H. concolor is sculptured like H. unicolor, except on the two abdominal segments seen from above, which are strongly and closely punctured. In its general facies it is like H. 4-notatus, being wider and less convex than H. unicolor, and the interstice between the inner thoracic stria and the outer margin is wider and the short stria is more in the centre of this interstice.
This is also from vicinity of the Ishikari river."
