VI INTRODUCTION. 



Transactions of the American Entomological Society (En- 

 tomological Section of the Academy), Volumes VI, 1877, to

 tion in 1875. 



Entomological News and Proceedings of the Entomological 

 Section of the Academy. I, 1890— XXIII, 1912. 



Because of the frequent change of generic names it has been con- 

 sidered essential to the usefulness of the Index to provide alpha- 

 betical references to the specific designations. In the compilation 

 questions of synonymy have not been considered. Except where 

 errors are manifestly typographical, no attempt has been made to 

 correct the orthography of authors.
