This species was first described by Godart from Brazilian specimens, from which 
country we have also obtained it. We have no knowledge of its occurrence northward 
of this till we reach Costa Rica, whence we have received several examples differing 
in no material respect from our insects from Rio Janeiro; but there is a certain amount 
of variation in individuals from the same locality, no two being exactly alike. We have 
one from Costa Rica which has the mark at the base of the primaries and the whole of 
the interior area of the secondaries dark ferruginous, the latter not being divided by black 
nervules till close to the outer margin. We have also a single Guatemalan specimen 
sent by Mr. Hague from the Polochic valley; in this all the fulvous markings are 
orange, but the black veining of the secondaries is strongly shown. These, however, 
are extreme cases; and we are unable to point out constant differences whereby the 
northern insects can be separated from the southern. 
The distribution of E. vibilia is one of the many instances we have to bring forward 
of the close connexion of the Central-American and Brazilian faunas, these widely distant 
countries being occupied by allied and even, as in this case, by the same species, the 
intervening tract of land being devoid of them.
