Mr. Grote, in his description of E. cinerosa, states that he formerly regarded it as 

 the female of E. mclanchoHca ; his opinion seems to have been changed by some remarks 

 of Mr. Gundlach, which, however, apply perfectly to good examples of E. cenotrus <* 

 (melancholica, Grote).

This appears only to differ from D. gutturalis in being somewhat larger ; I rather 

 doubt its being distinct, although Mr. Grote had both species before him.

" It has altogether the character of (Enothrus of Cramer and of Oinphalecc of Central

 inferior wings, since they are yellow or fulvous, with a black border, in all the known 

 species." — Boisduval.
