328 Mr. H. J. Elwes’ catalogue of the 
but two which were contained in Wilson’s Sikkim col- 
lection are somewhat larger than those from Kulu and 
Nepal, and are intermediate between it and C. scanda. 
The types of annada were taken in Bhotan by Pemberton, 
and C.scanda is recorded by Moore from Darjeeling. 
Until more specimens are procured it must remain doubt- 
ful as to whether a Callerebia exists in Sikkim, and, if 
so, to what species it belongs. 
C. hyagriva (Ypthima hyagriva, Moore, Butt. Ind., i., 
p. 226, t. xvil., 64, 2) is also recorded from Sikkim, but 
[I have never seen a specimen except from Kulu. 
77. Zipetis scylax. 
Zipatis scylax, Hew., Ex. Butt., iii., p. 100, t. Zipetis, 
fig. 7 (1863); Butt. Ind., p. 249, t. xvii., 62, 2. 
Not a common species in Sikkim, and only found in 
low, hot valleys at 1—38000 ft. from May to November. 
I took it near the Tista Bridge in August, and noticed 
that its flight and appearance were similar to those of 
an Ypthima. 
78. Melanitis leda.

P. ismene, Cram., Pap. Ex., i., t. xxvi., A,B (1775).

t. XL, 4. 
’ M. bela, Moore, Cat. E. I. C., i., p. 228 (1857) ; Butt. 
Ind., i., p. 568. 
Not so common in Sikkim as in the plains, but it occurs 
all the year round at low elevations, and I have taken 
M. leda in July as high as 7000 feet. 
After de Nicéville has proved by breeding that the two 
very distinct-looking insects known as leda and ismene 
are, in Calcutta at least, only seasonal forms of the same 
species, I confess I do not very well know how to treat 
the other forms of the genus occurring in Sikkim, of 
which Moller recognises three, namely :—
