Peradeniya, Ceylon ; twenty specimens (Green). Larva mines in young 

 leaves of ebony, Diospyros emblyopleris (Green). Owing to the extreme 

 slenderness and delicacy of the wings the neuration proved very difficult to 

 ascertain, but in a denuded specimen the forewing appeared to be as follows : 

 \b simple, 2 from f, 4 and 5 approximated from angle, 6 and 8 long-stalked, 6 to 

 termen, 7 absent, 9 and 10 from near 8, 11 absent.
