 broad on the eosta, below ihe median vein parallel with the outer line, and 

 not lonehins il. ( )ufer ((iiird ) line very simions, with a large reetangular 

 l)cii(l opposite the discal ring; the line enrves inward to the point of the

This common species seems to l)e divided into two races, one smaller 



and darker, with the antenna? more l)roadly pectinated, while the outer line 



on the hind wing is less angnlated, but it is difficult to draw a line between 



them. The si)ecies may at once ))e known by the very sinuate outer line on
