The following paper on the Neuropteroid Insects of the Expedition, 

 by Nathan Banks, Division of Entomology, U. S. Department of 

 Agriculture, was originally published in the Proceedings of the 

 Washington Academy of Sciences, vol. u, pp. 465-476, Dec. 20, 

 1900. It is here reprinted from the same electrotype plates, so that it 

 may be quoted exactly as if it were the original. The original pagina- 

 tion has been preserved and transferred to the inner or hinge side of 

 the page, where it is enclosed in brackets, thus [466] ; while the con- 

 secutive 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 brackets], 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 head- 

 ing of the Academy's Proceedings and the original title, which was : 

 Papers from the Harriman Alaska Expedition, x. Entomolog- 

 ical Results (4): Netiropteroid Insects. No other alterations have 

 been made.
