towards tip ; whole surface with close, short, yellow pubescence. 

 Venter similar, pubescence very short. Leys brownish yellow, a 

 dark brown ring on apical half of hind tibiae ; tarsi tips black. 

 The legs are minutely yellow pubescent, the colour brightest on 

 the tarsi. Wings pale yellow, veins brownish ; a stigma-like oval 

 black spot towards tip of upper basal cell ; the end of the wing 

 mainly occupied by a brovvu suffusion which dies away towards

Described from a single c? in good condition in the Indian 

 Museum collection from Margherita, Assam. 



The abdomen is much shorter and more rounded than in 

 E. marginata, which makes me doubtful whether it is well placed 

 in Eudmetd.
