(S ? . Spots on npperside of wings reduced in site, especially the disoal series 

 of hinJwinf^ ; the njiper two or three sjiots of the forewiug vestigial or missing in 

 most individuals. Specimens with exceptionally large spots scarcely distinguishable 

 from Ja/iira specimens with exceptionally small markings.

(??. Wings, upperside: forewiug with a submarginal row of four to seven 

 spots from hindmargin forward, the spots gradually decreasing in size. Hind- 

 wing : an evenly curved row of spots placed (in centre) halfway between cell and 

 distal margin, the upper two spots the smallest, the others of about eipial size, 

 the band broader in female than in male ; a row of admarginal spots, being the 

 remnants of transverse bars. 



On underside a row of heavy transverse red bars on hindwing, the u]>per bars 

 bearing at costal side a silvery spot, at the distal side of which there is a rather large 

 creamy admarginal dot, in cellule R^ — M' two silvery dots and two creamy ones, 

 in cellule M' — M^ the silvery and the creamy dot standing at posterior end of red 

 bar — i.e. at vein M'^, not at M'. 



Scent-organ : a streak of dense erect scaling as in the allied species, the .scales 

 twice as long as broad or less, multistriate, nearly as broad at base as at apex. 



Genitalia as in P. belus, tenth tergite a little slenderer. 



Early stages not known.

We have not seen a si)ecimen agreeing with Esjier's or Martyu's figures of 

 amulius, in which the submarginal spots on the underside of the hindwing are 

 yellow instead of red. We believe this insect to le a xantliochromati(^ female of 

 belus. Martyn's figure is better than that of Esper. Tiie yellow spots on the 

 up|ierside of the hindwing as shown in Martyn's figure are rather often limiid in 

 females of belus, but are not so pure yellow. 



<?. Scaling of body and wings practically as in /'. li/c/das. No white streak 

 along abdominal fold of hindwing, red sjiots on underside farther away from 

 margin than in J', ii/cidas, accomjiauicd by white admarginal dots, which are
