 the 3d and -ith sternites have more or less distinct tubercles.

$ Black; anterior knees and tibiae in front and spot on tegulae yel- 

 low, flagellum light brown beneath, tarsi a little brownish, wings hyaline, 

 the nervures brown. 



Head a little longer than broad, the eyes converging below ; clypeus, 

 lower portion of supraclypeal space and sides of face longitudinally 

 lineolate with very shallow rather coarse punctures separated by less 

 than their diameter, those on the sdies of the face coarser and more 

 distinct ; genae longitudinally lineolate with 4 series of large shallow 

 umbilicate punctures, front much more strongly punctate, the punctures 

 seriate along the orbits, interstices tessellate ; vertex unevently punctate 

 the punctures along the occiput confluent ; sulcate longitudinal carina of 

 he middle of supraclypeal area not strong but approaching the anterior 

 ocellus, supraorbital fovea reaching the level of the summit of teh eye. 



Collar with the anterior margin acutely carinate, a median hair patch 

 on its surface, anterior angles acutely subdentate, the surface uneven very 

 minutely tessellate but impunctate mesonotum with strong deeply im 

 pressed coarse punctures confluent anteriorly, from the anterior third 

 posteriorly, the punctures discrete, separated by their own diameter or 

 more interstices strongly tessellate, scutelum similar, metanotum contrast- 

 ing, the punctures coarser and closer, the tessellation of the interstices 

 stronger ; mesopleura similar to the mesonotum. Basal and basolateral 

 areas of propodeum discrete, separated from the posterior face by a 

 strong carina. Basal area with some reticulate pits anteriorly limited 

 by an irregular carina, the resf and the basolateral areas coarsely irreg- 

 ularly reticulate, the surface tessellate, shining. Sides of propodeum 

 opaquely tessellate, finely, stronglj^ and closely punctate, separated from 

 the basolateral and posterior areas by carinae, the posterior face rather 

 coarsely reticulate, the furrow rather narrow and definitely marked. 



Tergites transversely lineolate tessellate, the first microscopically 

 sparsely shallowly punctate, appearing impunctate with a hand lens.
