 A large handsome species resembling A. auratum, Pasc, but 

 differing from it inter alia in the less emarginate base of the 

 prothorax, and in the elytral sculpture, — consisting of rows of 

 unevenly placed round foveee which are connected one with 

 another longitudinally by series of much finer punctures. The 

 strongly thickened lateral edges of the prothorax distinguish the 

 present insect from most of its congeners.
