Subfam. 6. Nymph alii®. 
To prepare a key for the identification of the genera of this largo subfamily 
so that they fall into one particular sequence has proved too much for me ; 
I have, therefore, abandoned the attempt, and adopted more or less Bingham’s 
arrangement for the Indian genera. As explained by Fruhstorfer, it is quite 
impossible to rely on any one character to distinguish Nymphaline genera ; 
any attempt to do so must result in an artificial arrangement; however, as 
identification is the object of a key, arrangement in sequence (which is still 
indicated by the numbers in front of the genera) is considered here of secon¬ 
dary importance. 
a. Fore wing: costal nervure greatly inflated at base. 
b. Males with large dark glandular patch from median nervure 
to inner margin on under side of fore wing. Colouring 
above rich ochreous brown ...... 24. Ergolis. 
b\ Males without glandular patch. Colouring above blue in 
males, olive fuscous in females . . . . .25. Laringa. 
a 1 . Fore wing : costal nervure not inflated at base. 
b. Fore wing : costa not serrated. 
c. Fore wing: fourth subcostal nervule ending on costa 
well before apex.26. Cupha. 
c 1 . Fore wing: fourth subcostal nervule ending at or near 
apex or on hind margin. 
d. Cell of hind wing closed. 
e. Fore wing: second subcostal nervule emitted well 
beyond apex of cell. 
/. Fore wing: first subcostal nervule emitted well 
before apex of cell ...... 27. Atella. 
f 1 . Fore wing: first subcostal nervule emitted from 
apex of cell ....... 28. Issoria.

apex of cell or just beyond cell.

g. Male with large velvety patches of specialized scales. 
Hind wing angulate. Colouring above violet 32. Terinos.

usually not angulate, but, if angulate, colouring 
above not violet.

i. Fore wing: third median nervule not strongly 
arched. 
j. Hind margin of both wings scalloped 35. Vanessa . 
j. 1 Hind margin of fore wing not scalloped; not 
deeply excavate, unless hind wing is tailed. 
k. Hind wing without prediscoidal cell. 
1. Fore wing not elongate.
