found in the female of K. knyvettii, de Niceville, from Bhutan, -winch is 

 a closely allied species. Occurs at higher elevations than K. buxtoni, 

 Moore, from Bekautschan to the mountains which surround the Central 

 Plateau in April aud July ; is also rarer than the yellow species. Both 

 are found only in large forest. 



252. Doleschallia pratipa, Felder. 



Snellen as bisaltide. Hagen as bisaltide and pratipa. Distant 

 doubtfully from Sumatra as bisaltide. The Sumatran form agrees 

 exactly with the one from the Malay Peninsula which has been des- 

 cribed by Felder as D. pratipa. Whether it should be known by the 

 older names of D. bisaltide or D. polibete, both of Cramer, I am not 

 prepared to say, as several of the species of this genus are so variable 

 that to define their limits seems the more difficult the greater number 

 of specimens one obtains, more especially as the variations do not appear 

 to be confined to geographical areas. The female of the Sumatran form 

 agrees very fairly with Cramer's figures C and D of pi. cii of Pap. 

 Ex., which also appears to have been taken from a female, and is named 

 " Papilio " bisaltide from " Surinam," a probable lapsus calami for 

 Sumatra. But I have no specimen agreeing exactly with that fig-ure. 

 The Himalayan, Assamese, Barman, South Indian, Ceylonese, Anda- 

 manese and Nicobarese form is fairly constant, and is usually identified 

 as D. polibete, originally described from Amboina. Hagen records two 

 species of the genus from Sumatra, but this is almost certainly incorrect. 

 D. pratipa in Sumatra flies from near the sea to the elevation of 

 Bekautschan, but not higher, and is found in forests and also near 

 houses which are surrounded by fruit trees and small jungle. The 

 females are much rarer than tbe males. The latter are especially partial 

 to settling on old wcod, and are commonly found resting on or flying ronnd 

 wooden bridges on forest roads. Dr. Martin has frequently noticed 

 them resting on wooden bullock carts left on jungle roads, to which they 

 return again and again if disturbed. Dr. Hagen bred it at Laboean 

 the larva feeding on the Jack-tree (Artocarpus integrifolia, Linnaeus). 



253. Charaxes (Eulepis) delphis, Doubleday. 



Hagen. Kirby as concha. The G. concha of Vollenhoven was des- 

 cribed from Padang, Sumatra, and is a synonym of this species. Next 

 to 0. hadenii, Felder, this is the most beautiful species of Charaxes 

 found in Sumatra. It occurs from near the sea to the elevation of Be- 

 kautschan, but not higher. Though it is met with every w T h ere over a laro-e 

 area it is never as plentiful as are G. dolon, Westwood, and G. eudamippus 

 Doubleday, in Sikhim in the beds of streams in the sprino-. As the
