AMBLTPODIA GROUP OP THE LYC^NID^E. 107 



This species may at once be recognised from the preceding by its very much 

 smaller size, by its brassy-green colour, and by the quite different pattern of the 

 underside. 



The female is, I believe, entirely unknown. It is apparently a rare species, being 

 either not represented, or, if represented, in most collections it is only by two or three 

 specimens. Mr. Cator brought home from the small island of Sapagaya more specimens 

 of this butterfly than I had seen before in all the collections I had been through, yet 

 there was not a single female among them.

Hab. Borneo (Kina Balu, Tameang-Lajang) ; Malacca. 



Expanse, 3 , 42-46 mm. 



From aurea Hew. this species may be recognised by the deeper tone of the green, 

 by the decidedly paler and more uniform colour of the underside, the pattern being 

 likewise paler, and by the pattern itself. In the primaries the transverse band is 

 straighter and wider, in aurea it is rather sharply angular, whilst in the secondaries 

 this band is decidedly obscure. The female of this species also is at present unknown 

 to me.

Hab. Perak ; Sumatra. 



Expanse, 3 40, $ 37-38 mm. 



This beautiful species may immediately be separated from its near allies by the 

 purple tinge of its underside, and by the large and prominent pattern thereof. Like 

 some others of this green group, it is apparently very local and very rare.

3 . Upperside : both wings dark brown, with a large bronzy metallic-green patch in 

 the primaries from about the costal nervure to the internal margin up to half the 

 median area, but ending abruptly at the close of the cell ; in the secondaries this 

 metallic patch is very small and does not much exceed the cell itself ; tail brown, white- 

 tipped. Underside : both wings brown, very slightly lustrous, with dark spots palely
