did. This cry is begun early in the evening and is contiuued un- 

 remittingly till late in the night ; all of the males in one region 

 chirping in unison. The chirp of this cricket is very different 

 from that of the true Katy-did, being less rasping and much more 

 monotonous. I have never heard the Katy-did at Ithaca ; but I 

 know it to be common in certain parts of this state. In those sec- 

 tions in this part of the country where the Katy-did does not 

 occur, the chirp of the snowy tree-cricket is the most prominent of 

 all sounds made in the night by insects. 



Except for the injury caused by the female in ovipositing, the 

 snowy tree-cricket is not regarded as a noxious insect. Its diet is 

 said to consist in part at least of plant lice and other small insects. 

 It is also said to feed later in the season on ripe fruits ; but I have 

 never heard of its being seriously injurious in this way. 



This cricket lays its eggs in the canes late in the summer or in 

 the autumn. But they do not hatch till the early part of the fol- 

 lowing summer. It is therefore a simple matter to cut out the 

 infested canes in the spring after the other canes have put forth 

 their leaves, but before the eggs have hatched, and by burning 

 these canes to check the increase of the insect. 



Although this insect oviposits by preference in the canes of 



black raspberry, its eggs are found in various other shrubs and 



even in the twigs of trees.
