towards and away from each other with very little " skip " up and 

 down, though there may be much deviation to either side from the 

 straight course. The butterflies are rather pugnacious amongst 

 themselves, pursuing each other on the wing with great vigour and 

 determination. The food-plants are, as far as is known, all belong- 

 ing to the same genus, Flacourtia (Bixinece) ; the two species the 

 caterpillar has been found on are F. ramontchi, L'Herit. and F. mon- 

 tana, Grah., both common in the Western Ghats, the former spread 

 throughout Continental India. The insect is found also nearly 

 throughout Continental India, in Ceylon, Assam, Burma and 

 Tenasserim, extending to China, Japan and the Malayan Sub- 

 region. The Assamese species of the food-plant, Flacourtia 

 catajjhracta, Roxb., extends to China and the Malay Islands and 

 probably Japan. 



There is another species of Atella, occurring very locally in the 

 District of North Kanara, which has been obtained lately in 

 Travancore and is known from Ceylon ; it exists also in Sikhim, 

 Assam, Cachar, Arrakan, Burma, and extends into the Malayan 

 Sub-region. No specimen has ever been got from any part of 

 India between Assam and Kanara, nor from anywhere on the East 

 Coast. The larva is very like that of A. flialantlia ; so is the pupa. 

 The food-plant is Alsodeia zeylanica, Thwaites, belonging to the 

 Violacece, a family of plants nearly allied to Bixinece and containing 

 most of the food-plants of the Fritillaries (genus Argynnis) at home 

 in Europe, which are not far removed from our genus Atella. 

 Alsodeia zeylanica is known to exist in Malabar and Cochin and 

 Ceylon but was unknown in Kanara until the caterpillars of the 

 butterfly were discovered ; and the plant is as locally distributed 

 there as the insect. The name of this interesting species is Atella 

 alcippe, Cramer.
