Charaxes, pt., Ochsenheimer, Schmett. Eur. iv, 1816, p. 18 ; Felder, 



Ein Neues Lep. 1861, p. 39 ; tie N. Butt. Lid. ii, 1886, p. 269. 

 Eulepis, Moore, Lep. Ceyl. i, 1880, p. 29. 



Type, E. atliamas, Drury, from India. 



Range. Indo-Malayan Region. 



S $ • Closely allied to Charaxes, but can at once be distin- 

 guished by the cell of the hind wing being entirely open. Other 

 minor points of difference are " the costal edge of the fore wing is 

 never so highly specialized as in the large species of Charaxes " 

 (Rothschild &f Jordan) ; the colour-pattern is absolutely different ; 

 and there are considerable differences in the genitalia, the Eulepis 

 group having the genitalia more uniform, Charaxes more variable.
