_The likeness of this curious species to the Mexican Nymphalid Morpheis ehrenbergt 
is remarkable, and since writing on that species (antea, p. 211) we find that the two 
are found, if not actually in the same district, at least in close proximity, a fact we 
were not aware of at that time. 
If these two forms assumed the similar colouring of the wings by mimicry, they 
must have for a long time coexisted in the same area. Their distribution now would 
show either that the Morpheis has been largely exterminated, or that the Hades has 
vastly extended its range. 
At San Isidro in Guatemala, Mr. Champion found this species in great numbers 
in cacao-plantations, under the forest trees, at an elevation of about 1500 feet. It 
settles beneath leaves like so many of this family. It was equally common near 
Chiriqui. ©

Eurybia is a strictly Tropical American genus, containing ten or twelve species, its 
most northern limit extending to Southern Mexico. Five species occur within our 
borders, none of which (excepting the somewhat doubtful FE. unvia) are peculiar. 
The specific characters of most of the members of Eurybia are not very constant, 
and the variations of both colour and size between individual specimens render the 
species difficult to define with precision. 
Setting aside the Brazilian H. carolina and #. pergea, which may be distinguished 
by their uncinate primaries, the remainder of the species may be divided by the

and Hyphilaria removed from his subfamily Nemeobiine.
