front not much narrower than the head, the thoracic constriction at 

 the meso-epinotal suture feeble, the suture shallow. Dorsum of 

 epinotum three-fifths as long as the pro-mesonotum, twice as long as 

 the declivity, the latter sub-vertical. The epinotum is barely excavated 

 above. Peduncle of the 1st joint of the petiole shorter than the node 

 the latter is cuneiform, higher than the 2nd node, and measured along 

 its base, longer than wide. Second node slightly narrowed behind, a 

 little wider than the 1st. This species greatly resembles albopilosum, 

 var. tholes, but may be distinguished from it by the thinner 1st node 

 and the shorter peduncle.

 and flatter below, the 1st node thicker. The epinotum is also less 

 arched, and lies lower.

 Thorax closely and finely reticulate. Abdomen very sparsely pilose. 

 Head, excluding the mandibles, one-sixth longer than wide, the sides
