the face, which is canaliculated; the antennz black, the base 
and apex of the scape sometimes rufo-piceous ; the inner orbits 
of the eyes and the clypeus, which is produced in the centre, in 
front, into a tooth, covered with a dense silvery down; the 
mandibles towards their apex piceous. 
The thorax narrower than the head, somewhat shining; the

former with two central parallel impressions at its base extending 
to the disk; the metathorax consute at its extreme base, smooth
