 Genus IPHIAS Bsd. (PL III, fig. 2, a, 6, c, d, e, /.) 



Usually this genus is indicated by the name Hebomoia given to it by 

 HuBNER. This name is indeed the oldest (18 16). But Mr. Snellen does 

 not want to accept it because of the reason mentioned above concerning the 

 genus Thyca. In my opinion, however, the more practical profit of not changing 

 names which are used universally, is of more importance.

This pretty butterfly, whose eyes during life are pale grey, has a high, 

 strong flight and likes to fly on the flowers of trees and shrubs, but often sits 

 down also on wet sand. It occurs in the higher as well as in the lower 

 regions, but is in Java more common in the lower districts, whereas in Sumatra, 

 according to Hagen, the contrary seems to be the case. 



W. J. Batavia (3 — 14), Buitenzorg (265), the Gedeh and Wayang mountains 

 (1500). I received also a pair from Batavia, caught there in the middle of 

 the dry season, the $ of which very fresh ; differences between these and those 

 caught there in the wet season, did not present themselves. 



C. J. Ambarawa (1500), Bojonegoro (258) and in the province of Tegal. 



E. J. Berbek (13), Kediri (64), Klakah (230) and also in Madura. 



The genus to which this butterfly belongs, is confined to the Indo-Australian 

 fauna, in which it occurs from Ceylon to the Moluccas in many varieties of 

 colour, each variety representing a different stage reached in the colour-evolution. 



In how far local separation has already caused different species to arise 

 there, can only be proved from the examination of their sexual organs ; for 

 this reason Fruhstorfer thinks he may accept two species to which all these 

 local varieties should belong. See his essay published in the „ Deutsche 

 Entomologische Zcitschrift Iris (XX s. 89). Much may probably be learned in 

 this respect from the knowledge of the earlier stages, but so far they are 

 known only of one form.
