thirds total width ; eyes very weakly emarginate, distinctly converg- 

 ent below; face distinctly broader than long, sparsely and finely 

 punctate, in profile strongly convex; clypeus twice as broad as long, 

 truncate at apex ; malar space about half as long as basal width of 

 mandible; occipital carina extending straight to base of mandible; 

 antennae 33-jointed, basal joint of flagellum about five times as long 

 as thick and nearly twice as long as second, subapical joints much less 

 than twice as thick as first. 



Thorax slightly deeper than long, polished, mesoscutum and scu- 

 tellum very sparsely and finely punctate, propodeum very uniformly 

 and finely shagreened and subopaque; epomia entirely absent; pre- 

 pectal carina ascending about halfway up anterior margin of meso- 

 pleurum and ventrally approaching very closely the posterior carina 

 of the sternum; mesopleural scrobe very strongly oblique; notauli 

 represented anteriorly by small shallow pits; scutellum as broad as 

 long, moderately convex, margined to apex, its fovea shallow,

smooth, not limited anteriorly by a carina ; propodeum incompletely 

 areolated, the lateral carinae lacking except at apex and the areola 

 and petiolar area confluent, parallel-sided posteriorly, acutely 

 pointed basally, all five apical areas defined. Intercubitus more than 

 half as long as space between it and recurrent ; nervulus postfurcal 

 by much more than its length ; abscissula nearly half as long as in- 

 tercubitella. 



Abdomen polished, with sparse minute punctation and pubescence, 

 first tergite virtually impunctate and glabrous; postpetiole much 

 broader than petiole ; second tergite distinctly shorter than first and 

 little more than twice as long as broad at base, without trace of 

 gastrocoeli, spiracles distinctly behind middle; tergites 2-6 with 

 broad, transparent epipleura; ovipositor sheath as long as first 

 segment. 



Head and thorax yellow with black markings as follows : Occiput 

 and posterior margin of vertex and temples, narrowly joined to a 

 triangular spot enclosing the ocelli; a medium stripe in anterior 

 two-tliirds of mesoscutum and a U-shaped mark with its base in
