In pattern much like footianum; but of quite a different color. 

 The characters given in the key will readily separate the two species. 



Fernald 's cotype.s represent a mixed series. The Canadian sp ci- 

 mens correspond to what we have always identified as atrodentanum, 

 while the Texas specimens represent a new species which is described 

 in this paper (p. 160) as exaeresimum. I am therefore restricting 

 the name to the form with blackish shading on costal half of median 

 band, and designating one of the cotypes from Ontario as the 

 holotype. 



Male (harpe) and female genitalia figured from specimens in 

 National Collection from New Brighton, Pennsylvania (H. D. Mer- 

 rick, " VII-28-06 " and " VIII-9-07 ").
