A specimen in the collection of the Philadelphia Academy has 

 been labeled by Fernald as the probable tj^pe. Since it matches the 

 description and agrees with the general concept of the species it 

 may be so regarded. 



The metallic spots are duller in agilana than in the other dark 

 species with similar markings; but in fresh unrubbed specimens are 

 easily seen without a lens. They only become completely obscured 

 in greasy specimens. 



Male and female genitilia figured from specimens in National 

 Collection from Ithaca, N. Y. (male, reared, E. H. Hausman, May, 

 1920) and Oak Station, Pa. (female, F. Marloff, "June 10-07").
