ferruginous above : eyes dark-brown, with a moveable black 

 pupil : mouth pale : neck light-green, with a brown, transverse, 

 hirsute collar on the middle: thorax dark ferruginous, hairy, 

 blackish each side : feet pale : superior wings dull ferruginous, 

 with numerous opake, transverse, abbreviated, black lines; a 

 small black point at the inner basal angle/and a small transverse, 

 abbreviated dusky line on the inner margin a little beyond the 

 middle ; inferior wings light honey-yellow, a blackish, dilated, 

 angulated, semifasciate line near the tip, and a black, anterior 

 spot near the inner margin : pectus pale-brownish. 



Obs. This species frequently occurs in various parts of the 

 United States. It is an inhabitant of Pennsylvania and New 

 Jersey, and I also found specimens near the falls of the Ohio 

 river; and another was sent to me by Dr. T. W. Harris, of 

 Massachusetts. A variety in my cabinet, is altogether destitute 

 of the semifascia on the inferior wings.
