1891.] THE NAGA AND KAREN HILLS AND PERAK. 285 



R. polynice of Cram., as I have no Javan specimens ; but I cannot 

 separate it from those found in Sumatra, and have little doubt that 

 Guerin's plate represents a female from the Malay Peninsula, as I 

 have one from Nias Island which almost exactly agrees with it. 



Dohertv took two in the Dhansiri valley of Assam, a single speci- 

 men at the foot of the Karen Hills, and a pair at Perak, which agree 

 with others from Mergui, Nias. and Sumatra. 



Rhinopalpa vasuki.

Yoma vasuki, Doherty. 



I received several pairs of this species from Mr. Doherty, taken 

 near Momeit in Upper Burmah. As they are rather variable I should 

 hardly have seen sufficient reason myself to separate it from R. sahina. 

 Cram., which is found in Java and Amboyna ; but as I have but one 

 specimen of the latter for comparison, and Mr. Doherty knew both 

 species better than I do, I have followed him in treating it as distinct. 

 His remarks already given (above p. 258) should be noted. 



LiBYTHEA NARINA. 



Libythea narina, Godt. Enc. Meth. ix. p. 1/1 (1819). 



Libythea rohini, Marsh. J. A. S. B. xlix. pt. ii. p. 248 (1880); 

 de Nicev. Journ. Bomb. Nat. Hist. Soc. 1890, p. 208 ; Butt. Ind. ii. 

 p. 303, t. xxiv. 114 (?). 



Doherty sent two specimens of this taken in the Dhansiri valley of 

 Upper Assam in June 1889, and found it common near Momeit in 

 Upper Burmah in June 1890, at about 2000 feet. 



It agrees very fairly with specimens from Celebes and Amboina 

 in Mr. Godman's collection, which confirms the identification made 

 by de Niceville, and cited above. There is some variation in the 

 size and colour of the spots and band above and of the markings 

 beneath, but the species is perfectly distinct from either of the 

 others found in India. 



Araschnia PRORSoiDES, n. sp. (Plate XXVII. figs. 5 d"j6 5 .)

This is one of the most interesting additions made by Mr, Doherty 

 to the Indian fauna and was taken abundantly by him above Mao, on 

 the Manipur side of the Naga Hills, at 6000-8000 feet elevation, in 

 Aug.-Sept. 1889, where it was common in open ground near water ; 

 the larva feeds on a species of nettle. I identify it with Bianchard's 

 species by a specimen taken by the Abbe David at Moupin, which I 

 received under that name from the Paris Museum, and which agrees 

 with numerous others taken by Mr. Pratt at Ta-tsieu-lo in East Tibet. 



It is nearest to the large form of L. levana var. prorsa found in 

 Japan, but may be distinguished by the narrower and straighter 

 white band of the hind wings, beneath by the absence of the broad 

 chocolate outer band.
