The following report on the Sphegoidea and Vespoidea of the Ex- 

 pedition, by Prof. Trevor Kincaid, was originally published in the 

 Proceedings of the Washington Academy of Sciences, vol. n, pp. 507 

 510, 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 pagination has been preserved and transferred to the inner or 

 hinge side of the page, where it is enclosed in brackets, thus [508] ; 

 while the consecutive pagination of the present volume has been added 

 in the usual place. The present headpiece and title have been substi- 

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

 original title, which was : Papers from the Harriman Alaska Ex- 

 pedition, xiv. Entomological Results (8): The Sphegoidea and 

 Vespoidea. No other alterations have been made. The generic name 

 ' Arachnospila ' on page in [509], ninth line from top, should read 

 Arachnophila .
