£ . 3-3 - 5 mm. Head, thorax, and nodes castaneous brown, the 

 head, especially the anterior half, lighter; nodes darker. Abdomen 

 piceous. Legs, antennae, and mandibles dark yellowish -red, the 

 femora somewhat brownish-red. Pilosity and pubescence almost

 legs and antennae. Very shining, sides of epinotum slightly dull. 

 Head, dorsum of thorax, and the nodes sparsely, irregularly, but 

 deeply punctured ; the sides and front of the head, excepting the 

 clypeus and the sides of the mesothorax, longitudinally rugose. 

 Sides of epinotum closely reticulate-punctate, the declivity transversely 

 striate. The sides of the prothorax and the mesosterna smooth and 

 shining. The apical half of the dorsum of the epinotum rugulose

Head rectangular, parallel-sided, excluding the mandibles almost 

 one-third longer than wide, the posterior margin slightly concave in 

 the middle. Eyes large, placed in the middle of the sides. Frontal 

 carinae wide apart in front, moderately divergent for a short distance 

 behind the clypeus, thence parallel and prolonged back to the posterior 

 seventh of the head, forming the upper boundary of a deep and smooth 

 scrobe. Scapes curved near the base, broad, flattened, not reaching
