 Ckaudoir has separated this species from the Chlaenius on account of the mentum, al- 

 together exceptional , being transversely trapezoidal, much narrower anteriorly, 

 scarcely at all emarginate in front, the sides very obliquely truncate; without men- 

 tum tooth. See Horn. Trans. Am. Ent. Soc. V, 273.
