piceons, thinly covered with very short pale hairs. Head 

 broader than the thorax, emarginate behind. Eyes large, 

 ovate, prominent, and sitnated anteriorly on the sides of the 

 head. Mandibles stout, triangular, strongly dentated within, 

 and punctured on their upper surface. Scape of the antennae 

 strongly curved, as long as the head. Flagellum clavate, 

 with the last joint the longest. Thorax rounded anteriorly, 

 with a very deep strangulation between the meso- and meta- 

 thorax. Scale of the peduncle large, ovate, and pointed 

 above. Abdomen elongated, so as to be nearly cylindrical 

 as in Ponera. 



I found this insect on the ground, but know nothing of its 

 habits.
