'direction, and has j^enerously turned over to me all his notes on transfonnatioiis, geographical 
distribution, etc., his contributions very much enhancing the value of this work. . 
I am also indebted to the authorities of the American Museum of Natnralllistory, New York, 
for the opportunity of examining the types of the late Mr. IJemy Edwards, and a few types of 
Mr, Grote. Other material and types in the Museum of Comparative Zoology at Cambridge, 
Mass., of the Boston Society of Natural History, particularly the Harris collection, and the 
collection of the American Entomological Society at Philadelphia, have been examined, and to 
the authorities in charge I am specially indebted. I should also acknowledge the frequent aid 
rendered by Mr. Henry Edwards before his death, and the labors of those who have in former 
years done much pioneer work in collecting and describing the Boinbyces, especially of my friend, 
Mr. Aug. E. Grote, now of Bremen, Germany. 
Mrs. Annie Trumbull Slosson, of New Y"ork, has-generously given me valuable material, and 
given me free access to her collection, and in this and other ways laid me under special obligations. 
Mr. H. G. Dyar and Mr. B. Neumogeu have freely shown me their imi)ortant collections, 
and generously loaned specimens for illustration and study. Mr. Dyar has in a number of ways 
rendered most efficient aid, and has my hearty thanks. We have together made a number of 
'Comparisons, and thus arrived at results which otherwise would have been less certain. 
Dr. J. A. Lintner, State Entomologist of New York, has opened his collection to me, and loaned 
me several colored drawings of larvie. 
From Eev. E. D. Hulst, of Brooklyn, I have received by exchange many specimens. 
Dr. E. Thaxter has permitted me to examine his very valuable collection of larvre, now in 
the Cambridge Museum, and Professor French, of Carboiidale, 111., has also kindly heli)ed me. I 
am much indebted to Miss Emily L. Morton, of Newburg, N. Y., for eggs, larva*, and the use of 
several colored drawings of Dataiia larvm, etc., and for notes on their habits. To Miss Caroline 
E. Soule also I am under obligations for a line colored sketch of Nerice hifleniata-. 
I am also indebted to the following entomologists who have aided me with larva*, eggs, moths, 
local lists, etc.: Mr. O. S. Westcott, Chicago, 111.; iMr, Tallant, Columbus, Ohio; Mr. Graef, 
Brooklyn, N. Y.; Mr. Trevor Kincaid, Olympia, Wash.; Mrs. Feruald, Amherst, Mass.; Mr. 
Charles Palm, of New York; Mr. William Beutenmueller, in charge of the collection of insects 
in the American Museum of Natural History, New York, and to others whose aid is acknowledged 
in the course of the work. 
To Mr. Joseph Bridgham, who has made the drawings of the larval stages, I am under special 
■obligations. Besides the work of drawing, lie has secured many of the larvie, and sliown the 
utmost pleasure iu aiding me to the extent of his ability. It is to be hoped that the work of the 
lithographer will bring out the delicacy of color and fidelity in drawing of the artist. 
I have also had ten drawings of WalkePs tyjies iu the British Museum, made by Mr. H. 
Knight, of London, with the permission of Dr. A. Guenther, suiierinteudcut of the zoological 
department, to whom my hearty thinks are due; also for his courtesy iu allowing me, with the 
kind aid of Mr. A, G. Butler, assistant in entomology, to examine some of Walker's types. 
I have also had copied iu the plates a number of excellent colored drawings of caterpillars, 
made by the late Maj. John Eatton Le Conte, which were loaned me for such a juirpose by his son, 
Dr. John Lawrence Le Conte, a few years before his death. They were made iu Georgia, presuma- 
bly at Sans Souci, on the Ogeechee Elver, about 16 miles south of Savannah.^
