This is tlix.' common typical American form, Gucnde's var. A. I have no 

 European exam|)les with which to compare it. Three Iceland specimens 

 only differ fiom these in the median band bein<i' less roseate, and with a 

 decided brownish tint. Tiiis is Guenee's var. B. 



Tills form may be recognized by the simple antenna?, the pale, cpiite 



clear, asli-colored wings, and the broad, median, roseate band, limited within 



by Ihe conspicuous, black, .slightly-curved l)and.
