Genus LADE. 



Lade, de Niccville, Jour. Bomb. N. H. Soc. xii, 1898, p. 153 ; Moore, 

 Lcp. Ind. vii, 1905, p. i. 



Type, L. lalassis, Grose-Smith. 



Range. Burma and Malay Peninsula. 



c? $ . Closely resembles the genus Appias, but in the fore wing 

 the costa is more convex, the apex strongly curved downwards*, 

 falcate. Venation very similar to, almost the same as in Appias. 

 Antennae with the club proportionately longer and narrower. 

 Abdomen <3 : the anal tufts of hair so conspicuous in Appias J 

 entirely absent. 



So far as is known at present this genus is monotypic, and 

 is found only in Burma and the Malay Peninsula. In general 

 appearance L. lalassis, Grose-Smith, very closely resembles the 

 dry-season forms of Appias lalftge, Doubleday^ which also has a 

 more or less falcate fore wing and very similar markings.
