Yelvely black. Primaries have three white central spots, the third much smaller than other two, 

 and five subapical ones, the fifth hardly discernible ; fringes black except at the apes, where 

 they are white. Secondaries have two white central spots similar in shape to those of 

 P. Jlavniiiacnlnfa ; fringes white. Under surface of primaries blackish, washed with 

 olivaceous along costa and on apical area ; the white spots of upper surface are reproduced, 

 and there are two additional pale spots below apex, and some ill-defined oaes precede and 

 follow the central spots : secondaries olivaceous, marked with white at base of costa and 

 inner m:irgin ; there are nine silvery spots placed as follows — one subbasal, five forming a 

 central band, two at outer angle, the upper not clearly defined, and one in each median 

 interspace towards outer margin ; a short white streak is jtlaced between centi'al band and 

 lower spot of the two at outer angle ; fringes white. Antennae black, finely ringed with white 

 beneaih, underside of club is also white. The sexes are alike in colour and marking. 



Expanse 32 millim. 



Occurs at Ta-chien-lu and Wa-ssu-kow.

This form, which occurs ill the Amdo plateau, Thibet, differs from the type 

 on upper surface in having rather more white at apex of primaries and a 

 white patch at base of these wings ; the central spots on secondaries are con- 

 fluent and form a large patch.

Allied to /'. iiircontKciildlit, Olx'rlhiir, liut on the up])er surfiicc the jiriniarics have a while 8j)ot at 

 the l)asc of the cell, another towards outer end of cell, and four smaller ones beyond, forming 

 in conjunction with Uic four apical spots an interrupted band; the secondaries have one 

 large white central h])i)(, and in some specimens there is a snuiller spot below it. The under 

 surface of ])rimarie8 is dashed with silvery white along the base of the costa, and, in 

 addition to the spots as above, there is a silvery-white apical cloud ; tlui secondaries have 

 two broad silvery-whit(! bands from costa to submcduin ncivule, which is dashed with the 

 same colour, as also is t lus base of costa.
