Appears to be common in the mountains of Perak and N.-E. 

 Sumatra, and I have described it from a long suite of specimens in 

 Dr. Martin's and my own collection. 



P. S. — Since the above was written, I have sent all the original 

 drawings of the species of Cyaniris described in this paper to Heer 

 P. C. T. Snellen of Rotterdam, who has done such excellent work in 

 elucidating the Lepidoptera of M alayana. He informs me that the 

 species above described which I had named C. candaules is his 

 " Lyccena " musina, so I have adopted his name for it. Should, how- 

 ever, the species ultimately prove to be distinct (I possess no specimens 

 from Java to compare with my series from the Malay Peninsula and 

 Sumatra), I would propose the name 0. candaules for it.
