VI PREFACE. 



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

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

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

 and familiar names, they have been given together with their 

 scientific ones. 



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

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

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

 111., for the use of their several libraries. 



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

 Washington, for many superstitions and two pieces of poetry 

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



Greensburg, Pexxa., 

 July 10th, 1865.
