178 Mr. H. W. Bates on the Nymphaline 
closely allied through Amathusia to Kallima, the larve of which 
latter genus, discovered by Dr. Doleschall in Amboyna, have, ac- 
cording to Dr. Felder, great resemblance to those of Junonia and the 
Vanesse. As the larve of many of the other genera of Morphide 
have forked tails like the Satyridee and most of the Brassolide, and 
are moreover related by the same character to the larvee of Apatura, 
we have at once evidence of the close alliance of the Morphidee with 
the Nymphaline, and a proof of the intricacy of the relationships 
which bind all the genera of Nymphaline together. These facts also 
show that the resemblances between the larvee are not borne out by 
those existing between the perfect insects of this family; although 
a similar form of larva does undoubtedly persist through many 
genera of this subfamily in harmony with resemblances between the 
imagos. 
The Eurytelid seem to have still less right than the Morphidee to . 
constitute a separate family ; for none of the genera, except Melanitis, 
possess anything in their structure to remove them from the neigh- 
bourhood of such genera as Crenis or Pyrrhogyra. Melanitis differs 
from the rest in the males of the perfect insects having pencils of 
hairs on the hind wings, and in the larve having cephalic spines, 
forked tails, and a smooth skin—characters which reveal a relation- 
ship to the Apatura group, several genera of which have in the male 
sex similar appendages on the hind wings; and to the eastern mem- 
bers of the Morpho group, near which and the Satyrine Melanitis 
ought to be placed. The larvie of the other genera, or at least such 
as are known, have all the characters of Nymphaline of the Callithea 
group; that is, spinose bodies, and heads surmounted by branched 
spines. The larva of Didonis resembles that of Ageronia, in the 
neighbourhood of which the genus would find its true position ; 
Eurytela, Ergolis, and perhaps Hypanis would be better placed near 
Crenis and Eunica ; Olina and Cystineura in the vicinity of Victorina 
and Pyrrhogyra. 
It will be apparent from these details that the subfamily Nympha- 
line, although containing a great diversity of generic types, can 
with difficulty be classed even into groups of genera. Some sort of 
subdivision, however, is highly desirable for the sake of facilitating 
the study of so extensive an assemblage, which now comprises no 
less than 120 genera and 1200 described species. As far as the 
American members are concerned, the genus Morpho may be detached 
from the rest, and formed into a subdivision characterized by the 
great size of the insects and the shape of the discoidal cell of the fore 
wings. As to the remaining genera, I have tried in vain to discover
