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 14-18 mm., breadth of abdomen 5-6.5 mm.; black, the mandibles over basal half, labrum, and apical margin of clypeus dull testaceous, flagellum beyond segment 2 brownish-testaceous beneath, black above, tegulae testaceous, and apical tarsal segments becoming testaceous; wings quite uniformly pale brownish, veins brownish to piceous; apical margin of tergum 1 narrowly testaceous; median length of clypeus somewhat greater than half the distance between eyes below; eyes subparallel; basal segment of flagellum nearly one and a half times length segment 2, the latter considerably longer than broad; clypeus dull and tessellate, punctures rather shallow, well separated, becoming finer and very close toward the narrow, impunctate, apical rim, those on labrum closer and deeper; face above antennae more shining, median punctures quite coarse, deep and distinct, becoming exceedingly minute, barely distinguishable between eyes and ocelli; scutum and scutellum with moderately coarse and deep, subcontiguous punctures, pleura more coarsely punctate, punctures well separated in part, surface smooth and shining; propodeum posteriorly dull and densely tessellate, rather shallowly punctate, dorsal surface subreticulate, lateral faces shining anteriorly and below, the punctures obsolescent; dorsal surface of basal abdominal tergum coarsely, deeply and rather closely punctate across basal half, punctures approaching apical margin on each extreme side, apical half of disc rather smooth, punctures inevident; terga 2 and 3 dull, very finely, closely and obscurely punctate across base, broad apical areas smooth and microscopically punctate; terga 4 and 5 quite densely rugose or reticulate across base; pygidium subtriangular, apex rather narrowly rounded; pubescence of head entirely pale ochraceous, scutellum and posterior half of scutum with short fuscous pubescence, the scutello-mesothoracic suture densely whitish pubescent, thorax otherwise pale ochraceous pubescent; pubescence of legs pale ochraceous large part, scopa whitish-yellow, hairs quite densely plumose apically, front basitarsi with some brownish-fuscous pubescence on outer surface; abdominal tergum 2 with a transverse, basal, yellowish-white fasciae, 2 and 3 with lateral, oblique, whitish fasciae that are more or less separated medially; apical half of tergum 4 densely covered with whitish tomentum, somewhat thinner medially, the more basal areas of these terga with obscure, subappressed, dark pubescence, a few elongate hairs overlying the fasciae; tergum 5 with rather dense, black pubescence basally, more brownish apically, forming a dense apical fimbria.
MALE—Length 14-17 mm., breadth of abdomen 5.5-6.5 mm.; black, the entire clypeus, labrum and basal half of mandibles bright yellow, mandibles piceous apically but with an outer, oblong, orange spot; antennal flagellum brownish-ferruginous beneath, becoming somewhat paler toward base, blackish above; tegulae testaceous, wings uniformly pale brownish or yellowish, veins piceous; apical tarsal segments becoming testaceous, spurs pale yellow; median length of clypeus two- thirds distance between eyes below; eyes very slightly convergent below; segment 2 of flagellum nearly three times length of shorter side of segment 1; punctures of lateral areas of face and around antennae fine but close, deep and distinct beneath the pubescence, vertex becoming smooth and shining between eyes and ocelli, punctures hardly visible, those on clypeus somewhat coarser but very obscure, quite close, coarse, deep and distinct on labrum; scutum, scutellum and pleura with coarse, deep and close punctures, interspaces more or less shining, those on pleura somewhat coarser; propodeum dull and tessellate posteriorly, with rather coarse and close punctures, dorsal face coarsely rugoso-punctate, lateral faces becoming smooth and shining anteriorly and below, the punctures obsolescent; dorsal surface of basal abdominal tergum coarsely, deeply and rather closely punctate across basal half, punctures approaching apical margin on each extreme side, apical half of disc rather smooth, punctures inevident; terga 2 and 3 dull, very finely, closely and obscurely punctate across base, broad apical areas smooth and only microscopically punctate; terga 4 and 5 quite densely rugoso-punctate across base, apical areas with only minute, obscure and hardly visible punctures; pubescence of head entirely pale ochraceous, fuscous on scutellum and posterior half of scutum, the scutello-mesothoracic suture with some fine, pale yellowish, suberect hairs, thorax otherwise with pale ochraceous pubescence, that on legs pale ochraceous to whitish; basal half of abdominal tergum 1 entirely and quite densely pale ochraceous pubescent, apical half practically bare, with only a few dark, subappressed hairs toward each extreme side, terga 2-4 with somewhat oblique transverse whitish fasciae which are more or less widely interrupted medially, tergum 2 with a basal, transverse, white fascia, a narrow intervening area with short fuscous pubescence; basal areas of 3 and 4 with dark, appressed pubescence and scattered, erect, blackish hairs, apical areas of these terga bare; terga 5 and 6 largely black pubescent (pale in some specimens), 5 with a more or less evident, transverse, whitish fascia, usually rather widely interrupted medially, the tergum with a low angle at each extreme side; tergum 6 with a pair of robust lateral spines; median length of pygidial plate about two-thirds basal width, strongly narrowed apically, with a slight notch on each side toward the rather broadly truncate apex; sterna 7 and 8 and genital armature as shown (fig. 79).
DISTRIBUTION—Texas to Florida and North Carolina, July to October.
FLOWER RECORDS—Chrysopsis, Helenium, Helianthus and Kuhnistera. LaBerge (1956) also lists Aster, Gaillardia and Vernonia.
