The attention of the fruit grower is usually first called to this 

 injury by the death of the infested cane. It is observed that some 

 canes fail to put forth any leaves in the spring. An examination 

 of such canes reveals as the cause of their death the presence of 

 a lono: ragged ed^ed wound of the form indicated at a in Fig. 16.

Frequently the cane will be split open at this 

 place. If the rough surface of the wound be 

 cut away with a knife, the injur}' will be 

 found to consist of a longitudinal series of 

 punctures placed close together. By split- 

 ting the cane the nature of the injur} 7- can 

 be seen even better. Such a section is rep- 

 resented at b in the figure. The punctures 

 extend through the woody part of the cane 

 into the pith, and here there is in each an 

 oblong, cylindrical egg. One of these eggs 

 is represented enlarged at c. 

 The insect which thus se- 

 riously injures the raspber- 

 ry canes in preparing a safe 

 receptacle for its eggs is a 

 delicate greenish - white 

 cricket. On account of its 

 color and of its habit of liv- 

 ing among the foliage of 



. trees and shrubs, it has re-

Oecanthus niveus. Fig. 17 represents the male of this species. Its 

 wing-covers are broad and transparent so that the folded wings can 

 be seen through them. The wing-covers are crossed by oblique 

 thickenings or ribs, which form a part of the musical apparatus 

 of this insect. The female differs somewhat in appearance from 

 the fact that the wing-covers are closely wrapped about the body, 

 making the insect much narrower than her mate. 



The chirp of this cricket is a very familiar sound in most parts 

 of our state during the latter part of summer and early autumn. 

 It is a monotonous repetition of a cry, which with a little effort on 

 the part of the listener, can be made to sound like h'afv-did, Katy-
