Differs from myrrhina in the whole basal half of the fore wing 

 beiDg metallic green, sometimes with a bronzy tint, and with black 

 marks before the pale band ; black streaks in the interspaces of 

 the apical area. Hind wing with the apex black shot with blue.

Differs from affinis in the basal area of the fore wing being 

 golden green, traversed by an orange band bordered by bine-black 

 on each side, this basal area terminating in a blue-black edge ; the 

 subapical spots obsolete. Hind wing with a larger apical blue- 

 black patch. 



The hind wing is sometimes pure white.

Differs from affinis in being bluer. The fore wing may have 

 the basal area entirely blue-green with black spots, or there may 

 be a large white or pale yellow patch below the ceil and along the 

 inner margin ; the median band is white or pale yellow, and broad 

 and irregular, or reduced to a series of irregularly placed spots ; 

 the veins of the apical area are more narrowly green than in affinis ; 

 the subapical spots are sometimes prominent, sometimes completely 

 obsolete. Hind wing white or pale yellow, with a black irregidar 

 marginal border shot with blue, which colour sometimes extends up 

 below the cell to the base, reducing the white area to a patch 

 beyond the cell ; sometimes the blue-black colour is entirely 

 wanting, except for a small subapical spot, and all the intermedial e 

 stages seem to occur irrespective of locality. 



Pectinicornis is the darkest form, with the base of fore wing
