FEMALE Length 8-9 mm.; length of face slightly greater than greatest distance between eyes, these strongly convergent below; malar space linear, almost obliterated; facial foveae also very poorly developed, hardly visible beneath pubescence; mid antennal segments about as broad as long, apical ones somewhat longer; clypeus densely and finely punctate, thinly pubescent; pubescence entirely yellow, prothoracic spines inevident; metapleural protuberance small, inconspicuously carinate, the margin not ferruginous; tegulae pale ferruginous; wings hyaline, somewhat violaceous, veins and stigma brownish to testaceous; punctures of scutum close and deep, obscured by the dense pubescence; anterior half of scutellum smooth, relatively bare, posterior half closely and coarsely punctate and densely pubescent; punctures of pleura close, deep and rather coarse, with copious but not quite so dense pubescence; dorsal area of propodeum shining between the sparse striae; coxal spines well developed; tarsi dark, hind basitarsi slender and elongate, spurs yellowish; punctures of abdominal terga exceedingly minute and obscure, fascine broad, dense and entice, and median segments entirely covered by the dense, appressed, yellow tomentum, apical margins of terga beneath fascine ferruginous-hyaline; pubescence ochraceous throughout.
MALE—Length 7 mm.; length of face slightly greater than greatest distance between eyes; eyes strongly convergent below; length of malar space about one-third its width; width of mid antennal segments two-thirds the length; clypeus very finely and closely punctate beneath the long dense pubescence; pubescence entirely yellow on head and thorax above, more whitish below; prothoracic spines inevident; metapleural protuberance small, inconspicuously carinate, the margin not ferruginous tegulae pale yellow; wings hyaline, somewhat violaceous, vents and stigma brownish to testaceous; scutum finely and rather closely punctate anteriorly, punctures becoming very sparse in center of disc posteriorly, pubescence quite long and dense, but not obscuring the surface; posterior half of scutellum rugoso-punctate, anterior portion smooth; pleura shining, finely and rather sparsely punctate, becoming finely rugose above; dorsal area of propodeum rather closely striate; tarsi testaceous, basitarsi slender and elongate, spurs pale yellow; abdominal terga very minutely and obscurely punctate, basal tergum smooth and shining beneath the long, thin pubescence; abdominal famine dense, entire, whitish and rather broad on segments 1-5, discs appearing dark from the thin covering of fine short hairs, but pubescence entirely pale to tip; apical margins of abdominal terga yellowish-hyaline beneath fasciae.
DISTRIBUTION—Georgia and North Carolina, north to Minnesota, Illinois, Michigan and Massachusetts; July to September.
