The following paper on the Apterygota of Alaska, by Justus Wat- 

 son Folsom, of the University of Illinois, was originally published in 

 the Proceedings of the Washington Academy of Sciences, vol. iv, 

 pp. 87-116, March 27, 1902. It is here reprinted from the same 

 electrotype plates, so that it may be quoted exactly as if it were the 

 original. The original pagination has been preserved and transferred 

 to the inner or hinge side of the page, where it is enclosed in brackets, 

 thus [88] ; while the consecutive pagination of the present volume has 

 been added in the usual place. In the plates the original numbers and 

 running headline (slightly abbreviated) have been preserved [in brack- 

 ets] , while the volume designation and serial plate numbers have been 

 added in the usual place. The original text references to the plates 

 are unchanged. The present headpiece and title have been substituted 

 for the running heading of the Academy's Proceedings and the original 

 title, which was : Papers from the Harriman Alaska Expedition, 

 xxvn. Apterygota. No other alterations have been made.
