 in June and July, and cut them off and burn them. 



Ifo. 14. — The Imbricated Snout-beetle. 



Epiccerus imbricatus (Say). 



This is a small snout-beetle or weevil, which is common in 

 some localities on apple and cherry trees and injures them 

 by gnawing the twigs and

 and Kansas. \ 



It is a very variable beetle ; 

 usually it is of a silvery-

but sometimes these latter are wholly or partly wanting. 

 Nothing is as yet known of its history in the earlier stages of 

 its existence.

 cite alarm, they could probably be collected by jarring the 

 trees, as in the case of the plum-weevil, and then destroyed. 



No. 15.— The Seventeen-year Locust. 



Cicada septendecim Linn. 



The seventeen-year locust is an insect very well known 

 throughout the United States, and is sometimes met with in 

 Canada. As its name implies, it generally requires seventeen 

 years in which to complete its transformations, nearly the 

 whole of this period being spent under ground. 



The perfect insect measures, when its wings are expanded, 

 from two and a half to three inches across. It is represented 

 at c in Fig. 24. The body is stout and blackish, the wings
