 stouter build and shorter antennaj. Head black, narrower before the eyes, but 

 with sides parallel, about as broad as long, puncturation urabilicate as in ^. 

 uniformis. Antennae reddish-testaceous, shorter than in A. uniformis, the indi- 

 vidual joints being shorter. Thorax black, about as broad as long, widest in 

 front, gradually narrowed behind, anterior and posterior angles obtusely 

 rounded, each bearing a seta ; puncturation of similar character to that of head, 

 but rather coarser ; pubescence yellowish. Elytra longer than broad, parallel.
