In some examples of the ? of this species, the 

 phylliform green marks of the anterior wings become in 

 certain lights much more golden green than in the figs, on 

 pi. 26 ; and portions of the posterior wings become vivid 

 golden, with no admixture of green. The right wings may 

 also be held in such a position as to render all the markings 

 an ashy-silvery purplish-green. 



? In other examples all the green markings are less 

 broadly formed, and are entirely greenish-golden, with 

 a faint bluish tint near the base of the posterior wings. 

 The colour marks of the disc on the under side of 

 the anterior wings are a vivid silky greenish gold — 

 the lowest or submedian being ultramarine blue at the 

 basal end ; a small golden patch, shading into blue, 

 occupies a position midway between the base and the 



distal end of the cell. On the underside of the posterior 

 wings is a submedian band of blue atoms following the 

 curves of the vein, but becoming very slight towards the 

 anterior angle ; a small group of blue atoms is also found 

 at the base beyond the precostal nervure. 



Additional localities : Sandakan, North Borneo ; Malay 

 Peninsular ; also on Balabac Island, one of the Naturna 

 group. The variety albescens of Rothschild, which Mr. 

 Rothschild quotes as a sub-species, is found in Malacca. 



It may be added that the ? 2 from the Malay 

 Peninsula always differ from those of other localities.
