I have ocrasion also to a«-know|r«|«re a further indebtedness to Mr. II m- 

 DfMvN of f'idunibia ( Penn<^ylvani:i), who enjoys a Kur<i|x'an reputation as a 

 naturalist, for several valuable notes on various insects ; an<l eouKI bis n.s- 

 sistan«"e have been still farther pro< iired, the value of my work would un- 

 doubtedly have In-en ;;reatly enhanced. 



1 have fi<jured su«'h insects ,ns 1 have .seen, and know to Im-Iou^ to New- 

 York an«l N'ew-Kn'il.-Hul ; but I have not seen thi-ni in all their states, an«l 

 am th«-n-fore frecpjently indebte<l to others for the lifjures given of the larva 

 and pupa sta<?es. Some are copied from Aiaiorr & Smith's work on the in- 

 sects of (Ie()rj;ia, and some from other works of like kin<l. I have fi;jnred 

 very few foreij^n sjK'cics, and these h.-jve had sf»nie s|HM'ial puqK>.se in view. 



Tin- figures have been drawn from s|M'cimens of the insects themselves, 

 by E. Kmmons junior, and are faithful and accurate |M.rtraits of the indivi- 

 duals frcau whiih they were taken. It is tlillicult, however, to .M'cure a 

 finished an«l imiform coloring, esj»ecially for so large an c<lilion as three 

 thou.sand c(»pies. 



I do not deem it nec^'ssa^^• to point out the limits of this volume; for the 

 keiMi-sighted, :ind those who are disp«>sed to look alter them, will Itnd them 

 with little trouble. I am persuadeil, however, that the gcner.d reader, ns 

 well as the student, will lind in it many valuable rcronls. E. EMMONS.
