NOKTH AMERICAN HYMENOPTEKA. 319 



Subfoniily Eurytomin^,. 



In " Entomologica Americana," vol. iv, 1888, p. 42, I gave a ge- 

 neric table of this subfamily, indicating many new genera, but with- 

 out designating types, as it was my intention to follow it shortly with 

 a descriptive paper, giving not only the full descriptions of the 

 genera, but a synopsis of our species. 



Several years have now passed and I am still at work on a syn- 

 opsis, but as this is still unfinished, it seems to me advisable to no 

 longer delay in indicating and describing the types of these genera, 

 and I here take the opportunity of doing so; also to indicate three 

 other genera at that time unknown to me, which I believe should be 

 placed in this group, viz. : Eudoxlnna Walker, placed by Walker 

 and Westwood with the Chalcidinie ; Chryseidu Spinola, placed by 

 Spinola with the Pteronialinre, and by Westwood with the Perilam- 

 pinoe; and Axbaa Walker, placed liy Walker and Kirby with the 

 Chalcidiua>, and by Cameron into a subfamily called Axiniinte. 



All of these genera are known to me in nature, and they are 

 placed here after careful study.
