GROUP I. (NENUPHAR GROUP.) 



The species of this group have the costfp of the third and fifth 

 intervals of elytra usually more or less interrupted in two places; 

 thorax strongly constricted near tip; pubescence short, fine and 

 appressed, usually forming one or more slender pale oblique lines 

 each side of thorax and a broad band behind the middle of elytra.
