125. Parnassius epap/ms sikkimensis, Elw. 108 specimens on the 

 Putreng La and the passes to the south of the Tsang Po August and 

 September, 14,500 to 16,300 feet. Amongst them several virgin females. 

 T^ ^^\^ -P«'•'^«ss^■^<s imperator intermedia, Rothsch. 32 specimens on the 

 KonghbolNgaLaand the passes to the south of the Tsang Po August 

 and September, 14,500 to 16,300 feet. This race is quite different in 

 appearance to the very distinct yellow race augustus, Fruh. from the 

 Uiumbi Valley ; the ground colour is pure white and the black dustine of 

 the nymotypical form is absent. ^ 



^T^?J' ^f''^ belladonna lativitta, I^eech. 11 specimens in the Po Chu 

 Valley and at Pemako Chung on the Tsang Po, 7-9,000 feet, July.

133. Aporia larraldei melania, Oberth. 2 c? and 1 $ in the Po Chu 

 Valley and at Pemako Chung on the Tsang Po, July, 10 000 feet 



The specimens obtained were more or less intermediate between ^nelania 

 and paracraea, de N. below as pamcraea, above as melania : karrietae de N 

 from the Bhutan Frontier, of which as far as I know only the type pair 

 exists m the Calcutta Museum, is also very close. The variation in larraldei 

 seems to be very similar to that in affathon and possibly many of the 

 so-called races are really only varieties of the pale nymotypical form.
