their length (front to back) nearly as great as that of eye; diameter 

 of lateral ocellus nearly as long as postocellar line but only a little 

 more than half as long as ocellocular line ; malar space about half as 

 long as basal width of mandible; cheeks in front view straight and 

 long; clypeus medially swollen, apicall}^ broadly emarginate; man- 

 dibles broad, upper tooth larger but not longer than lower tooth; 

 antennae nearly as long as body, 30-jointed, slender, first joint of 

 flagellum fully four times as long as thick at apex. Thorax rather 

 slender, hardly two-thirds as deep as long, polished, minutely 

 sparsely punctate on mesoscutum and lower mesopleurum, meso- 

 sternum more distinctly and more densely so ; epomia apparently en- 

 tirely absent; notauli very weakly indicated anteriorly; scutellum 

 very strongly convex, not at all margined laterally; propodeum 

 weakly roughened, subopaque, areola flattened but only weakly out- 

 lined, apical carina distinct laterally but obsolete medially ; legs slen- 

 der, hind tibia and tarsus of equal length, inner calcarium half as 

 long as basitarsus; radial cell barely as long on metatarsus as 

 stigma ; areolet incomplete ; nervulus postf ureal ; postnervulus broken 

 in middle ; nervellus broken at lower third, inclivous. Abdomen about 

 a third longer than head and thorax, nearly parallel-sided for most 

 of its length; first segment distinctly longer than broad at apex, 

 its sides diverging very gradually, medially impressed, the impres- 

 sion flanked by weak carinae; tergites 2 and 3 each about as long 

 as broad at their junction, tergite 4 distinctly shorter; tergites 1 

 and 2 and base of 3 weakly alutaceous, abdomen otherwise polished; 

 sheath short and nearly oval.

 ginous, mandibles and tegulae whitish; wings hyaline, venation 

 brown, stigma paler; legs ferruginous, trochanters, tarsi, and hind 

 tibia whitish, apical joints of all tarsi, apices of all joints of hind 

 tarsus, and apex of hind tibia blackish. 



Male. — Essentially like female but malar space shorter, medial 

 swelling and apical angles of clypeus less prominent, abdomen a little 

 shorter, face and clypeus white, front coxae whitish, hind tibia with 

 an obscure subbasal dark annulus.

In Schmiedeknecht's key to European species, this species runs 

 to dorsalis (Gravenhorst), with which it is obviously closely related.
