THE GBOUND BEETLES. 



19] 



LXXI. Bradycellus Er. 1832. (Gr., ' 1 slow + footed. " ) 



Small brown or piceous bottles 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. 



KEY TO INDIANA SPECIES OF BRADYCELLES. 



a. Form very elongate : thorax with a deep marginal line, its basal impres- 

 sions long and deep ; middle tarsi of male with small scales beneath. 



359. LIXEARES. 



aa. Form much less elongate: thoracic margin narrow; basal impressions 

 short, not deep: middle tarsi of male without scales. 

 ~b. Hind angles of thorax broadly rounded, scarcely punctured: length 

 3.2 mm. xeglectes. 

 bl). Hind angles of thorax distinct. 



G. Thorax without punctures near the hind angles: length 5 mm. 



CORDICOLI.IS. 



cc. Thorax distinctly punctured. 



d. Basal impressions broad, shallow, strongly punctured: sides 

 obliquely subsinuate near base; length 4.8 mm.

359 (1154). Bradycelees lixearis Lee. X. Sp. X. Amer. Col.. I. 1863. 16. 



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

 margins usually paler : antennae 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 than 

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

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

 Elytra at base wider than thorax, long and parallel ; stria? deep, the scu- 

 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 PterosticJius. 



B. neglechis Lee. black or piceous with legs and antenna- pale, 

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

 which may occur in northern Indiana. B. tantilhis Dej.. black or 

 piceous with pale legs and antennae may also occur in the State.
