 median and subterminal lines indicated by a gathering of the dusting; the median 

 short, thick, oblique, in the middle of the disc, sometimes weakly continued to 

 the costa and inner margin; the- subterminal oblique, sinuous, nearest outer margin 

 opposite the cell; veins toward the apex often streaked with pale gray and edged 

 with the brown scaling. Seven terminal dots; fringe golden bronze. 20 mm. 



Larva on grass and sorrel. Moth in August and September. 



Common south to Pennsylvania and Missouri. New York: Ausable Lake,

 with the ground color; and with scattered black scales. Median line usually 

 reduced to a black patch in upper part of fold near end of cell, irregularly oblique 

 when more distinct; subterminal line usually reduced to dots, nearly parallel to
