THE GROUND BEETLES. 191 



LXXI. BRADYCELLL-S Er. 1882. (G-r., " slow + footed.") 



Small brown or piceous bettles known from allied genera by the 

 mentum bearing a rather large acute tooth. The elytra are 

 obliquely but feebly sinuate at tip and the second striae bears a 

 dorsal puncture behind the middle. Two species have been taken 

 in Indiana, while three others perhaps occur. For literature see 

 above under Agonoderus.

Elongate, subdepressed. Dark reddish-brown to piceous, shining, the 

 margins usually paler; anteun;e reddish-brown, the two basal joints and 

 legs dull yellow. Eyes very small. Thorax much longer than wide, sides 

 curved in front, sinuate behind the middle: base distinctly narrower I ban 

 apex: disk with a deep entire median impressed line, a number of coarse 

 punctures near apex and in the basal impressions ; hind angles rectangular.

 tellar one represented by a large puncture; intervals convex. Length 5 

 5.5 mm. 



Knox County; rare. April 20. In form of body and general 

 appearance it resembles a small Pterostichus. 



B. neglectus Lee., black or piceous with legs and antennae pale, 

 and B. cordicollis Lee., black with legs pale, are both boreal species 

 which may occur in northern Indiana. H. fantillus Uej., black or 

 piceous with pale legs and antenna 1 , may also occur in the State.
