There are three male paratypes taken at the same locality from 
May 13 to 15. In these specimens there is a slight variation in the 
venation; in one wing of one specimen M-2 is reduced to a stump 
projecting from cell first M-2, in another specimen the vein does 
not reach the wing margin. One paratype is in the United States 
National Museum, the others are in the collection with the types.
