There are also several collections of which I know little or nothing 

 and of which I therefore avoid all specific mention. 



Prof G. H. French has probably a very good collection and a num- 

 ber of his own types. 



These two orders, Coleoptera and Lepidoptera, attract most of our 

 collectors, and there are plenty of good though not very large collections 

 all over the country — among the better known are those of Dr. Castle, of 

 Philadelphia, Coleoptera ; Mr. Schoenborn, Washington, Lepidoptera ; 

 Mr. Noble, Savannah, Coleoptera ; Mr. Schuster, St. Louis, Coleoptera : 

 Mr. Goodhue, Webster, N. H., Lepidoptera; Prof Snow, of Lawrence. 

 Kansas, whose collection of Coleoptera and Lepidoptera deserves a better 

 description than I am unfortunately able to give ; Messrs. Reinecke and 

 Zesch, Buffalo, N. Y. , Coleoptera; and the Pacific Coast collectors 

 Messrs, Koebele, Coquillet, Ricksecker, Wright, Rivers, Behr, Behrens, 

 and perhaps some others. 



In Hemiptera, the collection of Prof P. R. Uhler, of Baltimore, 

 Md. , stands pre-eminent. Prof Uhler has been for many years gathering 

 material, and studying and arranging it for study. From him, directly or 

 indirectly, most of our named material comes. 



I\Ir. Ashmead, of Jacksonville, Fla. , has more recently begun the 

 study of this order, and, as I understand, has accumulated a very large 

 material. 



Prof Osborn, of Ames, Iowa, has quite a collection uf Hemipiera, 

 and has devoted considerable time to their study. His favorites are Mal- 

 lophaga and Pediculidce, the exact location of which is perhaps still 

 matter of dispute. 



The collection of Mr. Heidemann of Washington, D. C. , is a rapidly 

 growing though somewhat local one. Mr. Heidemann, by careful col- 

 lecting has accumulated a large amount of material, much of it unde- 

 scribed. 



In this order there is a wide and interesting field for the student, the 

 Homoptera affording some of the most intricate and fascinating problems 

 ever confronting a Biologist. 



In the Thripidce, assuming them for the present to be undoubted 

 Hemiptera, the collection of Mr. Pergande of Washington is unique. 

 There are about half a dozen species described, and Mr. Pergande has in 

 his collection distinguished nearly 150 species!! Mr. Pergande is not 

 troubled with the mihi itch — yet. 



In Orthoptera, Mr. Scudder's collection stands first. So I am as- 

 sured by Prof Riley and Mr. Bruner, both of whom have seen or studied 

 it. I have not had the good fortune to see it myself 



Mr. Bruner's collection, at West Point, Nebraska, stands next in
