 cimen.

 and feet rufous. 



Inhabits New Hampshire and Pennsylvania. 



Body blackish, with pale hairs and minute punctures : clypeus 

 with larger punctures than the thorax j two obsoletcly impressed 

 diverging lines ; anterior edge subangulated, and the angles so 

 depressed as to appear confluent with the anterior part of the 

 head : antenna3 rufous, a little hairy j second joint two-thirds the 

 length of the third ; last joint longer than the first, not abruptly 

 contracted towards the tip : thorax convex blackish ; base with 

 a fissure each side ; posterior angles pointing backward, rather 

 obtuse and somewhat broad, with the carinated line rather short,

 punctured striae, more deeply indented at base, and the third and
