Leptosia^ pt. Hiibner, Verz. bek. Schmett. p. 95 (1816) ; West 

 wood, Butterflies of Great Britain, p. 28 (1855); Butler 

 Cist. Ent. i. pp. 39, 54 (1870)- 



Leucophasia^ Stephens, 111. Brit. Ent. Haust. i. p. 24 (1827); 

 Boisduval, Spec. Gen. Lepid. i. p. 428 (1836); Double- 

 day, Gen. Diurn. Eepid. p. 38 (1847); Schatz, Exot. 

 Schmett. ii. p. 57 (1SS6). 



Leptoria^ Westwood, Brit. Butterflies, p. 41 (1841). 



Cells of the whigs very short ; sub-costal nervure five- 

 branched, all the branches emitted beyond the end of the 

 cell ; first discoidal nervule emitted from the end of the cell ; 

 antennas short, slender, with a well-marked flattened club. 



Wings narrow, elongate-oval, thickly clothed with scales. 



This genus only includes a few species, much resembling 

 each other, and is confined to Europe and Northern and 

 Western Asia. It has a slight superficial resemblance to the 

 African and Indian genus to which Dr. Scudder correctly re- 

 stricts the name Leptosia^ but this has much broader, shorter, 

 and rounder wings.
