the South- West Monsoon and at the end of the year. Rothschild 

 restricts this particular form of E. athamas to the Central Provinces of 

 India, South India and Ceylon. The parent form, true E. athamas, he 

 gives from N.-W. India to Southern China, Burma, the Malay Penin- 

 sula, and Indo- China. Its transformations have been frequently re- 

 corded. 



Group Fotamina. 



33. PoTAMis {Bohana) camiba, Moore. 



This species is confined to Ceylon and Southern India, to the north- 

 wards being replaced by P. parysatis, Westwood, that species being 

 found in the Himalayas, Assam, Burma, Indo-China and Southern 

 China. It is w^idely distributed in Ceylon from the low hill country 

 upwards, and the males are not uncommon ; the female, as in the 

 genus generally, is much less commonly seen, and is a good mimic of 

 species of Ergolis. The larva and pupa have been described aud 

 figured. 



Group Euthaliina. 



34. Parthenos ctaneus, Moore. 



Confined to Ceylon, replaced in South India by P. virens, Moore. 

 P. cyaneus is found at all elevations, is not rare, but is difficult to catch. 

 It has a remarkably distinctive mode of flight, which makes it recogniz- 

 able at once on the wing. It flies in May, June and July, and again in 

 November and December. Moore describes and figures its early stages. 



35. Symph^dra nais, Forster. 



Found on the eastern side of the island near Trincomali, and in the 

 grassy country near Haldummule from 600 to 2,000 feet elevation, 

 commonly in November and December. In India it is widely distri- 

 buted. Its larva feeds on JDiospyros, Nat. Order EbenaceaSj and on Sal 

 {Shorea rohusta). 



36. EuTHALiA {Bojphla) evelina, Stoll. 



Restricted to Ceylon, replaced in South India by the closely-allied 

 E. laudahilis, Swinhoe. Common in the jungles in the low country in 

 the North Central Province, probably throughout the year in greater or 

 less abundance. On one occasion Manders counted thirty of these 

 butterflies sucking up the sap flowing from a tree in the jungle near 

 Mahintale in August. It occurs also in the forests near Galle and 

 Labugama. Its transformations are unknown. The larva will probably 

 be found on Diospyros,
