color of the anterior wings yellow. A broad, basal, black band, en- 

 larged on the costa, extends obliquely to the inner margin. Beyond this 

 band the wing is yellow, until a median, broad, slightly arcuated band, 

 corresponding to the median shade. The exterior line is also black, 

 narrower than the other two, arcuated on the costa. It is followed by 

 a narrow, partially obliterated line of the ground color. Beyond, the 

 terminal and subterminal spaces and the fringe are black. The pos- 

 terior wings are fuscous, tinged with yellow, crossed by three very 

 broad, diffused gray bands, separated by the ground color. Beneath, 

 the anterior wings are yellow at the base ; the terminal and subterm- 

 inal spaces are gray. The median space is occupied by two broad, 

 diffused, gray bands. The posterior wings are lighter in color, but 

 are banded as above. The anterior femora are blackish. The middle 

 legs are yellow, but have the ends of the tibise distinctly black. The 

 abdomen has a yellow anal tuft.

Larger, and quite distinct from the species described by Guenee, and 

 from X. fax Grote. E. coccineifascia and rosaba, figured very poorly 

 by Mr. Grote in the " Transactions of the American Entomological 

 Society," Vol. x, pi. i, figs. 88 and 89, are erroneously placed in this 

 genus by him ; they should be referred to Profhymia Hb. E. rosaba 

 is closely allied to the European aznea Hb., and -strictly congeneric 

 with it. 



Our species of the two genera will now stand as follows: —

This is a very small, slight-bodied species, quite distinct from E. mus- 

 cosula Guen. and its allies. The ground color is pure white, with the
