medially; notauli punctate or foveolate; lateral lobes of mesoscutum with only 
a few scattered hairs along inner and anterior margins; propodeum rugose reticu- 
late, sometimes with a suggestion of areolation; radial cell distinctly more than 
half as long as stigma; first abscissa of radius very short, somewhat oblique; 
second abscissa of radius not strongly curved; lower abscissa of basella subequal 
to upper abscissa and to nervellus; nervellus slightly inclivous; abdomen in 
widest part as wide as thorax; first tergite a little more than twice as long as 
broad at apex, closely aciculate from base to apex; suture between second and 
third tergites distinctly indicated; ovipositor sheaths as long as posterior femur. 
Head brownish yellow, sometimes mostly piceous above and behind; antennae 
dark brown, scape and pedicel paler; thorax black or piceous; abdomen varying

Length 3 to 4mm. Face weakly indefinitely sculptured; malar space about

strongly convex in male and about as broad as eyes, only slightly convex and 
narrower than eyes in female; antennae longer than body, with 28 to 34 segments 
in female and 35 to 40 in male; notauli foveolate; mesoscutum with a rugulose 
area on posterior middle; lobes smooth, hairy; propodeum coarsely rugose, 
exareolate, strongly declivous behind, the posterior face longer than the dorsal 
face and conspicuously excavated down the middle; side of pronotum mostly 
rugulose; stigma large; radial cell nearly as long as stigma; lower abscissa of 
basella not longer than upper abscissa; abdomen narrower than thorax; first 
abdominal tergite more than three times as long as broad at apex, fully as long 
as posterior femur, longitudinally aciculate, smooth at base; ovipositor sheaths 
longer than first tergite. 
Female entirely yellow, with antennae brown, paler toward base, and pro- 
podeum occasionally somewhat brownish; male with dorsum of thorax more or 
less piceous or brownish; wings hyaline; subdiscoideus pigmented to wing margin;
