 confess that 1 like sometimes to see the dry light of science diver-

ACKNOWLEDGMENTS. As already noted, this work is Itavil 

 largely upon my former one "The Orthoptera of Indiana." In 

 the preparation of that, as well as in my earlier studies of the 

 group, I was greatly aided by two men to whom T wish to first 

 pay tribute. One was Samuel H. Scudder of Cambridge. Mass. 

 a man noted for his varied accomplishments a devoted student 

 of insects, especially of butterflies and Orthoptera. He was the 

 father of American Orthopterology, and lo him more than to all 

 his predecessors and contemporaries combined is due our present 

 knowledge and classification of the group. When, in 1801, he 

 \vrote his first paper on Orthoptera fewer than 00 species were 

 recognized from North America and a number of those were 

 synonyms. In 10011, \vhen he issued his second Catalogue sr(; spe- 

 cies were included. .'JS."> of which had been described by him. A 

 number of these have since been shown to be synonyms, for his 

 later work, especially on (''('tttJtojtliiJux and M<-]<ni<>nlin<, was hur- 

 ried and many mistakes naturally resulted. Of his published 

 irers on Orlhoptera no fewer than S1 are included in the 

 bibliography accompanying 1his work, while a large number of 

 others dealing with exlra-limital srecies are not mentioned. Al- 

 ways willing to answer questions and ever interested in any new 

 form which was discovered, his counsel \vas to me for many years 

 both helpful and inspiring. TTis collection of Orthoptera with its 

 many types is now in the Cambridge Museum of Comparative 

 /oology, where it is one of the lodestars which attract to that 

 Mecca of entomologists those interested in Orthoptera from all 

 parts of the world. 



Another who aided in solving many a knotty problem in m\ 

 old tyro days was Lawrence Brunei-, then as now the Professor of 

 Entomology in (he University of Nebraska. He has long been 

 interested not only in the Orthoptera of this counti'Y but in those 

 of South America, and has published many papers and described 

 many of the species belonging to our fauna. His cabinet of 

 North American forms with its numerous types is now a part of 

 the Philadelphia collections. 



When T began the preparation of this work T realized that T 

 would have to call many times ui on the i resent-day special stu- 

 dents of North American Orthoptera, those who have kept the
