 tudinally impressed medial line finely transversely striate ; man- 

 dibles sinooth, polished, shining, delicately punctured; clypeus 

 with its anterior margin medially bi-angular, abo\e which is a V- 

 shaped depression ; antennal carinte short, dixei'gent ; anteiinal 

 groove shallow, as long as the scape ; this latter short, extending 

 for little more than bait' the distance between its insertion and 

 the top of the head. Tliorax transversely striate anteriorly, the 

 transverse mesonotal groove and ridge and transverse emargination 

 at the meso-metanotal suture distinct; basal face of th(> metanotiim 

 tlat, square, subniargined laterally ; metauotal spines erect and 

 stout. Anterior node of the pedicel smooth and shining, with a 

 transverse margin above, beneath with a laterally compressed 

 rounded appendix ; posterior node twice as broad as long, rounded 

 above ; abdomen broadly oval, shining, linely and closely longi- 

 tudinally striate at base.
