This seems to be a common species. It may be known by its large 

 size, the peculiar color, like old unpainted oak-wood, with light slashes, and a 

 distinct marginal line. I confess I mistook it for a Chesias. On sending a 

 specimen to M. Guenee, he informs me that it is his E. subapicata. Professor 

 Zeller has also determined it to be that species from specimens I sent him

This is the largest species of the genus, and may be recognized by its 

 large size, the chalky-white color, and the heavy, dark, conspicuous costal 

 spots. It is allied in structure and venation to E. zygadeniata, but differs in 

 the much shorter palpi. 



The Californiari specimens have longer, more acute fore wings than those 

 from New Hampshire.
