the genus Ypthima. 5 
six ocelli near the margin of the hind wings above ; the 
under side is, in the majority of the species, whitish or 
yellowish grey, with a number of close short irregular 
curved transverse brown striole, and the hind wing bears 
from one to seven ocellinear the margin. ‘This peculiar 
marking of the under side is, as far as we know, with one 
exception (Callerebia hyagrwa, M.), confined to the genus 
as here limited. ‘The first subcostal nervule in the fore 
wing is emitted before, at, or beyond the end oi the cell; 
but the second subcostal nervule is never emitted betore 
that point; the middle disco-cellular is generally arcuate, 
not elbowed, and the tegumen is nearly always elongate, 
triangular, and simple. In writing of this genus it ap- 
pears customary to transcribe Westwood’s definition (Gen. 
Diurn. Lep., 394) in extenso, but this, as is too frequently 
the case, substitutes long details of structure for precise 
words of limitation. ‘he only point of any value upon 
which writers on this group are agreed, 1s the circum- 
stance that in no case 1s more than the first subcostal 
nervule emitted before the end of the cell; if we add to 
this the general facies, and the simple uncus, this com- 
bination of characters enables us to limit with precision 
a fairly natural group of reasonable extent; and, having 
regard to the fact that the dithculty of limiting genera 
increases in proportion to the natural affinity inter se of 
the species to be classified, this is all that can fairly be 
expected. 
‘his course, however, leaves to be accounted for two 
insects which have at one time or another found a place 
in the genus under consideration, namely, narasingha, 
Moore, and hyagriva, Moore. ‘lhe latter possesses so 
many of the characters of Callerebia, that it is perhaps 
best placed in that genus as a matter of convenience, 
notwithstanding that its facies is, if we except the 
broadly-rounded fore wings, Ypthimoid. ‘I'he tormer 
would fall well into Callerevia, it 1t were not that the first 
subcostal nervule only is emitted before the end of the 
cell; and in this connection it should be mentioned that 
out of two males and four females examined we found 
one male in which both the first and second subcostal 
nervules are emitted before the end of the cell, a feature 
which would, in conjunction with the elbowed middle 
disco-cellulars, the tridentate uncus, and the general 
facies, make this specimen at least a Callerebia. ‘The
