North Carolina Agricultural Experiment Station Technical Bulletin No. 152. FEMALE—Length 13-15 mm., breadth of abdomen 5-5.5 mm.; black, spurs pale yellowish, tegulae yellowish-hyaline; wings very lightly and uniformly infuscated, veins testaceous to piceous, recurrent veins reaching 2nd and 3rd submarginal cells subequally distant from their tips; cheeks very slightly narrower than eyes; clypeus slightly protuberant, its median length slightly less than half the distance between eyes; eyes subparallel; mandibles simple or obscurely bi-dentate apically; basal segment of flagellum not quite equaling segments 2 and 3 combined in length; tibial spurs straight and simple; punctures of clypeus coarse and close, those on labrum much finer and crowded medially, becoming rather coarse and sparse laterally; supraclypeal area rather sparsely punctate, surface laterally with rather fine and close punctures, those above antennae close across entire width of face; cheeks somewhat shining, punctures fine, slightly separated; scutum shining, median punctures quite coarse and well separated but hardly sparse, becoming fine and close around periphery; scutellum with much finer and very close punctures throughout; pleura dull, punctures fine and close throughout; posterior face of propodeum rather dull, punctures rather sparse on each side, dorsal area becoming rather coarsely rugose along upper margin, becoming more definitely striate at each extreme side, lateral faces dull, punctures rather fine, shallow and obscure; discs of abdominal terga quite closely punctate across basal areas, rather coarsely so on basal tergum, apical impressed areas shining and impunctate on 1 and 2, punctures very fine and quite sparse on 3, and rather close and minute on 4; pygidium subtriangular, with narrowly rounded apex; pubescence copious and elongate, entirely pale ochraceous on head, largely so on thorax, but with a few darker hairs in center of scutum posteriorly; legs largely pale pubescent basally, becoming somewhat darker apically, brownish on front tarsi beneath and on outer surface of mid tibiae, that on basitarsi more fuscous, hind tibial scopa fuscous to blackish; basal abdominal tergum with rather copious, erect, pale ochraceous pubescence basally, disc with very short, subappressed, blackish pubescence toward each side but largely bare medially; following terga with only very short, inconspicuous, subappressed, dark pubescence, becoming somewhat brownish apically on tergum 5, fuscous on each side of tergum 6. MALE—Length 10.5-13.5 mm., breadth of abdomen 4-5 mm.; black, the clypeus and lab- rum entirely yellow, mandibles entirely black, legs black, apical tarsal segments becoming more testaceous, spurs pale yellowish, tegulae yellowish-hyaline; wings subhyaline, veins pale testaceous to piceous, recurrent veins reaching 2nd and 3rd submarginal cells sub- equally distant from apex; cheeks slightly narrower than eyes; clypeus slightly protuberant, its median length slightly greater than half the distance between eyes; eyes subparallel; mandibles simple or obscurely bi-dentate at apex, becoming more or less testaceous apically; shorter side of basal segment of flagellum only very slightly longer than pedicel, segment 2 about five times longer; tibial spurs straight and simple; clypeal punctures quite coarse and deep, rather close along upper margin, becoming more definitely but not widely separated below and laterally, those on labrum much finer and quite close, becoming somewhat more sparse at extreme sides; supraclypeal area dull, rather irregularly and sparsely punctate, lateral areas below antennae with quite close and fine punctures, those above antennae very close throughout; cheeks somewhat shining, punctures shallow but fine and rather close; median posterior area of scutum shining, rather coarsely punctate, punctures well separated but not sparse over a limited area, becoming finer and quite densely crowded over anterior half and more narrowly on lateral and posterior margins; scutellum shining anteriorly, punctures rather fine and close, becoming crowded laterally and posteriorly; pleura dull, punctures ‘very fine and close throughout; posterior face of propodeum rather dull, punctures shallow but rather close and irregular, dorsal face becoming more rugose along upper margin, striate at extreme sides, lateral faces closely and finely punctate; abdominal terga somewhat shining, punctures rather deep and distinct, rather coarse on basal tergum, well separated medially, becoming much finer and closer laterally, and much more sparse toward the very narrow, impunctate, apical margin; apical impressed areas of terga 2-5 well punctured, but punctures somewhat more sparse than on basal areas, apical margins very narrowly impunctate; tergum 6 very finely and rather densely punctate throughout; pubescence of head, thorax and basal abdominal tergum long, copious and erect, pale ochraceous, becoming rather bright fulvous on thorax above, and legs entirely pale pubescent; tergum 2 with an intermixture of very short, dark and light hairs across basal half, forming an obscure, pale pruinose band, apical half covered with suberect, rather elongate, black hairs; terga 3-6 with erect but rather short black hairs across basal areas, the impressed apical margins bearing some thin pale tomentum that forms obscure, barely evident, thin fasciae, apical margin of 6 with a fringe of intermixed light and dark hairs; median length of pygidial plate considerably greater than basal width, margins carinate, converging toward the rather narrowly rounded apex; sterna 7 and 8 as shown (fig. 89); genital armature much as in atriventris (fig. 88), but gonostyli short pubescent toward base. DISTRIBUTION — Missouri to Ohio, Virginia and Florida, April to June. FLOWER RECORDS — Batodendron, Diospyros, Elea gnus, Linaria, Melilotus, Pentstemon, Rubus and Stachys. Robertson (1929) records rosae also on Asclepias, Blephilia, Cornus, Dianthera, Geranium, Houstonia, Hydrophyllum, Iris, Monarda, Rosa and Trifolium. Identification Extracted from: Charles Robertson (1900). Some Illinois Bees. Trans. Acad. Sci. Of st. Louis. Female. Closely resembles the preceding form, but is smaller, the apical half of the second abdominal segment shining and impunctate, the tibial scopa more nearly surrounding that joint, less limited to the exterior of the joint.
