31. PoNERA PtJMILA, N. S.

 small, advanced ; jaws triangular, strongly toothed ; antennae thick- 

 ened ; thorax smooth ; abdominal pedicle long, square ; abdomen

I found this Ant in Malabar where it is rare. 



Foremicites. 



We now come to the last family containing those Ants that have 

 no sting, and the abdominal pedicle of one knot only. It comprises 

 two Genera Polyergus and Formica, but I do not think we possess 

 any species of the former genus. 



Gen. Formica. 



This genus comprises two distinct forms, the one with spines on 

 the thorax, the other unarmed, which certainly ought to form two 

 genera, inasmuch as this distinction is made to separate Att| from 

 Ocodoma. 



1st, without spines on the thorax. 



32. Formica Compressa, Farr. ? 



Syn. F. Indefessa, Sykes.

 eyes medial, of moderate size ; jaws triangular, toothed ; antennae 

 long ; thorax widened anteriorly ; abdominal pedicles somewhat 

 diamond shaped above, much raised and thin as seen laterally ; legs 

 rufous, the rest of the body black.
