314 Mr. H. J. Elwes’ catalogue of the 
specimens in the British Museum, said to be from 
Darjeeling, differ from mekara in haying a broader and 
more rufous band on the margin of hind wing above, and 
the male has five ocelli, whilst five male specimens of 
mekara in my collection only have four. The markings 
of the under side also are more irregular, as in L. 
chandica, to which this species is perhaps more nearly 
allied. The figures in ‘ Lepidoptera Exotica’ are not 
well coloured. There are two females in Moore’s col- 
lection which come nearer to mekara, and Mr. Knyvett 
has procured a pair from Buxa.

(1857). 
Lethe chandica, Butt. Ind., p. 149. 
Common at the same elevation and in the same 
months as D. mekara, and has very similar habits.

Lethe Europa, Butt. Ind., p. 149. 
This is not a common butterfly in Sikkim, as Mr. de 
Nicéville thinks, but he has taken it in October. It is 
probably rather an inhabitant of the plains, and only a 
straggler in the low valleys of Sikkim.

Lethe dyrta, Butt. Ind., i., p. 152. t. x., fig. 22, 3 @. 
Not a common species in Sikkim, but found almost 
throughout the year at elevations up to 3 or 4000 ft.

Not uncommon in the virgin forest from 7 to 8 or 
9000 ft. between the months of June and November. 
The female is rare, and resembles that of the very
