Though allied to O. luteipennis, this insect is readily distinguished by the polished 
surface, with greatly diminished sculpture, and the obsolete thoracic grooves. The 
head is sparingly punctate, the front of the clypeus is rather depressed, and forms a 
minute projection in the middle. There is a fine obsolete groove along the middle of 
the thorax, and the lateral grooves can usually be detected, but they are abbreviated and 
very obsolete. The elytra are longer than the thorax, their sculpture much effaced, 
polished. The male has a larger head than the female, and the hind margin of the 
last ventral plate is prolonged in the middle to form a short, broad lobe. The species 
varies in colour from a piceous to a flavescent tint, and the sculpture is in some examples 
considerably less effaced than it is in others.
