Attagenus sopitus sp. nov. 

 PI. IX, %. 10. 



A rather poorly preserved specimen, showing the prothorax and most 

 of the elyti-a, seems to belong here. It is of about the size of A. pellio L. 

 The prothorax, from which the head can not be separated, is triangular with 

 rounded angles, the middle of the hind margin produced but rounded 

 apically, the whole surface feebly punctate, but with larger puncta than in 

 A. megatoma Fabr. Elytra shaped much as in A. 2}eUio, with well-rounded 

 humeral angles, but proportionally slightly longer than in the modern species 

 and more coarsely punctate. 



Length of body, 4.5 mm.; breadth, 2 mm.
