Mamestra ascula, n. sp.— Ground colour very pale ashen gray, with a somewhat luteous tinge more or less obvious in most specimens; best marked in the male, most frequently wanting in the female. The ordinary lines are all broken and obscured by the shading, yet all distinctly traceable, geminate, one part of the line blackish, the other smoky and always partly incomplete. Basal line usually marked by a geminate spot on costa. There is a short black basal streak, best marked and a little curved in the female, and above it the basal space tends to be a litter paler.
