distribution. Between 1880 and 1890 his energies were devoted 

 chiefly to other groups and subjects — fossil insects, and the prepa- 

 ration and pubhcation of his great work on butterflies — but for 

 the ten years from 1891 to 1901 his orthopterological activity 

 was incessant, resulting in nearly 70 titles in the order, including 

 months of work on the "Revision of the Melanopli," and termi- 

 nating practically with the preparation, jointly with Professor 

 Cockerell, of the "First list of the orthoptera of New Mexico." 

 Would that his strength might have been as were his days, that 

 he might have been spared the afflictions of his later years: how 

 much more he would have given us ! 



It would be superfluous to name here even the more important 

 of his systematic papers — every student of the order in America 

 is acquainted with them perforce and a full bibliography up to 

 the end of 1900 will be found in his "Index to North American 

 orthoptera" (Occas. papers Boston Soc. Nat. Hist., Vol. 6, 1901) 

 which is practically a bringing-up to the end of the century of 

 his "Catalogue" of 1868. Mention should be made in this con- 

 nection, however, of his "Catalogue of the described Orthoptera 

 of the United States and Canada" (Proc. Davenport Acad. Nat. 

 Sci., Vol. 18, 1900) which is a list of the species described up to 

 that time; also to the scholarly "Revision of the Orthopteran 

 group Melanopli," a work already alluded to, which involved a 

 prodigious amount of labor and brought something like order out 

 of the chaos which prevailed at the time in reference to this domi- 

 nant group of North American Orthoptera; and also to the 

 "Guide to the genera and classification of North American Orthop- 

 tera," a most useful aid to the student of the order. 



His studies were not confined solely to the North American 

 members of the order but extended to those of all parts of the 

 world. One hundred and twenty-two foreign species were described 

 by him in his earlier period of activity ("List of exotic Orthoptera 

 described by S. H. Scudder, 1868-1879," etc., — Proc. Boston 

 Soc. Nat. Hist., Vol. 27, pp. 201-218) and in later years the orthop- 

 tera of the Galapagos Islands and the Melanopli of the Old World 

 and of South America received his attention. 



Mr. Scudder did relatively little field work and that chiefly 

 in his earlier years; but that he was equally at home in the field 

 as in the laboratory is fully attested by his notes on the distribu-
