1882.] MR. H.J. ELWES ON BUTTERFLIES FROM SIKKIM. 401 
Ladak at 16,000 feet; besides three others in Mr. Godman’s collec- 
tion from Lapsang in Ladak, 17,000 feet; and a single specimen, 
which agrees perfectly in all the characters I have mentioned with 
these, and is intermediate in size between P. acco and P. simo, was 
among my fourteen examples of P. sikkimensis, showing, if my views 
are correct, that the species are constantly different, though they 
occur together in similar localities 800 or 900 miles apart.

A very variable species, found from Kashmir to Sikkim, from about 
8000 feet up to 15,000. The variety named P. charino by Gray 
oceurs at this great elevation in Ladak ; and four specimens, which 
agree with his plate in being of much darker colour than the common 
form, came with P. sikkimensis. It may be known with certainty 
by the five blue eyes on the hind wing, which, so far as I have seen, 
are never wanting, though sometimes reduced to spots.

P. nipalensis, Moore, P. Z.S. 1865, p. 490. 
I cannot see any reason to separate this from the European insect. 
A series of specimens from Sikkim, Nepal, and Kashmir average 
larger than British ones, but not larger than some J have from Asia 
Minor; and there is nothing in colour to distinguish them. There 
were many examples in the present collection. 
Pieris ayAKA, Moore, P. Z.S 1865, p. 490, t. xxxi. fig. 16. 
A single female of an insect which for the present I refer to this 
species, which, however, I do not see how to separate from the forms 
which I have alluded to previously from Amurland and Japan (cf. 
P. Z.S. 1881, p. 876). 
It is intermediate between P. melete and P. napi above, and 
resembles the form dbryonie beneath. Similar specimens from the 
Khasia hills are in my collection.

It seems to me that there are two species confused under this 
name. ‘Those I have from Nepal agree perfectly with Gray’s plate ; 
but the Sikkim form, of which I have now secured several speci- 
mens, has in most cases no yellow on the anal angle or interior margin 
of hind wing. In some specimens, however, there is a trace of it; 
so that without knowing more of the intermediate forms in distri- 
bution, I should hesitate to separate this form.
