Crambus bidens Grote, Can. Ent., Vol. XII., p. 77 (1880). 



Expanse of wings, 18 mm. Head and thorax lustrous 

 ochre-yellow ; palpi acute, ochre-yellow. Fore wings bright 

 ochre-yellow, with a few rust-brown scales. A few light 

 patches on the inner margin. A very broad silvery-white 

 stripe extends to the costa on one-half the length of the 

 wing, then turns obliquely in a straight line. On the inner 

 side it sends out an acute tooth, then runs in a straight line 

 and meets the costal line at an acute point near the angle 

 of the subterminal line. This line runs obliquely for one- 

 third of its length, then, forming an obtuse angle, runs in a 

 straight line an equal distance, where it forms a very blunt 

 tooth and continues to the inner margin. On the costa a 

 white spot on each side of the subterminal line ; also one 

 below the brown apex, and a larger one enclosing five dark- 

 brown dots in the terminal space. Hind wings white, slightly 

 dusted with ochreous. 



Habitat. Massachusetts, New York. Early stages and 

 food plants unknown.
