It is distinguisned from A. fcetidus by its slighter con- 

 vexity, darker elytra, distinct frontal tubercles (in the male), 

 less closely punctured thorax, and the more strongly punc- 

 tured striae of its elytra. 



From A. piceus, Gyl. (not as yet correctly recorded as Bri- 

 tish, but likely to occur here), it may be known by the finer 

 and more equal punctuation, and less blunt hinder angles of 

 its thorax ; also by the somewhat finer striae of the elytra, 

 and the armature of the head, inasmuch as in both sexes the 

 transverse line on the clypeus is distinct, and the middle 

 tubercle in the male is not stronger than those on its 

 sides.
