Lesson 10 
BIBLIOGRAPHY 
Borers. 
The references in the following bibliography are selected as 
the best ones and those most easily secured. It is not complete but 
will helps you to know the different insects. A complete biblio- 
graphy would be confusing and require too much space as the 
references for some of the species would be greater than the total 
references given below. 
The two most comprehensive works on this important subject 
are Packard’s Fifth Rept., U. S. Entomological Commission, and 
Memoir 8, New York State Museum of Natural History, in two 
volumes, by E. P. Felt. These are both excellent works and you 
should have them. They are getting out of date in some cases in 
regard to means of control but they are the best we have at the 
present time, treating of the same number of shade tree insects. 
Packard’s Report is out of print and is hard to get. It is, however, 
the most comprehensive work treating of American forest and 
shade tree insects and contains liberal quotations from many of 
the early writings which are also out of print. 
Send for as many of these references as possible and use them 
when studying Lesson 10. Some of them also contain good des- 
criptions of other species to be considered in subsequent lessons.
