Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.
FEMALE—Length 15.5-16 mm., breadth of abdomen 6.5-7 mm.; entirely black; wings lightly but uniformly infuscated, veins piceous to black; cheeks subequal to eyes in width; clypeus quite strongly protuberant, its median length somewhat greater than half the distance between eyes below (fig. 94); eyes very slightly convergent below; median length of labrum about two-thirds the breadth, apical margin rather broadly rounded; mandibles with a small, inner, subapical tooth; basal segment of flagellum equalling segments 2 and 3 combined in length; hind basitibial plate short and broadly rounded, tibia with an elongate, apically narrowed, densely pale tomentose area immediately beyond the plate; clypeus somewhat shining, punctures quite deep, and rather coarse, irregularly scattered and rather sparse; labrum somewhat shining, more sparsely and finely punctate; supraclypeal area narrowly shining and impunctate along mid-line, becoming very closely and finely punctate on each side, lateral surfaces of face below level of antennae closely and finely but quite distinctly punctate, becoming much more minutely and closely punctate above antennae; surface shining between eyes and ocelli, punctures minute and vague; cheeks with fine and close punctures below, these becoming more sparse and indistinct above; scutum with a median posterior area with well separated but hardly sparse, shallow punctures, scutum, scutellum and pleura otherwise very minutely and closely punctate; posterior face of propodeum somewhat more shining, punctures exceedingly minute and indistinct, lateral surfaces dull, minutely and closely punctate; abdominal terga somewhat shining. punctures minute and rather close but distinct on the more basal terga, becoming somewhat closer along lateral margins and closer on the more apical terga; pygidium elongate triangular, apex rather narrowly rounded, margins carinate; scutum, scutellum and posterior face of propodeum entirely and densely pale ochraceous pubescent, pleura with a limited area of ochraceous pubescence above, otherwise black on head, thorax and legs; basal abdominal tergum with intermixed black and light pubescence which is quite long and copious, the following terga with very short, inconspicuous, suberect black pubescence, that on the more apical terga more elongate; tergum 5 with a quite dense, black or fuscous, apical fimbria.
MALE—Length 13-14 mm., breadth of abdomen 6-6.5 mm.; black, clypeus largely yellow, with only a small amount of black on each side above, the narrow adjacent margin of supraclypeal area and rather small lateral maculations, ending narrowly on eye margin at level of antennae, yellow (fig. 94); spurs brownish-testaceous; wings subhyaline basally, becoming very lightly infuscated apically, veins piceous to black; cheeks slightly narrower than eyes; clypeus strongly protuberant, its median length somewhat greater than half the distance between eyes below; eyes very slightly convergent below; labrum broadly rounded, its median length somewhat less than basal width; mandibles with a very small, inner, subapical tooth; basal segment of flagellum about equal to segment 2 in length; punctures of clypeus quite deep and distinct but rather fine and well separated, somewhat obscure on the yellow surface, those on labrum rather close and fine medially at base, becoming sparse on the shining surface on each side, the inflexed lateral margins quite closely and finely punctate; supraclypeal area very finely and closely punctate above the maculated margin, lateral areas of face below level of antennae somewhat shining, punctures fine and distinct, slightly separated, surface above becoming very minutely and closely punctate; cheeks with very fine and close punctures below, becoming minute and indistinct above; median posterior area of scutum rather dull but smooth, with distinctly separated, scattered punctures, the scutum, scutellum and pleura otherwise very minutely and closely punctate throughout; posterior face of propodeum somewhat more shining, punctures minute and obscure, dorsal area largely impunctate medially; abdominal terga somewhat shining, punctures very fine and quite close, becoming much closer along lateral margins, and quite close on disc of tergum 6; pygidial area somewhat indefinite, the margins obscure, median length about equal to basal width, apex rather narrowly truncate; pubescence of scutum, scutellum, basal abdominal tergum and posterior face of propodeum long and copious, entirely pale ochraceous, pleura with some similar pubescence above beneath wing bases; vertex with some intermixed pale hairs below ocelli and across vertex, pubescence otherwise black on face, cheeks, pleura below, lateral surfaces of propodeum, legs entirely, and abdominal terga 2-7, very short and suberect on abdomen, hairs becoming somewhat more elongate on the more apical terga, especially at sides; sterna 7 and 8 and genital armature as shown (fig. 95).
DISTRIBUTION — Illinois to the New England states, south to Mississippi and Florida, November, January and February in Florida, elsewhere March to May.
FLOWER RECORDS — Cirsium, Lupinus, Malus, Melilotus, Prunus, Vaccinium and Vicia. Recorded by Robertson (1929) on Cercis and Dicentra.
