Mr. Grote, in his description of E. cinerosa, states that he formerly regarded it as 
the female of #. melancholica; his opinion seems to have been changed by some remarks 
of Mr. Gundlach, which, however, apply perfectly to good examples of /. wnotrus 3 
(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 @nothrus of Cramer and of Omphalew of Central 
America, but is easily distinguished from all the Sphingide of this genus by its black 
inferior wings, since they are yellow or fulvous, with a black border, in all the known 
species.” —Boisduval.
