1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 471 
430. Curetis ^sopus, Fabricius. 
Originally described from the East Indies. 
431. Curetis felderi, Distant. 
Originally described from Province Wellesley and Sungei Ujong in 
the Malay Peninsula. 
432. Curetis sperthis, Felder. 
Hagen. Originally described from Malacca. We have followed 
Mr. Distant’s identifications of these four species, as we have specimens 
from Sumatra which agree with his descriptions and figures of them. 
Whether they are all distinct, or how many of them are so, we are not 
prepared to say. The males are far more commonly met with than the 
females ; which latter have the upperside of the wings orange bordered 
with black, never with the orange colour replaced by white, the more 
usual form of the Indian species. 
433. Curetis insularis, Horsfield. 
A well marked, easily identified, and probably valid species origi¬ 
nally described from Java. 
434. ^Curetis bulis, Doubleday and Hewitson. 
Snellen. Typically not met with by us in Sumatra. 
435. *Curetis barsine, Felder. 
Hagen. Originally described from Amboina. Hot met with by us 
in Sumatra. All species of Curetis in Sumatra occur at low elevations 
with the exception of C. malayica , Felder, which is found in the moun¬ 
tains as well as in the plains. The males usually rest with closed 
wings on leaves near small streams, never fly for long distances, and 
do not go down to wet spots on roads very often, though the males are 
sometimes so found. The females are occasionally only caught in the 
forest. Their flight is so rapid that they can hardly be followed with 
the eye, but if they settle on the upperside of a leaf with closed wings 
their silvery-coloured underside at once betrays them, but if the}’ are 
frightened they settle on the underside of the leaves, where they are of 
course invisible.
