of as pure a white colour as in tavoyanns. lu a Kiiia Balu example of heu-itsoni 

 these spots, though feeble, are also visible. Thus I cannot see how to draw a distinct 

 parting line between slateri, tavoyanns, perses, and hewitsoni, and must accordingly 

 treat these insects as subspecies of the same species. 



(a): P. slateri Hew., forma typ. [J,?]- 



The bluish streaks of the forewings are above sometimes of a violet colour; below 

 they are always very faint. The submarginal white spots of tlie hindwing.s are, on 

 the underside, always more or less marked, but faint, seldom as large as in tavoyanus. 

 Female a little larger than the male, otherwise scarcely different.

Oberthiir's marginata stands in the markings of the forewings intermediate 

 between typical slateri and typical tavoyanus ; specimens from the .'iiamese Shan 

 States in my collection agree with Oberthiir's figure, others from the same locality 

 are typical tavoyanus; Tnarginata is, therefore, not a geographical form, and is best 

 treated as a synonym.

This insect has been discovered in the same district where jie?'ses was obtained, 

 and it is most probably nothing but an atavistic example of the latter, provided it 

 has the same structural characters as P. slateri. I have not had the opportunity to 

 examine a specimen of this aberration.
