and apical portion of the costa white. The hind wings 

 have a prominent angle at the end of the first median 

 venule, a narrow terminal border ending before reaching 

 this angle, with scarcely a trace of a discal dot. The 

 female is a little more yellow. 



Under side yellow, except the posterior two-thirds of 

 the fore wings, which are almost white. Discal dots 

 more prominent than above ; a broken brown bar ex- 

 tending nearly across the hind wings from above the 

 anal angle, and some brown scales scattered over the 

 surface. 



This species seems to be gradually spreading over the 

 North and East ; the habitat as given in Mr. Edwards's 

 new catalogue being Texas, Arizona, Southern California, 

 Kansas ; occasional in Nebraska, Iowa, Illinois, and Wis- 

 consin, and Ontario, Canada ; the last four places having 

 been added since 1877.
