Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141.

FEMALE—Length 6 mm.; black; length and breadth of face subequal; eyes subparallel; cheeks subequal to eyes in width; process of labrum subquadrate, truncate apically; facial foveae shallow but distinct, terminating below about at level of antennae, only slightly narrower below; lateral ocelli much nearer margin of vertex than to each other; median segments of flagellum slightly broader than long; surface shining between ocelli and antennae, punctures very fine and rather widely separated, becoming somewhat closer just below antennae, but more sparse medially, laterally and on clypeus where they become progressively coarser toward the apical margin, those on cheeks fine, shallow and obscure; pubescence of head short and thin, entirely pale, somewhat yellowish on vertex, that on scutum short and rather dense, yellowish, becoming more whitish laterally and beneath, tegulae yellowish-hyaline; wings subhyaline, veins and stigma brownish to piceous, recurrent veins entering 2nd submarginal cell subequally distant from base and apex; legs dark except for a small, basal, yellow spot on front and middle tibiae; spurs yellowish; surface of dorsum of thorax shining between the uniformly fine but deep, distinct and close punctures, those on scutellum slightly coarser than those on scutum; pleura less shining, punctures somewhat coarser but very shallow and obscure; apical margins of abdominal terga broadly and deeply depressed, these areas smooth and shining, somewhat reddened, discs of terga very finely punctate, punctures close basally, becoming sparse and very minute and obscure toward the apical depressed rims, discal pubescence short, thin and sparse toward base, becoming longer and more conspicuous apically, forming a quite dense, pale brownish, apical fimbria on tergum 5.

MALE—Length 5 mm.; black; length of face subequal to distance between eyes above; eyes somewhat convergent below; clypeus except apical margin at extreme sides, process of labrum, base of mandibles and areas between clypeus and eyes, yellow maculated, upper border of lateral maculae terminating at about upper margin of clypeus; cheeks very slightly narrower than eyes; process of labrum quadrangular, slightly broader than long, apex broadly truncate; facial foveae narrow, elongate, distinct, terminating about at level of antennae; lateral ocelli considerably nearer margin of vertex than to each other; median segments of flagellum considerably broader than long; face below anterior ocellus closely and rather finely punctate, punctures becoming somewhat coarser and more sparse above on vertex laterally and on lateral areas of face, very fine and distinctly separated below antennae, becoming somewhat coarser and rather sparse on maculated areas; cheeks shining, minutely and sparsely punctate; pubescence of bead and thorax short but rather dense, pale ochraceous on vertex and dorsum of thorax, becoming whitish laterally and beneath; tubercles yellow; tegulae yellowish-hyaline; wings lightly infuscated, veins and stigma brownish to piceous, recurrent veins entering 2nd submarginal cell subequally distant from base and apex; femora yellow at extreme apex, otherwise blackish, front tibiae dark posteriorly, otherwise yellow; mid tibiae dark, except for basal and apical yellow areas; hind tibiae dark, over apical half, basal half and tip yellow; tarsi and spurs entirely yellow; dorsum of thorax shining between fine, deep, distinct and quite close punctures, those on scutellum slightly coarser than those of scutum; pleura not so shining, punctures shallow and obscure, rather sparse; apical margins of abdominal terga evenly and rather deeply depressed, these areas shining, not much reddened, punctures of discs of terga close, deep and fine basally, becoming quite sparse and more obscure toward depressed apical margins, discal pubescence very short fine and obscure, entirely pale; sternum 6 with a deep, triangular, median emargination; wings of sternum 7 small, triangularly angulate laterally, with a narrowly rounded tip, bearing only one or two very short, inconspicuous setae; gonostyli flattened, rather narrow, tip slightly incurved, gradually narrowed to a slender apex, bearing a dense fringe of rather short setae on outer margin; penis valves very slender, about attaining tips of gonostyli.

DISTRIBUTION—Quebec to Illinois, south to Florida and Texas; May.
