VI PREFACE. 



I 



The classification of Mr. Westwood, in the arrangement cf 1 

 orders and families, I have followed as closely as was possib 

 except in one or two instances: and where Insects have comnn 

 and familiar names, they have been given tt)gether with tin 

 scientific ones. 



To Dr. J. M. Toner, of Washington, for his suggestions ai 

 assistance in collecting material, I tender my thanks ; the san 

 also to N. Bushnell, Esq., and Hon. 0. H. Browning, of Quinc 

 111., for the use of their several libraries. 



I am much indebted, too, to Mrs. A. L. Ruter Dufour, 

 Washington, for many superstitions and two pieces of poet: 

 contained in this volume, I beg her to accept my thanks.
