McDunnough's holandanwn is a straight synonym. It was distin- 

 guished by the thicloiess of the subapical bar of fore wing and its 

 relative nearness to apex, characters that are extremely variable 

 and not to be relied upon. There are no genitalia differences be- 

 tween it and typical olivaceanum. 



Genitalia figured from specimens in National Collection from 

 Buffalo, New York (William Wild, " VII-15-09," male) and Ottawa, 

 Canada (C. H. Young, " 28-VI-1905," female). Bursa of female 

 without signum.
