l8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.84 



Another entomologist who was to become famous began to pub- 

 lish on economic entomology at al)Out this same period. Mr. S. H. 

 Scudder published some notes on white ants in the Proceedings of 

 the Boston Society of Natural History in June, i860; and the fol- 

 lowing year, in the same Proceedings, published an account of a 

 destructive aphis and the army worm. Although as boys Packard 

 lived at Orono, Maine, and Scudder at Boston, they began to cor- 

 respond before college days on the subject of entomology. Later 

 they came together at the Agassiz Museum, and each followed a 

 career of distinction, ultimately achieving very high reputations and 

 receiving many foreign honors. Scudder did not concern himself so 

 much with economic entomology as did Packard. Nevertheless, he 

 pulMished more than a dozen articles of more or less importance and 

 of an economic character. He was the first man to make a compre- 

 hensive study of the progress of an injurious species introduced from 

 Europe. His paper, entitled '* The Introduction and Spread of Picns 

 rapae' in North America, 1860-1886," was published in the Memoirs 

 of the Boston Society of Natural History, Volume 4, 1887. As the 

 result of this study, we understand the spread of this injurious insect 

 at that early date quite as well as we understand now the spread of 

 those much later immigrants, the cotton boll weevil, the gipsy moth, the 

 San Jose scale, the alfalfa weevil, and the European corn borer. 



All through his life Scudder was most helpful to the economic 

 entomologists who were coming up. He was versed in the literature 

 of entomology ; he was an authority upon the diurnal Lepidoptera 

 and upon the Orthoptera, and was of the greatest help to many of us. 

 He was a delightful, scholarly man personally, and a charming 

 writer. In addition to the two fields mentioned, he did much work 

 with fossil insects and published elaborate and well illustrated papers 

 in this field. 



This reminds me of an anecdote : When Filippo Silvestri first 

 visited this country (in 1908) he had done much work on fossil 

 Myriapods, and one day while at Boston he was asked by W. F. 

 Fiske and, I think, A. F. Burgess if he would like to see Scudder's 

 types of fossil Myriapoda. They took him to Cambridge, and, with 

 Scudder's permission (the latter was lying paralyzed at that time), 

 showed him the type specimens. He examined them and made no 

 comment, until finally Fiske said, "What do you think of them?" 

 The story is that he replied, " I sink zay are all caturplars." It was 

 some time before Fiske figured out that he meant caterpillars. 



' Now the common cabbage butterfly.
