in curons ; only the black bands are rather broader ; the dark outer 

 marginal band is broader and does not stop at third median nervale 

 but is continued to outer angle. The female agrees better with the 

 figure given by Leech than the male. In the female and one of the 

 males the fifth band from the base crossing the cell before apex is 

 interrupted in the centre. 



Hindwing-upperside. The black discal and inner bands forming 

 a V of the yellow ground colour have not such irregular edges as in 

 eurous, are broader and more vertical in relation to costa, the faint 

 line (exterior to discal band), which is reproduced from the under- 

 side and ends at median nervure, straighter and not with such irregular 

 edge ; the first and second median nervular interspaces are more suf- 

 fused with fuscous and are divided by a black' spur which joins the 

 discal band at the median nervule reducing the yellow expanse of 

 these interspaces ; submarginal black band more oblique, broader and 

 suffused centrally with fuscous, edge of outer line of band not so 

 irregular ; space between submarginal band and marginal black line 

 much suffused with fuscous ; tails rather longer being 1 5 millimetres 

 against 80- millimetres in Leech's figure of citrous. 



Underside-hindwing. Upper part of double lines of discal band 

 not so chain like as in citrons, outer line of discal band interrupted at 

 median nervure as in citrons and between first and second median 

 nervules, but continued from second to third median nervules, dividing 

 upper yellow space of second median interspace diagonally into two. 



Expanse. Two males, 82 to 86 millimetres ; female 83 millimetres. 

 Female. The female does not differ from the male in markings but 

 only as regards shape of forewings which are more rounded at apex 

 and costal margin. 



Distribution. Central China (Chang-yang) ; Moupin ; Formosa.
