Fletcher in the Report of the Geological and Natural Historj' 

 Survey of Canada for 1887-88.^ If any Coleoptera were 

 taken the}' are not included in the enumeration of insects. 



To students wishing to see material from the region treated 

 of, the following list of cabinets wherein more or less complete 

 sets of them have been placed bv the writer mavbe of interest. 

 First in importance is the series conlained in the National 

 jMuseutn, complete or nearly so, in all orders but the Coleop- 

 tera; that of Dr. Geo. H. Horn in Philadephia for Coleoptera; 

 several of the larger New York collections and the Museum 

 of the Geological and Natural History Survey of Canada 

 also contain considerable series in this order, while a set, com- 

 plete except about half a dozen species, has been retained in 

 the cabinet of the writer, now deposited in the ^Museum of the 

 State University of Iowa. 



To many friends, the writer is under obligation for aid in 

 correctly identifying the material brought back and for valua- 

 ble notes on distribution. Dr. Horn has kindly gone over a 

 very large part of the collection and Capt. Thos. L. Casey 

 has named the material in some groups of Staphylinidge to 

 which he has given special attention. To Dr. John Hamilton, 

 thanks are due both for determinations and notes, while 

 Messrs. Leng and Brendel have helped on the Cerambycida^ 

 and Pselaphid33. For an examination of the Aleocharini and 

 some other Staphylinidis I am indebted to the distinguished 

 European writer, M. A. Fauvel, of Caen, France. Dr. Sel- 

 wyn has very kindly sent me the Reports of the Survey of 

 which he is Director and they have proved valuable in the 

 preparation of this paper.

 data.
