Early Stages. Unknown. 



It ranges through southern New England, westward to Wiscon- 

 sin, Iowa, and Nebraska, in a comparatively narrow strip of country.

 Carolina Skipper). 



Butterfly. On the upper side the butterfly is as represented 

 in the plate. The spots are repeated on the under side of the 

 fore wing, but less distinctly defined. The costa is edged with 

 brownish-yellow. The hind wings on the under side are yellow, 

 spotted with small dark-brown dots. Expanse, 6, i.oo inch. 

 The female is unknown. 



Early Stages. Wholly unknown. 



This species has thus far been found only in North Carolina, 

 and is still extremely rare in collections. The figure in the plate 

 represents the type. I have seen other specimens. I place it 

 provisionally in the genus Lerema, though it undoubtedly does 

 not belong here, and probably may represent a new genus. 

 Lacking material for dissection, I content myself with this 

 reference.
