1882.] MR. H. J. ELWES ON BUTTERFLIES FROM SIKKIM. 401 



Ladak at 10,000 feet; besides three others ia 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 F. sikkimetisis, showing, if my views 

 are correct, that the species are constantly different, though they 

 occur together iu 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 

 occurs at tliis 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. silckimensis. 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.

1 cannot see any reason to separate this from the European insect. 

 A series of specimens from Sikkim, Nepal, and Kaslimir average 

 larger than British ones, but not larger than some I have from Asia 

 Minor ; and there is nothing in colour to distinguish them. There 

 were many examples in the present collection. 



PiERis AJAKA, 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 Ainurland and Japan (cf. 

 P. Z. S. 1881, p. 876). 



It is intermediate between P. melete and P. napi above, and 

 resembles the form bri/onice beneath. Similar specimens from the 

 Khasia hills are in my collection. 



Delias belladonna, Fabr., Gra}', Lep. Ins. Nepal, t. 8. fig. 2. 



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.
