wings in the male, thereby agreeing with O. Iambi, Distant, from the 

 Malay Peninsula and Nias, and G. cayaya, Felder, from the Philippines. 

 I cannot, however, regard G. Iambi as anything but a synonym of 

 G. puspa, that species being very variable, and in the Himalayas em- 

 bracing a form inseparable from G. Iambi. G. cugaya, Felder, as figured, 

 has the black bordtfr to both wings on the upperside somewhat narrower 

 than in Javau specimens of 0. puspa, from whence it was first described. 



329. Ctaniris carna, de Niceville. 



C. carna, de NiceVille, Journ. Bomb. Nat. Hist. Soo., vol. ix, p. 274, n. 11, pi. 0, 

 fig. 18, male (1895). 



The rarest of all the Sumatran species of the genus. " The infus- 

 cation of the eosta and apex of the forewing on the underside " is not 

 always present, but the other characters given in the description will 

 suffice to distinguish this species from its allies.

C musina, de Niceville, Journ. Bomb. Nat. Hist. Soc, voL ix, p. 275, n. 12, pi. O, 

 fig. 19, male (1895). 



A very common species in Sumatra. I have not been able to obtaiu 

 typical specimens of this species from Java to compare with Sumatran 

 exampleu. 



331. Ctaniris pi,acida, de Niceville. 

 Not Yerj common in Sumatra. 



332. Ctaniris camen^e, de Niceville. 



C. camense, de NiceVille, Journ. Bomb. Nat. Hist. Soo., vol. ix, p. 278, n. 14, pi. O, 

 fig. 22, male (1895). 



The commonest species of the genus occurring in Sumatra. 



333. Ctaniris limbatus, Moore. 

 Also common. 



334. Ctaniris mel-ena, Doherty. 



Originally described from the Tenasserim Valley, Burma. Very 

 rare in Sumatra, Dr. Martin has obtained two or three specimens only 

 in the Battak mountains. Of the ten Sumatran species of Cyaniris, 

 only two occur in the plains, G. cosssea, de Niceville, and C. puspa, 

 Horsfield, all the others are found in the mountains at high elevations 

 from Soengei Batoe to the Central Plateau, and on the Plateau itself. 

 C. akasa, Horsfield, and C. cor y thus, de Niceville, are somewhat scarce,
