the eyes than long; antenniferous tubercles usually small, 

 widely separated, in our species usually armed above on outer

 between the antennal bases ; beak reaching middle coxae ; an- 

 tennae half the length of body, first joint moderately stout, 

 feebly curved, one-half or more the length of head, 2 and 3 

 more slender, the second longest, fourth a little thicker, fusi-
