There is an authentic male of osmundana from Maine in the 

 Cornell collection labeled by Fernald. It agrees in pattern and 

 genitalia with Kearfott's ochromediana. I can not find any of 

 the differences that Kearfott uses to separate his supposed species. 



Male and female genitalia figured from specimens in National Col- 

 lection from Hampton, N. H. (male, S. A. Shaw, " VIII-14-1907 ") 

 and Samons, Mass. (female, reared by W. O. Ellis from Osmunda 

 cinnamoinea.^ 28 May, 1921). 



Bursa of female without signum. 



There is a male in the National Collection reared from larvae 

 feeding on Pteridium aquilinum (" 7-7-16," Witesbog, N. J., Quani- 

 tance no. 12743, H. H. Scammell, collector). Kearfott also records 

 (Ins. New Jersey, 1910, p. 540) seeds of Ambrosia trifida as a food 

 plant.
