 col. 2 — 9 cm) 



Apple-tree aphis, Aphis mali Fabr., is identified, the remedy given and the state- 

 ment made that the species will probably not cause farther injury the present season.

Maples defoliated. (Country gentleman. June 23, 1898. (y^'- 491, col. 

 :3^—Z cm) 



Hundreds of silver maples were defoliated by a species of ?Nadata \^Xylina anten- 

 nata Walker] in Schenectady. The outbreak is probably due to a dearth of parasites 

 or favorable climatic conditions, and illustrates the destructive powers of many 

 insects if unchecked.
