bidentate or entire. On the hindwing the scales of the central orange spots of the 

 discal row have also on the whole one tooth less than the upper and i30sterior discal 

 spots and the submarginal spots. 



Nenration : SC- of forewiug about halfway between SC and SO', the latter 

 often a little jirosimal of apex of cell ; D' before middle of cell ; subbasal cellnle of 

 hindwing narrow, long, PC angnlate. 



Genitalia : c?. Tenth tergite spatnlate ; sternite with a lateral lobe which is 

 more strongly chitinised than the rest of the steruite, divided by an obliipie 

 transverse depression or groove into two ridges. Clasper elongate-triangnlar, the tip 

 being rounded off; harpe ending in a long and slender, smooth, acute process as iu 

 P. anchisiades, the nearly straight ventral margin bearing in the middle a prominent 



tooth ; the short dorso-apical edge oblique, dentate. ? . Armature of the same 



type as in P. anchisiades ; edge of orifice proximally produced into a long lobe 

 ■which widens apically, the apex being truncate and bearing some teeth ; anterior 

 surface of lobe longitudinally impressed, posterior surface carinate, except at apex ; 

 sides of orifice raised into a smaller lobe or ridge ; behind orifice a membranous 

 tubercle densely covered with minute hairs ; a large lateral ridge, dentate, gradually 

 becoming lower towards the mesial line of the body, curving towards the middle 

 lobe on the anterior surface of which it disappears ; between this ridge and the 

 orifice on each side of the latter a large dentate lobe which stands iu connection 

 with the lateral ridge as well as with the elevate edge of the orifice. Bristles on 

 inner surface of anal segment numerous but short.
