js^oTf prominent than above, with an additional minute oval 

 sp^o; in the upper subcostal interspace. Body concolorous with the

 above black faintly annulated with white, beneath entirely white ;

Nearest to A. savitri, Felder, described from the Malay Peninsula, 

 recorded by Mr. Distant from Province Wellesley, Malacca, Ayer 

 Panas, and Singapore, all in the Malay Peninsula, and from Borneo ; 

 in my collection from Rawan and Perak in the Malay Peninsula, North- 

 East Sumatra and South-East Borneo, which is the same species as 

 A. susa, Hewitson, described from c ' India," from which it differs in 

 the ground-colour being a rich chestnut instead of ochreous-brown ; 

 the discal bands are more prominent and whiter, that on the 

 hindwing with a regularly curved even inner edge, in A. savitri the 

 inner edge of the band is very irregular ; and, most important of 

 all, the tail in A. savitri is long and pure white, in A. atlas it is short, 

 ferruginous, and just tipped with white only. 



Described from three males and one female kindly sent to me by 

 Mr. H. Fruhstorfer from Java, but without precise locality.
