Shade tree insects 



It is difficult to draw a sharp distinction betwen forms affecting forests and 

 those depredating on our shade trees. Some insects, hardly injurious in the 

 forests, are very destructive to shade trees and on that account it has been 

 deemed advisable to exhibit some of these species and their allies under one 

 head. Like that representing forest insects, the exhibit of shade tree pests 

 is very largely biologic and was represented by numbers 98 to 140, occupying 

 three horizontal trays and a nearly vertical one of the exhibit case.
