SUBFAMILY III. ATTELABINJE. 



63 



ber, rolling leaves of sumac. Described from Georgia and re- 

 ported from Florida. Eanges from Massachusetts to Kansas and 

 Colorado. Sumac is probably the only food plant, its occurrence 

 on other foliage being accidental. LeConte, in his original de- 

 scription, states that the breast of niyripes is black and its 

 length 3 lines (0 mm.). The species herewith described as ni- 

 gripes differs in these characters, but it is the one known under 

 that name in most collections.

 Michx.). The eggs, which were deposited in late April, hatched
