100 HYMENOPTERA. 



This species is about the same size as the Ponera contracta of 

 Europe, which it also closely resembles. 



Species of Mexico. 



59. PONERA FERRUGINEA. B.M. 



Female. Length 2J lines. Ferruginous : the head scarcely 

 wider than the thorax ; the mandibles stout and strongly denti- 

 culate on their inner margin ; the head slightly emarginate be- 

 hind. Thorax oblong-ovate, the metathorax obliquely truncated, 

 the truncation smooth and shining. The abdomen elongate- 

 ovate ; the node of the peduncle incrassate, its superior margin 

 rounded, slightly convex in front and concave behind, the con- 

 cavity smooth and shining. 



Hab. Mexico. 



60. PONERA BICOLOR. 



Ponera bicolor, Guer. Icon. Reg. Anim. Ins. iii. 424. 

 Hab. Mexico. 



Genus 4. PARAPONERA. PI. VII. figs. 7, 8, 9. 



Head subquadrate, with the angles rounded, slightly narrowed 

 posteriorly ; the eyes circular and very prominent, situated a little 

 before the middle, at the sides of the head ; the antennae inserted 

 forward on the face in deep cavities close to the base of the cly- 

 peus ; mandibles large, triangular, dentate on their inner edge ; 

 the labial palpi 3-jointed, the maxillary palpi 5-jointed ; the node 

 of the abdomen incrassate ; the abdomen with a deep strangula- 

 tion between the first and second segments. 



This insect, which is now separated from the genus Ponera, 

 will not range in any of the subdivisions here described ; in the 

 prominence of the eyes it agrees with the genus Ectatomma, but 

 the labial and maxillary palpi are composed of a different number 

 of joints.
