Described from specimens taken from a small colony beneath a stone 

 and from several isolated workers.

 petiolar node is not broader than long and the color is lighter.

 occipital corners; funiculus stout, joints two to eight strongly transverse, 

 terminal joint longer than the two preceding joints taken together. Ej'^es 

 large and convex, located at sides of head at a distance equal to their longi- 

 tudinal diameter from anterior corners. Thorax robust, evenly convex above. 

 Epinotal spines triangular, rather stout, about as long as broad at base: epi-
