EASTERN UNITED STATES. 125 



nearly one-fourth the length of the fore wing, but about 

 half as wide on the hind wings; crenate on the inner 

 edge on the fore wings. 



Under side paler yellow than above, but orange-tinted, 

 scarcely darker than the under side of the male Sennce; 

 nearly without marks. At the end of the cell of the 

 fore wings there is usually a small blackish-brown spot, 

 with or without a few rosy scales, some examples not 

 having either the black or the rosy. There is a more or 

 less distinct oblique stripe of dark scales extending from 

 near the apex to near the hind margin, usually stopping 

 at the lower branch of the median, opposite the lower side 

 of the cell, almost half-way from the outer edge to the cell. 

 The hind wings have at the end of the cell a faint dark 

 brown circle, and one in the interspace above outside 

 the cell; in some examples scarcely a trace of these. 

 Besides these there are traces of a submarginal row of 

 spots, and a row through the end of the cell like Sennce, 

 but they are represented by a few scattered scales or not 

 at all ; also some scales in the places along the costa and 

 near the base of the cell, representing an inner row. 



Female. This is more of the color of the dirty yellow 

 form of Sennce, or dirty whitish yellow. At the end of 

 cell of fore wings an elliptical blackish-brown spot ; the 

 costa blackish brown, the costal margin sprinkled with 

 this, the apex blackish brown ; along the outer margin 

 a series of brown semi-oval spots at the ends of the veins, 

 which are not quite connected, these extending along the 

 hind wings nearly to the anal angle. Extending from 

 the apical patch on the fore wings is an oblique row of 

 six spots separated by the veins, and three smaller ones 

 in the subcostal interspaces. The hind wings have three
