 below rather enlarged.

Both sexes tailed. 



The white marginal fringe of the forewings is not interrupted at the veins. 



The hindwings vary obviously in length; their submarginal spots are variable 

 as in P. demetrius Cram. My specimens from Western China, which belong to the 

 spring brood, are distinguished by the convex, not concave, outer margin of the 

 forewings, which are deeper black below and above, and by the deeper red submarginal 

 spots of the hindwings. The individuals fi-om Kiu-Kiang stand intermediate 

 between that Western Chinese and the Japanese forms. In all Japanese specimens 

 the submarginal spot between the upper median nervules shows a tendency to 

 obliteration ; in the Chinese specimens this spot seems always to be developed. The 

 marginal spots of the hindwings are in the Chinese examples on an average larger 

 than in the Japanese ones. One of my Kiu-Kiang individuals exhibits on the 

 hindwings above, besides the anal ocellus and six submarginal lunules, three discal 

 spots situated between the lower median branch and the lower discoidal vein. 



Further researches will perhai)S prove that the Western Chinese macUenlus 

 represent a geographical race. Obeitliiir's figure of scaevohi fits be.st to smaller 

 Japanese individuals.
