Mandibles narrow, with two or three teeth. Clypeus convex, 

 with rounded entire anterior border. Antennal scapes slender, 

 somewhat shorter than the head ; funiculi with joints gradu- 

 ally increasing in length distally, but without distinct club ; 

 first joint slightly swollen. Thorax large; mesonotum, seen 

 from above, as long as broad, very convex, especially in front, 

 where it strongly overarches the very small pronotum. Meso- 

 sterna and mesopleurae large and very convex. Epinotum 

 narrow, prolonged backward, its base rapidly sloping and 

 more concave anteriorly, its posterior portion somewhat 

 higher, subnodiform, and with very short declivity. Petiolar 

 and postpetiolar nodes low and rounded, the latter longer 

 than broad and somewhat broader than the former. Legs 

 long and very slender. Venation of wings as in the female. 



Pilosity and sculpture much as in the worker, but the 

 hairs somewhat finer and the head much less rugose in front, 

 the mesopleurae and upper-surface of the epinotum smooth 

 and shining and the mandibles shining and sparsely punctate. 



Colour as in the female, but the head darker, the 

 mandibles yellow, and the wings and apterostigma somewhat 

 paler.

Although series of specimens from different localities vary 

 more or less in average size, in colour, sculpture, and the 

 length and shape of the epinotal spines, it seems inadvisable 

 on the basis of the material examined to confer names on the 

 varieties of this species.
