ILLUSTRATIONS. 



The illustrations in this edition are nearly all identical with 

 those used in the edition of 1900, and there acknowledged in 

 detail. A very few have been omitted and substituted by better 

 figures obtained from the United States Department of Agricul- 

 ture, Division of Entomology. A very few have been drawn for 

 this work by Mr. John A. Grossbeck, and these in general bear 

 his initials.
