eyes as are the eyes, temples strongly convex, occiput rather shal- 

 lowly concave, cephalo-caudad length of temple subequal with that 

 of the eye ; head from in front nearly round, the cheeks strongly con- 

 vex, face slightly narrower than frons, malar space slightly shorter 

 than basal width of mandible; sternauli rather strong; antennae 

 slender, first joint of flagellum slightly longer than second; propo- 

 deum with apical carina obsolete medially, basal areas punctate, 

 others irregularly rugidose, basal carina strongly curved but not sub- 

 angulate medially; propodeal spiracles rather long oval; nervellus 

 broken only slightly below middle ; abdomen opaquely granulate, the 

 middle tergites weakly, rather densely, punctate; first tergite with 

 strong dorsal carinae becoming, obsolete beyond the spiracles, sub- 

 polished medially, densely punctate laterally, nearly twice as wide at 

 apex as at base, weakly elevated in the middle; ovipositor three- 

 fourths as long as abdomen. 



Black, with posterior orbits brownish; antennae white annulate; 

 clypeus and mandibles piceous; all coxae black, legs otherwise pice- 

 ous except that the hind femur is bright testaceous and the hind tibia 

 only slightly darkened; tegulae piceous; wings slightly brownish 

 the bands somewhat darker brown; abdomen rufous with the apical 

 segments black ; sheath black, reddish at extreme apex.

 Head behind eyes as broad as eyes; face slightly narrower than 

 frons ; cephalo-caudad length of lower temples distinctly shorter than 

 greatest width of eye ; malar space about two-thirds as long as basal 

 width of mandible; clypeus broadly truncate, with a median tooth 

 flanked on either side by a transverse impression; face and frons 

 densely punctate, vertex and temples less strongly so; first flagellar 

 joint distinctly longer than second ; thorax densely punctate, striately 

 so laterally; notauli distinct, transversely striate, extending well on 

 to disk of meoscutum ; sternauli distinct for about three-fifths their 

 length ; propodeum with two complete carinae, the posterior elevated 

 laterally, basal median area weakly defined, basal areas rather 

 sparsely punctate; other areas rugoso-punctate, spiracle round; ner- 

 vellus broken distinctly below middle, discocubitus angulate with a 

 stump at its middle ; first tergite at apex narrower than distance from 

 spiracles to apex, dorsal carinae broadening into ridges be3^ond 

 spiracle, the space between impressed, the segment finely cariaceous 

 medially, punctate laterally; middle tergites densely, finely punc-
