The moths belonging to this genus and its allies arc rather 

 small, with long slender bodies, oblong fore-wings, and rounded 

 hind-wings, with sharply-defined white, brown, and yellowish 

 markings. They are called " China Marks " by collectors. 

 The larvae, which are rather stout, with a small retractile head, 

 feed on water-lilies, and live under the leaves in a case 

 comi)osed of two pieces of leaf.
