 narrowed in front, so that when the mandibles are closed it appears 

 fairly triangular ; it is somewhat wider than the thorax, coarsely 

 rugose lengthwise, finely and closely punctured between the rugae, 

 the posterior angles bearing a small tooth. The lateral margins of 

 the head, from the posterior end of the scrobes to the posterior 

 angles, are denticulate. Eyes much more convex than in the 9 • 

 The sculpture of the thorax is about the same as that of the head ; 

 the epinotal teeth are smaller than in the 9 . wide at the base, thin 

 near the apex. The mesosternum has a dentiform anterior angle. 

 The petiole is very coarsely and longitudinally striate, and, in addition, 

 very closely and finely punctate ; the 2nd node hardly wider than 

 long. The 1st abdominal segmeut is very finely reticulate and 

 nitidulous, near the base also longitudinally striate.

^ . 3 - 9-4 - 2 mm. The sculpture of the head is more or less 

 reticulate and composed mainly of longitudinal strands with short 

 transverse bars. The sculpture is stronger than in Baumi var. batonga. 

 The denticulations round the margins of the head are fairly prominent, 

 and the 2 teeth near the posterior angles are proportionately much 

 larger than in batonga. The spaces between the reticulations on the 

 head and thorax are feebly shining and microscopically rugulose. 

 The thorax is longitudinally rugulose, more transversely reticulate- 

 rugose on the anterior half of the pronotum. The fundamental 

 sculpture of the abdomen is densely and finely reticulate-punctate ; 

 the coarser sculpture is longitudinally rugose, the rugae wide, ex- 

 tending from base to apex, deeply siucate between the rugae. The 

 sulcate abdomen distinguishes this from our other two small species, 

 brevisetosus and Marleyi. The mesosternal teeth are much larger, 

 longer, and more acute than in either of those two species or Baumi
