Note. — lu my opinion P. nomius Esp. was originally a South- West Indian form 

 of F. aristeua Cram., and now lias spread over Bengal, Burma, Tonkin, to South-East 

 China. In Ceylon and West India it occurs alone ; in North India it comes occa- 

 sionally together with P. aristeus miticraies Doubl. ; in Burma and Tonkin it flies 

 together with P. uristeus hcrmocrates Feld. While the white colour of the wings is 

 much extended in the North Indian P. aristeus anticrcUes, the bands remain almost 

 the same in nomius from every locality ; further, while the Burmese and Hainan 

 nomius exhibit an additional black basal line on the underside of the hindwings (see 

 above, simnhoei), which the Bengalese, South-West Indian, and Ceylonese nomiios 

 have not got, the Burmese hermocrates are all devoid of this line. If nomius really 

 be the same species as aristeus, i.e. only an aberration of the latter, it can hardly be 

 explained how the North Indian aristeus has acquired a character which the North 

 Indian nomius does not exhibit, and how it comes that the Burmese aristeus is 

 dex'oid of a character which is found in all Burmese specimens of nomius. I believe, 

 therefore, that nomius is so fixed a form that it does not mix with aristeus, and has 

 accordingly to be treated as a distinct species. — K. J.

Female undescribed. 



Forewings with .six greenish white bands instead of seven, as in /'. aristeus Cram. ; 

 Prof. Eimer (I.e.) lays so much stress upon this character that he separates P. rhesus 

 entirely from the aris/eus-group. The fourth and broadest white liand (counted from 

 the base of the wing) bears, however, not seldom a black spot behind the costal 

 margin, and this black spot has in one of my examples (and in another in -\Ir. Ph. 

 Crowley's collection) developed into a black line, extending from the costal margin 

 to near the median nervure, and dividing the intra- and antecellnlar jiortion of the 

 white band into two bands ; this specimen is thus provided with seven white bands 

 in the costal region of the forewings, and comes indeed very near certain examples of 

 P. aristeus hermocrates Feld. As P. rhesus is also vei-y close to P. aristeus Cram, in 

 the pattern of the hindwings, and is identical in neuration with that species, there is 

 no reason to follow Prof. Eimer.
