three-fourths of an inch long, and by burrowing in the wood fre- 

 quently girdles the canes. The perfect beetles emerge about 

 the time that the plants are in full blossom. 



Remedies. — As the insects winter over in the canes, they 

 may be destroyed by cutting and burning all the infested wood 

 some time during the winter. 



Snowy Tree Cricket (Oecanthus niveusj, — This insect does 

 not feed on the raspberry plant in any way but it is injurious 

 on account of its peculiar habit of puncturing the canes with 



lines of little holes in which 

 it deposits eggs. If this work 

 does not kill the canes, it so 

 weakens them that when they 

 start in the spring they are 

 very apt to break off as soon 

 as the foliage is expanded. 

 The eggs, which are laid in 

 autumn, are yellow and about 

 one-eighth of an inch long. 

 They are not readily seen 

 when laid, but by the latter 

 part of winter the infested 

 canes take on an unhealthy 

 appearance by which they 

 may be readily located. This 

 insect feeds upon leaf lice and 



is thus beneficial to some ex-

Remedy.— The only remedy is to cut out and burn the in-
