the posterior lateral lobes coarsely reticulate, the broad longi- 

 tudinally impressed medial Hue finely transversely striate ; man- 

 dibles smooth, polished, shining, delicately punctured; clypeus 

 with its anterior margin medially bi-angular, above which is a V- 

 shaped depression ; antennal carinae short, divergent ; antennal 

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

 for little more than half the distance between its insertion and 

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

 transverse mesonotal groove and ridge and transverse emargination 

 at the meso-metanotal suture distinct ; basal face of the metanotum 

 flat, square, submargined laterally ; rnetanotal 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, finely and closely longi- 

 tudinally striate at base. 



. Pale brownish yellow, the head and abdomen darker than 

 the thorax, the whole insect shining but covered somewhat densely 

 with pale yellow erect hairs; head oval, eyes comparatively large; 

 thorax elongate, the pro-meso- and meso-metanotal sutures 

 distinct, the transverse mesonotal groove slight, the basal portion 

 of the metanotum longer than broad, flat, the metanotal spines 

 stout. Pedicel elongate, the 1st node with an indistinct appendix 

 beneath, the 2nd node from above circular, convex; abdomen.

11 . Head, thorax and 1st node of the pedicel dark castaneous 

 browu, flagellum of the antenna? and legs light brownish red, 2nd 

 node of the pedicel and the abdomen black. Head, thorax and 

 abdomen covered with long erect red hairs ; head broader poste- 

 riorly than in front, with an indistinct or no transverse impression 

 on the vertex, closely longitudinally striate ; mandibles shining, 

 sparsely punctured ; clypeus medially shortly carinate, anteriorly 

 emarginate in the middle; antennal carinae short, posteriorly 

 divergent, antennal groove distinct, finely sculptured within'; 

 scape of the antennae extending about two-thirds of the distance 

 between its insertion and the top ot the head. Thorax anteriorly 

 convex and transversely striate, the transverse mesonotal groove 

 shallow, the thorax deeply emarginate at the meso-metanotal 

 suture : the basal portion* of the metanotum flat, longer than 

 broad ; metanotal spines stout, erect and acute. Pedicel : the 1st 

 node cuneiform, the upper margin transverse, slightly emarginate, 

 a rounded laterally compressed appendix beneath ; 2nd node not
