spread down Franklin to Second Street. 



When first ob- 

 served, a small 

 amount of labor 

 would have exter- 

 minated them, but 

 owing to negli- 

 gence, the trees 

 which form the

 said locality, pre- 

 sent during the 

 summer a disgust-

 general habits of 

 the insect are as 

 follows : 



In the early 



substance surrounding the insect at b. Spring the female 



is found on the bark apparently torpid. As warm weather 

 advances the body is more swelled, and carefully raising it 

 with a knife, numerous oblong eggs will be found, the

 young are hatched, and make their escape from the 

 lower end, where it is either slightly elevated or notched. 

 They then wander with considerable activity over leaf 

 and branch, inserting their beaks into the bark or 

 leaves, drawing up the sap, which nourishes them.

 insects belonging to the Coccidce. 



While the Lecanium acericola continue their exhausting
