 closely punctate, the tips subemarginate. Length 4-7 mm. 



Lake, Porter and Kosciusko counties : frequent beneath the bark 

 and on the dead limbs of pine. June 15-JuIy 23. Said to occur

LXV. Ecyrus LeConte. 1852. 



This genus differs from the preceding by having the antennae 

 very hairy ; front tibia? 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.
