A. stolidum, Germ. This species is very closely allied to the pre- 

 ceding, and has by many authors been considered merely a variety ; it 

 may, however, be known by the stronger striae of the elytra and con- 

 sequently narrower interstices ; the rostrum is a little longer and more 

 curved, the frontal impression is stronger, and the thorax is broader; the 

 general form is said to be shorter, but intermediate specimens occur ; the 

 pubescence also is less evident. L. 1^-lf mm.
