 mark on base of dorsum ; moderate fasciae at ^ and beyond middle, 

 rather dilated towards dorsum, anterior edge of each straight, 

 posterior sinuate; a white dot on costa at |, whence a sinuate row 

 of black scales crosses wing; a triangular spot on costa towards 

 a])ex, almost touching termen ; an apical dot : cilia grey, round

Brngal, Pusa, bred in August from larva mining blotch in leaf 

 of l/iomoea batatas (Conrolvulacece) (Fletcher). Near caiheclraea . 



Acrocercops supplex, n. sp.

Bengal, Pusa, bred in August from larvae mining blotches in 

 leaves of TermhiaJia cata/>iia (Combretacece), in company with 

 A. erioplaca and undistinguished from them (Fletcher); the species 

 are however abundantly distinct. Two other species of Acrocercops 

 also feed similarly on the same tree, ierminaliae Staint., which 1 

 possess, and diffludla J)ev., which as yet is only known from Java, 

 and is verv different.
