c? $ . Closely resembles P. latreillei, but can be distinguished as 

 follows : J . Upperside : ground-colour darker, not uniform, 

 distinctly darker on the basal half of the fore wing. Hind wing : 

 ground-colour on the basal side of the discal whice markings not 

 paler than the ground-colour beyond these ; an additional white 

 elongate spot, sometimes transversely divided into two, in inter- 

 space 5 ; a subterminal series of only three lunules in interspaces 

 2, 3 and 4 respectively, that in 4 white, no terminal crimson spot 

 at vein 3 or on tail. Underside similar to the upperside, but the 

 ground-colour paler and more opaque, the white markings more 

 or less tinged with crimson and a well-defined subterminal white 

 spot always present in interspace 6. Antennae, head, thorax and 

 abdomen much as in P. latreillei. $ . Similar to the tf , but the 

 ground-colour paler, the white markings on the hind wing larger, 

 the subterminal lunules more or less white.

S . Very closely resembles P. latreillei rf , but [judging by a 

 single specimen the fore wing is proportionately rather narrower, 

 the termen more oblique, the torn us more rounded. The markings 

 on the hind wing differ as follows : the discal white patch com- 

 posed of four elongate spots in interspaces 2-4, that in interspace 

 4 very broad, filling the interspace between the middle of veins 5 

 and 6 ; subterminal series of lunules larger than in latreillei, and 

 all vermilion-red, not crimson, both on the upper and undersides ; 

 cilia between tornus and apex of vein 3, apex of tail and cilia at 

 apex of vein 5 vermilion-red. On the underside, the spot of the 

 discal patch in interspace 1 is vermilion-red, and the red lunule 

 of the subterminal series in interspace 2 is produced to the ver- 

 milion-red terminal edging below it. Antennae, head, thorax 

 and abdomen as in P. latreillei. 5 " Appears to differ only from 

 the male on the upperside of the hind wing in the white patch, 

 which is continued posteriorly to the abdominal margin or nearly 

 so and does not extend into the end of the cell." (de Niceville, t. c.)

This seems to be a very rare insect, at any rate within Britisli 

 territory, only single specimens seem to have been taken so far. 

 Of these, one, a 3 , now in the British Museum, I took at over 

 5000 feet elevation, on the shoulder of the hillside on which were 

 built the barracks for the troops at Bernardmyo, in the Ruby 

 Mines district, Upper Burma.
