both fore and hind wings. 



The Banded Footman, Cisthene unifascia (Cis-the'ne

 Atlantic States from New York to Texas. The 

 fore wings are lead-colored, and crossed by a

There is much variation in the width of the yellow band.

These moths are most easily distinguished from the allied 

 families that are rep-

 Here we find the
