sides and are large and flat; occipital border widely and 
feebly concave. 
Mandibles long, with seven large teeth, followed by a few 
minute ones along the first half of terminal border. Ante-

first joint of scape slightly longer than the following one, the 
remaining joints gradually diminishing to the apex. Scapes 
pass the occiput by a little more than their width. 
Promesonotum in profile evenly arched, with hardly any 
break between the two segments. Mesoepinotal incision 
deep, the epinotum evenly rounded, the declivity longer than 
the base (v. fig. 1). Node squamiform. 
Mandibles shining and closely punctured. Whole body 
covered with a fine reticulation, hidden under the pubescence 
except under a high power.
