nervule ; there is a series of triangular black spots on outer margin placed on the nervules, 

 their bases united and the apical ones more or less confluent. Secondaries have a black bar 

 at end ot cell, a submarginal series of black spots extending from costa to second median 

 interspace and a series of small triangular black spots on outer margin, placed on the nervules 

 and united by a black marginal line. Fringes of primaries black except towards inner angle, 

 ■where they are greyish as are those of secondaries. Under surface : venation broadly black ; 

 apex of primaries yellow ; secondaries yellow, the area beyond the blackish submarginal 

 baud and also the abdominal margin paler ; there is a patch of deeper yellow at the base of 

 costa, and one below median nervure. 



Female. Black markings more pronounced ; all the wings are traversed by a black band and are 

 suffused with black on the basal area. Under surface similar to that of the male but the 

 secondaries are rather whiter. 



Expanse, S 70 millim., $ 68 millim. 



The female of P. (Judeniardi, which has not been previously described, 

 appears to be scarce, but the male seems to be common from May to July at 

 liigh elevations in the neighbourhood of Ta-chien-lu, Ni-tou. "Wa-ssu-kow, and 

 Chow-pin-sa, Western China. M. Oberthiir's type was from Tsekou. 



Referring to this species, Mr. Elwes says, in his " Catalogue of the Lepido- 

 ptera of Sikkim " (Trans. Eut. Soc. Lond. 1888, p. 415) : — " This species is 

 only known to me from some eight or nine specimens which were brought by 

 a native employed by the late Capt. Harman, E,.E., in surveying the Thibetan 

 frontier, and may not occur on this side of the passes." -
