We have no hesitation in restoring Graeser's name for this species, as we have 

 examined three typical specimens kindly lent to us by Mr. Dieckmann. As a result 

 of the reduction of the silvery markings on the hind wing below, a specimen from 

 Koslofska, in coll. Dieckmann, has the roundish spot proper to the cell barely indicated.
