 tioned bv Hampson in his * Moths of India.* 



In Cat. Het. Mus. Oxon. ii. p. 165 (1900) I put Phagytra 

 leucogastralis, Walker, xxxiv. 1508, type from Java in B.M., 

 = Metria lAatijpoda, Felder, Keise Nov., Lep. pi. 120. f. 44 

 (1873), type Amboina, in Coll. Rothschild, as a synonym to 

 the above ; but in this I think I was wrong : leucogastralis
