PONERA, Lat. 

 The males and females armed with a sting ; pedicle of the abdomen 

 formed of a single scale or knot ; antennae of the individuals men- 

 tioned, thickest towards the end ; mandibles triangular, and the head

 mandibles are long, narrow, parallel, and terminated by three teeth. 

 All the species are foreign to Europe *.
