E. perangulatn n. sp. — Expands 38-42 mm. In many respects like E. 

 venata Grt., and probably its representative in Colorado. The ground color is 

 much darker, being dark gray instead of whitish, and the space between the

 there is the same row of black points on the hind wings, though fainter and 

 "sometimes obsolete in E. perangnlufa ; both fore and hind wings are narrower 

 than in E. venata, and the insects has considerably the appearance of Nepytia 

 semiclasaria Walk.
