIAN ENTOMOLOGIST. 



The females are often found on the trunk and lower branches, and 

 are comparatively easily taken, but the males are usually higher up and 

 are quite difficult to obtain. 



Niveus is generally held responsible for a great deal of mischief done 

 to raspberry and blackberry canes by the females in laying their eggs. It 

 is my belief that most of this damage, at least in this locality, is caused 

 by the other two species of CEcanthus, which abound on raspberry bushes, 

 while niveus is seldom, if ever, found upon them. Niveus comes to 

 maturity about the first week in August and continues till late in October.

This is by far the commonest tree cricket in Ontario, and during 



August and September it abounds on shrubs and tall herbs, especially 



golden-rod, and is particularly plentiful on low grounds. Partially cleared 



bush lands supporting a rank growth of raspberry bushes, golden-rod, 



boneset and other tall herbaceous plants are favorite haunts. It is so 



common on rascberrv bushes that there is little doubt that the female is 



i. V 



responsible for much damage to the canes, though I have no proof of this 

 assumption. I have found it in cultivated raspberry bushes in gardens, 

 but it is more partial to wild districts. 



In shrilling the male elevates the tegmina to nearly a right angle with 

 the body and spreads them to an angle of about 45". The song is a 

 continuous and rather powerful trill, and is kept up all night and in 

 cloudy weather during the day when the sun is shining. It begins about 

 mid-afternoon.
