 a very oblique- row or line of black dots, or aggregations of 

 minute black scales, representing a partial second line, which 

 usually does not approach the costa ; subterminal line a row 

 of more or less distinct black dots nearer the hind margin ; 

 cilia yellowish-white or brownish-white. Hind wings white, 

 dusted with brown, and very faintly tinged with reddish-
