1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 295 
111. Thaumantis ( Kringana ) noureddin, Westwood. 
Occurs at the lowest elevations and nearest the sea of all the 
species in the genus, as nearly all specimens obtained by Dr. Martin 
came from Kampong Stabat, and were caught in forests on both sides 
of the Wampoe River. He also obtained one pair as far south as 
Asahan. 
112. Thaumantis ( Kringana ) lucipor, Westwood. 
The commonest of the three Sumatran species of the genus. It 
appears as low down as Bindjei, and is found as high as Namoe Oekor. 
Dr. Martin caught his first specimen of this species, a female, in June, 
1888, at 7-30 p. m., flying along the white walls of his hospital so 
that he could just distinguish it to be a butterfly. In this species the blue 
reflections of the male on the upperside of both wings are so richly bril¬ 
liant and powerful that in opening the wings of a closed specimen the 
pinchers used are strongly coloured with blue like the wings. All Thau - 
mantides are inhabitants of the high virgin forest. They all like shade, 
and are on the wing very late after sunset. All are fond of the ripe 
fallen fruit of the Sumatran sugar-palm ( Areuga saccharifera ) on which 
they regale themselves in the shadow of the tree. They rest with 
closed wings, and only display their rich blue coloration when on the 
wing. 
113. * Tenaris birchi, Distant. 
Originally described from Singapore. Recently taken by Dr. 
Hagen in Mandalieling, a Malay state in Western Sumatra. 
114. Discophora necho, Felder. 
Hagen as necho , Felder, var. cheops , Felder. Staudinger as cheops. 
Semper as cheops. I described this species as I). dis (Journ. Bomb. Nat. 
Hist. Soc., vol. vii, p. 325, n. 3, pi. H, fig. 3, male (1892). D. necho is 
a common species, and is found also in Java and Borneo. Semper 
records D. celinde , Cramer [should be Stoll] as well as D. necho 
from Sumatra. As I), celinde was described from Java where 
JD. necho also occurs undoubtedly, it may be that both D. celinde 
and D. necho occur also in Sumatra. Amathusia phidippus, Joh- 
anssen, is the commonest, and D. necho the next commonest species 
of the subfamily in Sumatra. The males are very fond of fre¬ 
quenting faeces on roads, from which they fly into the jungle 
■when disturbed, but return again as soon as danger is past. The females 
are much rarer, and only fly in the evening after sunset and then only 
very high up in the air, so that they can hardly be distinguished from
