Head about one-fourth longer than broad, posterior border con- 

 yexly excised, occipital corners evenly rounded: sides ])Osterior of 

 eyes nearly straight, in front of eyes feebly convex. Mandibles 

 straight, rather thick, more than half as long as head, with two long 

 terminal spines which have a shorter spine between them and one 

 subapical spine, situated near the basal apical and about one-third 

 its length. Clypeus nearly as long as broad, narrowed behind, trun- 

 cate at anterior border. Frontal carinae straight, divergent, bor- 

 dering scrobes, three-fourths as long as the head and containing the 

 entire antennal scapes. Antennal scapes extending about three- 

 fourths the distance to occipital corners ; funiculus not very slender, 

 first joint longer than the second and third together, second and third 

 joints about as broad as long. Eye slightly convex. Pronotum 

 nearly fiat, humeri obtusely angulate. Mesoepinotal suture rather 

 strongly impressed. Epinotal base fiat, longer than the declivity, 

 spines shorter than their distance apart at base, 

 acute at tips, lamellate beneath, the lamellae con- 

 tinuing as margins to the declivity. Petiolar 

 peduncle slender, as long as the subglobose node 

 which rises abruptly from it. Postpetiole oval, 

 transverse, one-half broader than the petiole. 

 Legs slender. 



Gaster and dorsum of postpetiole strongly shin- 

 ing and smooth except for short costae at base of fig. is. — strumi-

Ocelli small. Mandibles shorter than in worker. Epinotal spines
