than hind femora, straight, with the apex slightly enlarged and 

 rather blunt. 



This genus includes the small greenish white insects known as 

 tree crickets. These may be seen throughout the latter part of 

 the season clinging to tall weeds and shrubs, or on the trunks 

 and large branches of trees. The eggs of the tree crickets are 

 deposited in the tender shoots or pith of various plants. See 

 Fig. 60. Raspberries and blackberries are often seriously in- 

 jured by at least one species, whose punctures so weaken the 

 canes that they readily break off.
