186 Mr. H. W. Bates on the Nymphaline 
LEPIDOPTERA DIURNA. 
Family Nymphalide. 
Subfamily Nymep HALT NH. 
Group NymeHALirs. 
Genus Conanis, Doubleday. 
The species of Colenis are seen only in open, sunny places ; such 
as waste grounds, gardens, and the borders of woods, where flowering 
bushes grow. ‘They are never found in the great forest, but seem 
to*be attendants on man, making their appearance wherever a clear- 
ing is commenced in the woods. They have not a very rapid flight, 
nor much of the floating mode of progression when on the wing, but 
move about somewhat irregularly and settle frequently, their attrac- 
tion being always flowers, and never moisture or filth on the ground, 
as is the case with the more typical genera of Nymphaline. There 
can be no doubt that the Colenes are closely related to the Heli- 
conine (Heliconius and Eueides); indeed the only difference of im- 
portance is the absence of a lower disco-cellular nervule from the 
hind wings—a character which brings them within the pale of the 
Nymphaline. The genus is related, on the other hand, to the 
Argynnes of temperate climates, through the genera Agraulis and 
Clothilda. 
1. Colenis Dido, L. 
This handsome and well-known insect is generally distributed 
throughout the Amazons region, its great expanse of wing and 
clear grassy-green colour making it a conspicuous object in all semi- 
cultivated places near settlements. Guiana and Amazonia seem to 
be the headquarters of the species. 
2. Colenis Pherusa, L. 
P. Phetusa, Cramer, 130 B. c. 
Also a generally distributed and common insect, found in com- 
pany with C. Dido. Its range seems to extend farther to the north 
than C. Dido, as Mr. Osbert Salvin found it abundantly in Guatemala, 
where its companion did not occur. 
3. Colenis Julia, Fab. 
P. Alcionea, Cramer, 215 A. F. G. 
Equally common and widely dispersed with O. Pherusa. It 
ranges over nearly the whole of Tropical America.
