Worker major. Length 5-5.6 mm. 



Head large, regularly oblong, 1^ times a^ long as broad, equally flattened 

 above and below, obliquely truncated in the clypeal region, with the cheeks 

 swollen and rounded and their borders projecting anteriorly around the in- 

 sertions of the mandibles as curved plates ; the region in front of the eyes and 

 near the frontal carinae distinctly impressed on each side ; the eyes rather small 

 and flat, their anterior orbits just in front of the posterior third of the head. 

 Mandibles very stout and convex, with five obtuse teeth. Palpi very short. 

 Clypeus with distinct median and lateral portions, the former ecarinate, con- 

 sisting of two planes, a posterior continuing the dorsal surface of the head, 

 rectangular and nearly twice as broad as long, and an anterior, obliquely 

 sloping and semicircular, its median curved edge forming the anterior border 

 of the clypeus. The triangular, scale-like lateral portions of the clypeus are 

 marked off by grooves that terminate behind in the small but distinct cljrpeal 

 foveae. Frontal area indistinct; frontal groove delicate; frontal carinae long, 

 lyriform, continued nearly as far back as the posterior orbits, diverging behind
