Fountain, Vigo, Crawford and Posey counties; scarce April

 taken from decaying fleshy fungi. Resembles the female of exca-

 reddish-brown. Head with a shallow transverse groove in front of eyes. 

 Thorax two and a half times as wide as long, surface densely and rather

 but distinctly punctulate. Length 4.5-5.5 mm. 



Putnam, Vigo and Posey counties ; scarce. March 4-November 

 7. Occurs especially beneath bark of elm. The oblong form, brassy 

 lustre and larger impressions at base of thorax serve to distinguish 

 this form from all its allies.
