This genus differs from the preceding by having the antennas 

 very hairy; front tibia 1 suddenly thickened at apex; thorax cylin- 

 drical and unarmed ; pubescence of elytra more dense and close with 

 a few erect short hairs proceeding from rows of granules. Three 

 species are known, two of which may occur in Indiana, though but 

 one has as yet been taken.
