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 Peniusnla. 



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 npperside 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 bcjlis, Doubleday and Hewitson. 

 Snellen. Typically not met with by us in Sumatra. 



435. *Curetis barsine, Felder. 



Hagen. Originally described from Amboina. Not met with by us 

 in Sumatra. All species of Curetis in Sumatra occur at low elevations 

 with the exception of G. malayica, Felder, which is found in the moun- 

 tains as well as in the plains.. The males usually rest with closed 

 w T ings on leaves near small streams, never fly for long distances, and 

 do not go down to wet spots on roa is very often, though the males are 

 sometimes so found. The females are occasionally only cauo-ht 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 wino-.s 

 their silvery-coloured underside at once betrays them, but if thev are 

 frightened they settle on the underside of the leaves, where they are of 

 course invisible.
