black vein ; spot M' — IP the largest, either oblong or proximally narrowed, being 



reduced behind. Hiudwing : band rather more rosy than in eri/tJirus, mnch 



narrower than the brown-black distal area, not entering cell, almost straight, 

 extending from abdominal edge to R^ or a little beyond. 



U7iderside : white patches sometimes larger than above, and band of hindwing 

 paler, usually consisting of four spots R- — (SM'), the abdominal spot (SM')— SM^ 

 being rarely present ; some specimens with a minute dot before W.

(?. Upperside. — Forewing : green patch strongly narrowing discally, rarely 

 extending forward a little beyond M' ; a rather large rounded creamy white spot 

 M' — M'-, often followed by a second spot and not rarely preceded by a third, the 



■white spots being seldom missing. Hindwing : three, seldom two, small red 



spots, sometimes a vestige of a fourth spot behind M^. 



UndiTsidi' : forewing always with two or three white spots, one of tliem 



usually grc) or vestigial. Hindwing usually with five spots, the central discal 



ones often touching cell ; the spot on abdominal fold sometimes absent, a few 

 specimens bearing a sixth spot before R^. 



?. AVe are not sure that the female figured by Gray really belongs to this 

 species. We have several specimens agreeing fairly well with the figure. The 

 second discal spot of the forewing larger than the first, as is the case also in
