A very variable species easily recognized by its peculiar horn like 

 socii. The latter project caudally from the tegumen and look at first 

 glance like the parts of a widely divided uncus.

This is only a rather large and very pale color variety of nisella, 

 and should probably not even have a varietal designation. The 

 genitalia agrees in detail with those of typical specimens of nisella, 

 I am keeping Kearfott's name for the present on the chance that it 

 may apply to a food plant race.
