toward their tips. All the funicular joints except the first sub- 
equal, first joint almost equal to the next two in length. Thorax 
robust, pronotum about as broad as long, convex. Meso-epinotal 
constriction distinct but not deep. Epinotal base and declivity 
meeting in such a way as to form a decided angle. Petiole low, 
convex and rounded in front and above, flattened behind, the 
posterior dorsal edge of the node faintly impressed in the middle 
but not excised or emarginate. Gaster oblong. Legs short, 
femora compressed, anterior pair distinctly dilated. 
Mandibles and anterior two thirds of head subopaque, the 
former obscurely longitudinally rugose, the latter coarsely and 
irregularly reticulate — rugose, with punctate interrugal spaces. 
On the cheeks and front the sculpture gradually passes over 
into umbilicately punctate, shallow and scattered foveolse.
