Mr. Trimen appears to me to have been unfortunate in defining 

 the distinctive characters between this form and J. orithyia ; so far 

 as 1 can judge, he must have had either the Malayan J. wallacei or 

 the Javan J. ocyale before him when making his comparison. The 

 width of the subapical bar on the primaries is very variable ; indeed 

 it varies quite one third in the three examples above enumerated : 

 the adjacent yellow markings also vary not a little ; the black streak 

 intersecting the lower part of the bar between the two ocelli is want- 

 ing in J. uiallacei, slightly indicated in J. ocyale and J. orithyia, 

 rather stronger in the Indian J. switihoei, still stronger in the Aus- 

 tralian J. albicincta, strongest in J. here and J. boopis, but it is not 

 absolutely constant ; the blue of the hind wings is sliglitly more re- 

 stricted than in any of the other forms, and this is, I think, a reliable 

 character, but the tint is variable in all the forms, and therefore is 

 valueless as a distinctive character ; the colour of the white spots is 

 also untrustworthy, but the border of the secondaries in all our 

 specimens is greyish, especially in male examples, hardly a trace of 

 white appearing between the black lines in specimens of this sex ; 

 indeed, the hind marginal striae hardly merit the term " whitish " 

 used in Mr. Trimen's description. The example figured on his plate 

 seems unusually large for a male, and the form of its primaries is 

 that of a female ; but for Mr. Trimen's declaration that it is a male, 

 I should have suspected it to be hermaphrodite. The colouring of 

 the under surface in typical J. orithyia, from China, is browner 

 (more argillaceous, in fact) than in any of the allied forms. I would 

 therefore define J. boopis as differing from /. orithyia in the four 

 following characters : — 



1. Subapical white bar of primaries, always in the male and
