1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 439 



butterfly have recently been defined, P. belisama, Crowley, from Tonghou, 

 Central Burma, and P. chrysodonia, Staudinger, from Davao, S.-E. 

 Mindanao, in the Philippine Isles. In Sumatra P. calydonia is found 

 only in forest from Selesseh to Bekantscban and higher, and is rare as it 

 always is everywhere. Dr. Martin took his first specimen, the first 

 known from Sumatra, in October, 1888, near Kampong Roemah 

 Kenangkong on a wounded tree where it was sucking up the juice. 

 Siuce then he has obtained eight other specimens. As above mentioned 

 (p. 420, n. 202), there may be found over a large area of forest only one 

 pair of this strong- winged butterfly, which likes to keep to the higher 

 trees, quite out of the reach of the net, but is fond of faeces and strong 

 smelling things such as carrion, to which it is often attracted and caught. 

 From Wallace's account of the capture of the type specimen of the species 

 at Ayer-panas in Malacca it is known how closely this insect keeps to one 

 place, even to the same tree. It was on the fourth day, after having 

 missed it the three previous days, and on the very same tree, that 

 Dr. Friedl Martin caught his first specimen at Aer Kesoengei in Asahan. 

 P. calydonia settles with the head downwards on tree trunks, and 

 makes while feeding the same rotating movements of the hindwings as 

 is done by many Lyccenidai. 



267. Prothoe angelica, Butler. 



Grose Smith as franckii. Hagen as frankii [sic], Godardt [sic], 

 Wallace as franckii. Distant. Semper. The true P. franckii, Godart, 

 is confined to Java. Occurs in Sumatra in the same localities and 

 elevations as P. calydonia, Hewitson, but is not so rare; settles also on 

 tree trunks with its head downwards. 



Family LEMONIID^E. 

 Subfamily Libythjiinj;. 



268. Libythea myrrha, Godart. 



Hagen as myrrha, Godardt [sic]. Found in forest from Selesseh 

 to Soengei Batoe, and is not very common. It is fond of settling with 

 folded wings on wet sand on the banks of small streams. 



269. Libythea narina, Godart. 



The L. rohini of Marshall is a synonym of this species. Occurs in 

 Sumatra near to the sea, as Dr. Martin obtained his first specimen near 

 Kamborg-house between the Saentis and Mabar Estates in May, 1890. 

 Found also at Selesseh, but does not extend higher than Namoe Oekor 

 and is very rare.
