Hah. Rio de Janeiro: Cantagallo; Bahia. 



One specimen in the British Museum was taken by the 

 late Mr. A. Fry at Cantagallo, and Herr Felsche possesses 

 two examples from Bahia. 



It is a large, strongly-built species, and distinguished, 

 in addition to its colour, by its short and flattened posterior 

 tibiae and not excessively long tarsi. The elytra are more 

 strongly punctured, more rounded at the sides and more 

 tapered behind than in A. hrunneus, Er., the clypeus is 

 larger and rather rectangular, with a broad thickened 

 margin, and the labrum is broad and has a similarly 

 thickened anterior margin.
