434 FAMILY XL STAPHYLIXID-i:. 



sifted from a patch of withered fungus. Very probably occurs in 

 southern Indiana. 



GROUP C. (PYCNOKUS.) 



Body rather thick and convex ; legs stout, the front tarsi dilated ; 

 front angles of thorax obliterated. One of the three species as- 

 cribed to the group has been taken in the State.

179. 



Elongate, convex. Black, feebly shining, thinly clothed with very fine 

 gray pubescence; antennae and tarsi dark reddish-brown; legs and abdo- 

 men pic-eons. Head longer than wide, truncate at base, very minutely and 

 sparsely punctate above, more distinctly beneath. Antenna? reaching base 

 of thorax, the outer joints scarcely thicker. Thorax elongate-oval, one- 

 third longer than wide, sides feebly curved, converging from middle to 

 base and apex; disk, as well as that of elytra, finely and sparsely punc- 

 tate. Elytra as long and scarcely wider than thorax. Abdomen as wide 

 as elytra, minutely and densely punctate. Length 3-3.2 mm. 



Kosciusko County; rare. June 24. Sifted from sphagnum 

 moss at edge of tamarack marsh. The males have the femora 

 thicker, the hind ones bent, concave beneath, the curved edge finely 

 serrate and with a tooth near trochauter. 



LIU. STILJCUS Latr. 1S29. (Gr.. "a style.") 



Small slender species having the labrum broadly rounded or 

 subtruncate at apex; second joint of maxillary palpi much shorter 

 than third; head rounded or subtruncate at base; surface usually 

 coarsely punctured. The head is narrowed behind and the thorax 

 in front, the two parts being united by a mere point, giving to them 

 the aspect of small ants. The following species have been taken or 

 probably occur in the State:
