Preface 
a partial return to the learned author for the money, labor, and 
time expended upon it. The present volume, while not pretend¬ 
ing to vie in any respect with the magnificence of the illustrations 
contained in these beautiful and costly works, nevertheless pre¬ 
sents in recognizable form almost every species figured in them, 
and in addition a multitude of others, many of which have 
never before been delineated. So far as possible I have em¬ 
ployed, in making the illustrations, the original types from which 
the author of the species drew his descriptions. This fact will no 
doubt add greatly to the value of the work, as it will not only 
serve as a popular guide, but have utility also for the scientific 
student. 
I am under obligations to numerous friends and correspondents 
who have aided me, and take the present opportunity to extend 
to them ail my hearty thanks for the generous manner in which 
they have assisted me in my pleasant task. I should fail, how¬ 
ever, to follow the instincts of a grateful heart did I not render an 
especial acknowledgment to Mr. W. H. Edwards, of Coalburg, 
West Virginia, and Dr. Samuel H. Scudder, of Cambridge, Massa¬ 
chusetts. Justly esteemed as the two foremost lepidopterists of 
America, it is my honor to claim them as personal friends, whose 
kindness has much aided me in this labor of scientific love which 
l have undertaken. For the kind permission given me by Dr. 
Scudder to use various illustrations contained in the “Butterflies 
of New England ” and other works, I am profoundly grateful. 
I am under obligations to Messrs. Charles Scribner’s Sons for 
permission to use the cuts numbered 46-49, 51-56, 59, 61, 62, 
and 73, which are taken from the work entitled “Taxidermy and 
Zoological Collecting,” by W. T. Hornaday, and to the authorities 
of the United States National Museum and the heirs ot the late 
Professor C. V. Riley for other illustrations. 
Should this book find the favor which I have reason to think it 
deserves, I shall endeavor shortly to follow it by the preparation 
of a similar work upon the moths of the United States and Canada.
