 figs. 3, 4 (1848). 



JR. nissa, Butt. Ind. iii. p. 463. 



Only sent from the Naga Hills, where it does not seem to be 

 so common as it is in the Khasias.

Rapala suffusa. 



Deudorix suffusa, Moore, P. Z. S. 1878, p. 834, t. Iii. fig. 8 c? . 



B. suffusa, Butt. Ind. iii. p. i&Q. 



Deudorix barthema. Distant, Rhop. Mai. p. 280 (1885); Butt. 

 Ind. iii. p. 450; Doh. J. A. S. B. Iv. pt. ii. p. 260 (1886). 



Mr. de Niceville's supposition that these names would prove 

 synonyms is correct, as I have a male from Perak named by himself, 

 together with two females from East Pegu, which agree with it in 

 the yellow colour of the underside, and with a female from Barakhal, 

 Chittagong, taken by Doherty and alluded to by him in writing of 

 D. harthema. Bapala suffusa is a perfectly good species, and the 

 female may be known from the female of B. xenophon by the pale 

 yellow of the underside. 



1 have another species with pale yellow underside in both sexes 

 from the Khasia Hills which is a Deudorix, having no sexual mark in 

 the male, and is larger than B. suffusa, but though I cannot discover 

 a name for it the specimens are not good enough to describe. 



Rapala jarbas. 



Papilio iarbas, Fabr. Mant. Ins. ii. p. 68 (1787). 



B. jarbas, Butt. Ind. iii. p. 468. 



Sent from Bernardmyo and Perak. 



Rapala hypargyria, n. sp. (Plate XLIII. fig. 7, J .) 



Doherty sends five specimens of this very distinct species from the 

 Karen Hills, all of which appear to be males. Above they are most 

 like B. xenoplion, but of a more orange tint, with a broad black 

 border on both fore and hind wings, the latter fringed towards the 

 anal angle, and more conspicuously on the inner margin, with white ; 

 a dark streak runs from the base of the tail parallel to the inner 

 margin. Beneath, the fore wing is dull silvery white, tinged with 

 brown towards the costa and outer margin. Hind wing the same, 

 with an obscure row of spots towards the anal angle. The anal lobe 

 and a large round spot above the base of the tail black, a short 

 broken line from near this towards the inner margin. 



Frons, palpi, and breast white ; abdomen fulvous. Head and 

 thorax black. 



Expanse 30-38 mm.
