the hinder margin slightly concave ; mandibles narrow, obscurely 

 longitudinally striate, when closed partially concealed under the 

 projecting margin of the clypeus, the latter obtusely bicarinate : 

 antenna? moderately long, the scape not quite attaining the poste- 

 rior margin of the head ; eyes comparatively large and flat, placed 

 about the middle of the side of the head. Thorax anteriorly 

 rounded, moderately broad, the meso- and metanotum narrow and 

 strongly compressed, the meso-metanotal suture distinct; the 

 thorax in profile emarginate at the suture, the basal portion of 

 the metanotum broadening posteriorly. Pedicel : the nodes, seen 

 from above, nearly equal, the rounded 1st node higher than the 

 2nd and petiolate anteriorly ; abdomen oval. 



5 . Closely resembles the $ , but larger. Head a little broader 

 than long, plainly longitudinally striate. Thorax obscurely trans- 

 versely striate, the mesonotum narrow, very gibbous anteriorly ; 

 metanotum broadening posteriorly, concave apically from side to 

 side, the concavity more coarsely transversely striate. Pedicel : 

 the 1st node anteriorly petiolate, cuneiform, higher, somewhat 

 sharper above than the 2nd node, which is transverse, rounded 

 above ; abdomen long and massive, the posterior margins of the 

 segments bright yellow. Colour entirely as in the ; pilosity 

 short and somewhat abundant. Wings hyaline, nervures pale 

 yellow.

$ . Dull sordid brownish yellow, the apical two-thirds of the

 very sparse, reduced to a long soft hair here and there. Head 

 subrectangular with the angles rounded, the sides of the head 

 slightly convex, posteriorly broad, as broad as in front ; mandibles 

 smooth and shining, with a few punctures and obscure striae; 

 clypeus very convex in the middle, the medial posteriorly con- 

 vergent carinse not very distinct ; antennae 12-jointed, the scape 

 not quite reaching the top of the head ; eyes of moderate 

 si/.e, lateral, placed very little below the middle of the head. 

 Thorax : the pro-mesouotum very convex, rounded anteriorly and 

 at the sides ; meso-metanotal suture deeply impressed, the thorax 

 distinctly emarginate at the suture ; basal portion of metanotum 

 rouuded, convex at the sides, a little flat above, and passing by a
