 frons evenly convex, scrobes weakly mipressed; eyes shorter than 

 width of face, parallel within ; face medially elevated and more sliin- 

 ing; clypeus as long as face, shining, with a fringe of setae, each seta 

 set in a deep puncture; malar space as long as basal width of 

 mandible; antenna filiform, all flagellar joints longer than thick. 



Thorax shagreened; pronotum in scrobe and mesopleuron above 

 middle polished, the latter with a longitudinal elevation at about the 

 middle; propodeum with median and lateral carinae strong, but api- 

 cal carina weak.

 entire fifth tergite polished : first tergite more strongly striate, trans- 

 verse grooA-e obsolete medially ; tergite 4 with a shallow but distinct 

 transverse groove, and tergite 5 with a faint trace of a groove; ovi-
