considerable variation in the genitalia of different specimens, but 

 only in the comparative width of the cucuUus of the harpe. This 

 is so marked in one specimen that I was inclined to name it as a 

 ncAv species. The wing pattern, however, agrees in every detail with 

 Kearfott's type. 



Male genitalia figured from type.

In the Kearfott collection in the American Museum there is a male 

 without locality label and named by Fernald who probably had com- 

 pared it with Grote's type. The male genitalia of the Kearfott speci- 

 men is here figured. 



In the National collection we have a rubbed specimen from Shovel 

 Mountain, Texas, determined by Kearfott, and two fresh, well- 

 marked specimens from Kerrville, Texas, agreeing in every detail 

 of pattern, color, and genitalia structure with the specimen deter- 

 mined by Fernald.
