FEMALE — Length 8 mm.; bluish-green; face considerably longer than distance between eyes above; eyes slightly convergent below; lateral ocelli subequally distant from margin of vertex and each other, slightly more removed from eye; clypeus broadly convex, considerably produced apically, median area of margin nearly straight; median length of labrum considerably less than basal width; mandibles obscurely 4-dentate, as shown (fig. 32); cheeks somewhat broader than eyes; wings subhyaline, very lightly clouded apically, recurrent veins reaching 2nd submarginal cell subequally distant from base and apex; tarsal segments simple and unmodified; mid and hind spurs piceous; pubescence entirely pale, yellowish-white above, becoming more whitish below, and scopa entirely white; discal pubescence of abdominal terga very short and inconspicuous, forming rather loose and indefinite, apical fasciae at sides of 2 and 3 and across entire width of 4 and 5, 6 rather densely covered with subappressed, pale tomentum; punctures deep and distinct, rather fine and close in general, quite uniform over most of head, somewhat more distinctly separated in center of scutum posteriorly, and scutellum with a narrow, impunctate, median line, punctures on each side deep, distinct and quite close; pleura rather dull, punctures rather shallow but closely crowded, becoming slightly separated just beneath tegulae; lateral faces of propodeum somewhat shining, but very finely roughened, posterior face dull, with shallow, indefinite, obscure but rather close punctures, dorsal area rather velvety, but becoming rather broadly and finely striate along upper margin; punctures of abdominal terga deep, distinct and fine but well separated on terga 1-3, becoming somewhat coarser but still slightly separated at extreme sides, rather uniformly close across 4 and 5, very fine and densely crowded on 6, apical margins only slightly depressed, finely and rather sparsely punctate nearly to the rims.
MALE — Length 8-9 mm.; bluish-green; face somewhat longer than distance between eyes above; eyes very slightly convergent below; lateral ocelli subequally distant from mar-gin of vertex and each other, slightly more distant from eyes; clypeus broadly convex, somewhat produced apically, the narrow, median area of margin smooth and shining, impunctate, nearly straight; mandibles bidentate; cheeks somewhat broader than eyes; wings subhyaline, 2nd recurrent vein reaching 2nd submarginal cell much nearer apex than 1st does to base; tarsal segments slender, simple and unmodified, anterior margin of hind basitarsus with a very low, subapical tubercle or angle; mid spurs brownish- testaceous, hind spurs more fuscous; pubescence entirely whitish, rather copious on face, cheeks below, over most of thorax, and on front and middle legs; punctures quite deep and distinct, rather close but not crowded on vertex and cheeks, and on face between antennae and ocelli, becoming densely crowded below antennae and over clypeus; punctures of scutum quite close but not crowded, slightly separated in center of disc, scutellum with a very narrow, median, impunctate line, otherwise closely punctate; punctures of pleura almost crowded; lateral faces of propodeum rather smooth but minutely roughened, the metapleura largely shining and impunctate, posterior face of propodeum rather dull and tessellate, punctures vague and obscure, dorsal area velvety, margin becoming very finely striate; abdominal terga shining, punctures quite deep and distinct, rather coarse and well separated toward basal margin of each tergum, becoming rather fine and irregular toward the depressed, shining and impunctate apical rims, punctures of 5 more uniformly distributed, slightly separated, those on 6 rather distinct, close at base, but becoming sparse, minute and irregular apically; tergum 6 with a shallow, median emargination, 7 quite broad and short, the median, apical emargination very shallow and obscure, hardly evident; sternum 2 largely covering 3 and 4, apical margin broadly outcurved, narrowly yellowish-hyaline, 3 with a rather narrow, median, triangular emargination which is largely filled with converging setae (fig. 33), 4 slightly produced medially toward apex, this area sparsely clothed with elongate, recurved setae, 5-8 entirely retracted, 8 broadly rounded apically, apex very narrowly emarginate medially; genital armature as shown (fig. 35).
DISTRIBUTION — Minnesota to Quebec and the New England states, south to Georgia, April to August.
FLOWER RECORDS — Brassica, Geranium, Malus, Pent stemon, Rubus, Tifoliurn and Vicia. This is recorded by Robertson (1929) on Gillenia.
