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 16 mm.; black, including legs, tegulae yellow; eyes parallel; clypeus somewhat swollen medially; apical margin broadly and very slightly incurved; mandibles quite broad apically, 4-dentate, inner teeth very low, with no bevelled edges evident (fig. 59); space between lateral ocelli and eyes about half that between ocelli and margin of vertex; cheeks slightly narrower than eyes; punctures of vertex quite deep and distinct but close and rather fine, becoming minute and close on cheeks above, somewhat more coarse and sparse below; punctures fine and densely crowded on face beneath dense pubescence, supraclypeal area very finely but somewhat more distinctly punctate, clypeus with
narrow, median, impunctate line, quite deeply and somewhat more coarsely and closely punctate on each side; pubescence of head and thorax bright yellow to rather deep fulvous, very dense at sides of face and around and above antennae, with a dense tuft above anterior ocellus, vertex and cheeks quite short pubescent, becoming somewhat longer on cheeks below, short and dense over most of thorax, becoming somewhat paler below and almost whitish on propodeum; scutum and scutellum very finely, distinctly and closely punctate beneath dense pubescence, punctures pleura slightly coarser, uniform and close, propodeum somewhat smoother, punctures exceedingly minute, very close on posterior face; all basitarsi very slender and very much shorter than their tibiae; tegulae shining, with minute and rather close punctures; wings lightly infuscated, veins piceous; abdominal terga 2-4 slightly depressed across base, basal margin of this impression distinct but hardly carinate, apical margin of terga depressed, densely and completely fasciate, discs of 1 and 2 densely covered with fulvous pubescence that obscures the surface, that on the following terga much thinner and shorter, largely pale on 3 and 4, but 4 with numerous, sub- erect, black hairs over apical portion, 5 liberally beset with suberect, black hairs; punctures on the more basal terga minute and close, becoming somewhat more distinct on the more apical terga, well separated but minute on 4 and 5; tergum 6 nearly straight in profile, with very short, suberect hairs visible toward base, quite densely covered with appressed, blackish tomentum, surface barely visible, very finely and densely punctate; sternum 6 well covered with short, black, scopal hairs, scopa otherwise yellowish-white, sterna deeply and distinctly punctate, punctures rather coarse and well separated on 3-5, apical margins narrowly yellowish-hyaline, and sternum 5 with a rather distinct, white, apical fascia.
MALE—Length 13 mm.; black including legs, tegulae yellowish; eyes parallel; clypeal margin about straight beneath the dense beard; mandibles 4-dentate (fig. 59), inferior margin with a very slight angle near base; apical segment of flagellum slender; space between lateral ocelli and eyes about half that between ocelli and margin of vertex; cheeks slightly narrower than eyes; punctures of vertex and cheeks fine and close but quite deep and distinct, becoming slightly coarser on cheeks below, face and clypeus with very fine, close punctures beneath dense pubescence; pubscence of head and thorax entirely pale, that on face below antennae pale yellowish, dense and elongate, becoming more fulvous above, with a dense transverse brush above anterior ocellus, hairs on vertex somewhat shorter, fulvous, becoming more elongate and whitish on cheeks below; venter of thorax rather thinly whitish pubescent, becoming denser but rather short above, more fulvous in color, entirely deep fulvous, rather short but erect on scutum and scutellum, that on propodeum somewhat thinner and more whitish; punctures of scutum somewhat more distinct and coarse medially, somewhat finer and densely crowded anteriorly and laterally, very fine and densely crowded on scutellum and axillae; pleura somewhat shining, punctures quite deep and distinct, fine and very close above, becoming somewhat coarser and somewhat more widely separated below; propodeum rather smooth, punctures minute and obscure, quite close on posterior face; front coxal spines very short, subtriangular, with narrowly rounded tip, coxae thinly white pubescent anteriorly, spines rather densely long pubescent posteriorly; front tarsi dark, entirely simple; mid tibial spurs well developed; tegulae very minutely and closely punctate; wings subhyaline, veins brownish-piceous; abdominal terga 2-5 shallowly depressed across base, basal margin of depressions distinct but hardly carinate, apical margin of terga depressed, with complete, dense, apical fasciae,
and 2 densely covered with fulvous pubescence, hiding surface, that on 1 copious and elongate, short on 2, apical fasciae yellow, discal pubescence of 3 much shorter and thinner, largely fulvous, but with a few black hairs apically, and 5 with conspicuous, suberect, black hairs, overlying in part the white fasciae; punctures very fine and very close on the more basal terga, becoming somewhat more coarse and distinct but still quite close on the more apical terga; tergum 6 irregularly and rather finely rugoso-punctate, with conspicuous, long and erect, black, seta-like hairs, carina very low, with a very slight, median emargination, apical margin entirely lacking teeth; sterna 1-4 exposed, quite closely and deeply punctate, finely so on the basal sternum, becoming slightly coarser on the more apical plates, apical margins narrowly yellowish-hyaline, prominantly fringed with whitish pubescence; setose area of sternum 5 broad and expansive, occupying much of the plate, median and apical areas largely bare, setae very abruptly and broadly dilated at tips, apical margin of sternum quite deeply, triangularly emarginate medially, each side quite broadly outcurved (fig. 61); setose area of sternum 6 not divided medially, occupying most of apical half of plate, setae quite robust, directed apically, considerably dilated at tips, plate without an apical lobe; tergum 7 transverse, largely hidden; gonocoxites strongly compressed above base, slightly sinuate, slender and accuminate at tip, with a proniinant fringe of plumose bristles on inner surface over apical half, the more basal setae more elongate (fig. 62).
DISTRIBUTION—This is an Old World species, widely distributed through the Ethiopian and Oriental regions, and has been established in the West Indies since the days of the slave trade. Within recent years it has appeared in the southern end of Florida, but may or may not have become well established.
