rich dark iridescent ultramarine-blue instead of " dull indigo-blue," 

 and the marginal spots of the hindwing on the underside larger and 

 more intensely black. The two species are abundantly distinct, the 

 coloration of the upperside alone will instantly distinguish between them, 

 besides many small differences in the details of the markings. The 

 figure of C. merguia is not very good, the underside is mostly " pearl- 

 grey," it is shown of a dull ochreous tint almost throughout. 



Described from a single example (the specimen described and 

 figured) from Java without precise locality, kindly sent to me by 

 Mr. H. Fruhstorfer, and another male from N.-E. Sumatra sent to 

 me by Hofrath Dr. L. Martin, who has other examples in his own 

 collection. He informs me that he has recently described this species, 

 but the description has not as yet reached me. However, I have 

 adopted his name for it.
