Agricultural Experiment Station; Agriculture -- New York (State). 125 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. i&» 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- Fig. 16.—Stem of rasp- ' berry with eggs of O-Ceived the popular name of canthus niveus; c, ^g-The Snowy Tree-Cricket.

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 e
