Stout's Hardwood Borer
Polycaon stoutii
Polycaon stoutii, the black polycaon or Stout's branch borer, is a species of woodboring beetle in the Bostrichidae family. It is found in North America in British Columbia, the Pacific Coast states, and Arizona, but has spread elsewhere due to the shipping of wood products.

Description
Adults are 10-23 mm in length. They are cylindrical, hairy, and black. Their heads are slightly downturned. Polycaon stoutii can be distinguished from the related P. granulatus by the antennae having 11 segments and the 2nd and 3rd tarsal segments being cylindrical. It can be distinguished from P. punctatus by its black colouration and the 3rd antennal segment being much shorter than the 4th.
