strongly marginate, the margination running around the posterior 

 corners and along the ventral surface on each side about § the length 

 of the head. Eyes and ocelli absent. Mandibles small, abruptly 

 flexed at their bases, with deflected blades, the apical margins very 

 indistinctly denticulate. Clypeus very short. Frontal carinse closely 

 approximated, in front surrounding the antennal insertions, behind 

 fused and truncated in a depression which unites the antennal fovese. 

 Carinae of cheeks sharp, abruptly and angularly turned inward behind 

 towards the antennal fovete. Antennae robust; scapes about half 

 as long as the head, thickened apically ; first funicular joint as long as 

 broad; joints 2-9 broader than long, apical joint enlarged, glandiform, 

 as long as the four preceding joints together. Thorax about 2^ times

as long as broad, its dorsal surface flattened, with a very feeble trans- 

 verse depression marking the obsolete mesoepinotal suture; epinotum 

 abruptly truncated behind, distinctly concave in profile; pronotum 

 marginate in front; epinotal declivity sharply marginate on the sides 

 and above, on each side abo^^e very feebly subdentate. Mesopleurse 

 rather concave. Petiole from above rectangular, distinctly longer 

 than broad, scarcely broader behind than in front, narrower than the 

 epinotum, with straight, silbparallel sides, rather rounded, convex 

 dorsal surface and a sharp, angular tooth, directed forward and down- 

 ward on its anteroventral surface. Postpetiole broader than the 

 petiole, as long as broad and distinctly broader behind than in front, 

 with straight sides and anterior border, its ventral portion in front
