The following paper on the Odonata of the Expedition, by Rolla 

 P. Currie, Aid, Division of Insects, U. S. National Museum, was 

 originally published in the Proceedings of the Washington Academy 

 of Sciences, vol. in, pp. 217-223, July 13, 1901. It is here re- 

 printed 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 [218]; while the consecutive 

 pagination of the present volume has been added in the usual place. 

 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, xxn. 

 Entomological Results (14): The Odonata. No other alterations 

 have been made.
