Soldier: Length, 3 mm. Head about twice as long as 

 broad, the sides parallel, faintly narrower posteriorly and 

 with the angles rounded, the occiput deeply emarginate 

 and with a deep median channel extending nearly to the 

 clypeus. Frontal area minute, oval, deeply impressed. 

 Clypeus very short, transverse, sinuate in front and be- 

 hind; the anterior margin deeply emarginate at the mid- 

 dle. Antennge short, the scape about one-half the length 

 of the head. Mandibles robust, the cutting edge with 

 two or three teeth at the apex. 



A deep constriction between the meso- and metanotum. 

 Lateral angles of the pronotum obtusely rounded; meta- 

 notum with two short, erect, stout spines. Nodes as in 

 the worker. 



Vertex finely and transversely striated and more or less 

 strongly rugose at the posterior angles, the stride inter- 

 spersed with coarse punctures; face and clypeus longitu- 

 dinally striated, the strias becoming more rugulose between 

 the eyes and frontal carince. Mandibles polished, sparsely 

 punctured and with a row of coarser, elongated punctures 

 near the cutting edge.
