Each elytron at the extreme base and on the hinder disc with ten, on the anterior disc with nine, rows of large, deeply impressed punctures, the second and fourth interspaces rather strongly and equally costate, the eighth interspace less strongly elevated, the sixth interspace thickened at its apex, the suture also thickened.^[2]
