found in the female of K. Icnyvettii , de Niceville, from Bhutan, which is 
a closely allied species. Occurs at higher elevations than K. luxtoni , 
Moore, from Bekantschan to the mountains which surround the Central 
Plateau in April and 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 B. pratipa. Whether it should be known by the 
older names of D. bisaltide or I). 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 figure. 
The Himalayan, Assamese, Burman, 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 
Bekantschan, 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 the males. The latter are especially partial 
to settling on old wood, and are commonly found resting.on or flying round 
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 ( JEulepis ) 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 G. hadenii , Felder, this is the most beautiful species of Gharaxes 
found in Sumatra. It occurs from near the sea to the elevation of Be¬ 
kantschan, but not higher. Though it is met with everywhere over a large 
area it is never as plentiful as are G. dolon , Westwood, and G. eudamippus y 
Doubleday, in Sikhim in the beds of streams in the spring. As the
