 Hind wing more or less bright-yellow. Abdomen rather slender, the

 finger-shaped, curved and smooth. Uncus long, narrow, and slightly 

 curved, apex with a short beak.

 out cornuti. Penis sheath bearing some short spines at its upper end. 



3. Trisuloides glauca Hampson.

 breadth, not elongate, the cell almost or about three-fifths length 

 of wing. Hind wing typically greyish-brown. Abdomen moderately
