INSECTS OF MINOR IMPORTANCE AFFECTING FOREST 



TREES 

 This divie'on is purel\" an arbitrar)' one and made as a matter of con- 

 venience because it enables tlie bringing together of accounts relating to 

 species which are more or less injurious from year to year. Many of the 

 insects noticed in this latter section, are of considerable importance and 

 occasionally may cause serious injury. This division is defective in that it 

 involves looking in several places in order to learn about tlie insects 

 affecting a tree, and this difficulty is remedied in part by indexing all the 

 species under their food plants as well as under their generic and specific 

 names.
