elytra universally and profoundly punctured; margin a 
little reflexed ; apex obtuse ; legs reddish-piceous : thighs 
nearly equal : tarsi slender, penultimate joint not bi-lobate. 
Length less than four tenths of an inch. 
A remarkable species and recedes from the CEdemer-

genus by itself, as the connecting link between Dytilus 
and CEdemera.
