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:
