Habitat in Java, Singapore, etc. 



The costal vein of the fore wings in this species apparently 

 extends into the pale submarginal fascia, emitting two branches to 

 the costa, the first of which is, in fact, the real termination of the 

 costal vein ; the second, as well as the apparent termination of the 

 costal, being the extremities of the first and second branches of the 

 subcostal vein, of which the third and fourth branches are free. 



The under surface of the wings varies considerably in the in- 

 tensity of the markings, especially in specimens from Singapore, 

 from whence it has been sent by Mr. Wallace. The male has a 

 patch of hairs at the base of the hind wings on the upper side. 



In its colours there is no difference between the sexes of this 

 species.

Above all the wings fuscous black, the anterior with a broad 



band-like spot, commencing near the costa beyond the middle, 



and extending towards the anal as far as the lowest median ner- 



vule. This spot is of a brilliant metallic changeable blue, much 



paler and less changeable externally. On the posterior wings is 



a large patch of the same rich blue, paler in the centre, occupying 



the whole disc of the wing. Below, all the wings less black than 



above, the outer margin paler ; this pale portion bounded internally 



by an undulated pale or whitish striga, becoming brown towards 



its termination at the anal angle of the posterior wings ; between
