FEMALE—Length 8 mm.; length of face about equal to distance between eyes above; eyes very slightly convergent below; hind margin of vertex broadly incurved, lateral ocelli separated from its hind margin by slightly more than their diameter; cheeks somewhat swollen, considerably broader than eyes (ratio of about 3:2); process of labrum broadly rounded, extensive, covering most of surface of labrum; facial foveae narrow, extending from level of antennae to near top of eye; basal segment of flagellum only slightly shorter than segments 2 and 3 combined; surface of head shining, punctures fine but rather distinct, rather close on vertex between eyes and ocelli and on sides of face, but becoming quite sparse on clypeus and supraclypeal area, those on cheeks very fine, evenly distributed and quite sparse above, but becoming very sparse on either side of hypostomal carinae beneath; pubescence of entire head, thorax and legs pale ochraceous, erect but rather thin and short; tegulae yellowish-hyaline; wings faintly yellowish, veins and stigma testaceous; legs entirely dark; spurs pale testaceous, hind tibial scopa of rather elongate, simple, loose hairs; dorsum of thorax shining, scutum doubly punctate, with numerous very fine and somewhat close punctures, with coarser and much more sparse punctures interspersed, those on scutellum rather close and irregular, the metanotum also somewhat shining, with very minute and rather close punctures; pleura less shining, the punctures somewhat coarser but quite shallow and well separated; dorsal area of propodeum quite short, finely subrugose across base, the outer margin becoming smooth, almost shining, lateral and posterior faces quite smooth; basal abdominal tergum smooth and shining, almost polished, with exceedingly minute and obscure, scattered punctures, those on segments 2-4 more distinct but still very fine and quite close, the surface less shining, apical margins of the terga impressed for about one- third the median length, this area slightly yellowish toward rim, nearly impunctate, discal pubescence very short, thin, erect, entirely pale, apical fimbria somewhat yellowish.
MALE—Length 7 mm.; black, clypeus entirely yellow; length of face nearly equal to distance between eyes above; clypeus short and broad, protruding about one-third below suborbital line; hind margin of vertex strongly incurved, lateral ocelli removed from its hind margin by somewhat more than their diameter; cheeks somewhat swollen, considerably broader than eyes; process of labrum large, semicircular, shining, occupying most of upper surface of labrum; facial foveae small but distinct; basal segment of flagellum slightly longer than segment 2; face smooth and shining, punctures shallow, fine and rather obscure, but quite close on vertex between eyes and ocelli, becoming somewhat deeper and more distinct towards sides of face below, rather sparse below antennae and over most of clypeus; punctures of cheeks - fine, close, rather distinct, becoming quite sparse beneath, surface shining; pubescence of entire head, thorax and legs whitish-ochraceous, rather thin and short but erect; tegulae yellowish-hyaline; wings faintly yellowish, veins and stigma more testaceous; legs piceous or blackish basally, front tibiae anteriorly and all tarsi yellowish; spurs yellowish; dorsum of thorax shining beneath loose pubescence, punctures rather shallow and indistinct, variable, rather well separated over most of scutum, but hardly sparse; pleura not so shining, punctures very fine, shallow, rather sparse; dorsal area of propodeum dull but relatively smooth, lateral and posterior faces tessellate, with a few shallow, obscure punctures; abdominal terga somewhat shining, punctures exceedingly minute and obscure, rather close in general, apical margins of plates impressed for about one-third their median length, these areas impunctate, shining, becoming yellowish along rims, discal pubescence very short, thin, obscure, entirely pale; sternum .6 rather abruptly narrowed apically, this margin slightly incurved, densely short setose; apical margin of sternum 7 slightly incurved, with a ventrally directed and somewhat bulbous median projection; apical process of sternum 8 abruptly dilated and flexed ventrally; gonostyli slender, parallel-sided except for the somewhat constricted base, setose toward base, about attaining tips of penis valves, these strongly constricted at base, slightly flexed medially, flattened, tips very slightly bulbous, bearing a rather strong fringe of hairs beneath near center.
DISTRIBUTION—Texas to Mississippi; April.
