Two local forms are known : — 



{(i): P. janaka Moore, forma typ. [c?,?]. 



]\Ir. Wood-Mason described the liasal half of the hindwings as being " green-black " 

 in his P. sikkiinensis, which does not exactly fit to any of my janaha specimens ; 

 janaka-males have, however, sometimes an obvious olive-green tint on the hindwings 

 above, which may change into green-black in discoloured specimens. 



P. janaka Moore differs from P. hooles Westw. especially in the tooth in front 

 of the tail of the hindwings being more directed backwards, in the apical spots of the 

 tails standing rather nearer to the apical margin of the tail, and in the red basal area 

 of the underside of the hindwings being extended along the abdominal margin and 

 joined, or almost so, to the red spot at the anal angle. 



The gromid-colour of the fenuile is paler than in the nude ; the hindwings have 

 three large white discal patches, and a smaller spot before the upper discoidal vein ; 

 the submarginal markings are large. 



Though the differences between janaka and hootes are slight, (hey are apparently 

 constant, at least injaiuika from Sikkim and hootes from Assam. Our knowledge of 

 the two insects is, however, very limited. As it seems to me rather improbable that 

 each of the two has such a very restricted range, I am convinced that the two insects 

 come together in Bhootan and probably mix with one another. 



The spots at the tip of the tails are very variable in size ; one of my si)ecimens 

 has one six)t only instead of two on each tail.

{h) : P. janaka dealbatus subsp. nov. [cJ]. 



S . Differs from P. janaka, Moore in the same way as P. hootes Hii/ricans m. 

 does from P. hootes Westw. I have a single male only, which exhibits the following 

 characters : — 



A little smaller and much deeper black \hnn P. janaka Moore. Hindwings, 

 ^ipperside, without discal white patches, but with a dispersed buff scaling all over 

 the wing, exclusive of the nervules and the internervular folds; (he two red spots 

 at the anal angle separated from one another ; a thin submarginal lunule between 

 (he lower median nervules; tails all black, much less sjjatulate than in janaka. 

 Hindwings Imlov) with six submarginal spots, of which the first (behind the cos(a) 

 is very small, the second and third a little larger, but still small and linear, 

 the fourth slightly, the fifth and sixth strongly arched; there are two red spots
