 the margins very tine: surfnce iniinilely ;in(l r.itlicr sjiMrscly jmuctured. 

 Elytra less than one-halt longer than wide, narrowly rounded at apex, very 

 feebly rugnlose, minutely and sparsely punctate. Length 1.5-2 mm. 



Marion and Dubois counties ; rare. April 4-October 31. 



IV. Ennearthron Meilie. 1847. (Gr., "nine + joints.")

V. Ceracis Meilie. 1848. (Gr., "horn + worm.") 



The members of this genus are very similar to those of Ennear- 

 thron, but the antenna^ are only S-jointed, one of the small joints
