North Carolina Agricultural Experiment Station Technical Bulletin No. 152. FEMALE—Length 17-18 mm.; black; length of face about equal to distance between eyes above; eyes slightly convergent below; facial protuberance below antennae prominant, projecting at right angles from surface of face, slightly bowed in facial view; clypeus quite flat, shining and sparsely punctate, apical margin straight, with a prominant silvery fringe; cheeks somewhat broader than eyes; mandibles 3-dentate, median tooth more prominant than the others; labrum densely ochraceous pubescent beyond the basal, transverse ridge which is emarginate medially; pubescence of head entirely pale, quite dense around antennae and along inner orbits, thin elsewhere, rather elongate on cheeks below; punctures fine and close on vertex medially, becoming somewhat more widely separated laterally, somewhat coarser and more distant on the shining cheeks below; dorsum of thorax dull, densely rugose, finely so on scutellum and on scutum posteriorly, becoming rather coarsely aciculate anteriorly; pleura distinctly punctate, closely and quite deeply so above, becoming more coarsely and more widely separated but not sparse below; propodeum relatively smooth but rather dull, punctures very shallow and obscure; tegulae piceous, quite smooth but rather dull, not noticeably punctate; wings subhyaline, veins and stigma piceous; hind tibiae coarsely aciculate, the fore and mid tibiae quite deeply, distinctly and closely punctate, acieulate along posterior margin toward apex, femora shining, quite sparsely punctate; thoracic pubescence very short and inconspicuous above, more dense and elongate laterally and beneath, largely whitish; whitish and quite copious and elongate on basal segments of legs, the basitarsi rather prominantly fringed, more or less fuscous beneath and on hind tarsi; spurs testaceous; abdominal terga shining, punctures on basal terga very minute if at all evident medially, becoming more distinct but fine and close laterally, those on the more apical terga becoming coarser and more sparse; terga 2-5 with white, apical fasciae, these widely interrupted on 2 and 3, entire and very dense and conspicuous on 4 and 5, 6 with a dense covering of coarse, blackish pubescence which nearly hides the pygidial spine, ventral scopa pale ochraceous, sterna with thin, entire, white, apical fasciae, but that on sternum 5 quite dense and conspicuous. MALE—Length 15-16 mm.; black; face considerably longer than distance between eyes above; eyes rather strongly convergent below; face below antennae somewhat swollen but not protuberant, quite densely punctate; clypeus slightly convex, densely rugoso-punctate, median portion of apical margin quite straight; labrum with a quite robust, median, elongate spine at base just below margin of clypeus; cheeks subequal to eyes in width; face above antennae very closely but rather finely punctate, punctures quite deep and distinct, quite dense on cheeks throughout; pubescence of head entirely whitish, quite dense around antennae, along inner orbits and across apical margin of clypeus, rather thin above, quite elongate and copious on cheeks below; dorsum of thorax densely rugosopunctate, finely so on scutellum and over most of scutum, but this becoming somewhat more distinctly punctate anteriorly; pleura quite closely and finely punctate beneath rather dense pubescence; propodeum rather smooth, punctures fine and rather shallow except in dorsal area; pubescence of thorax entirely whitish, except that there is some faint yellowing on scutum and scutellum, quite dense and elongate laterally and on propodeum, largely whitish on legs, quite dense on anterior femora and on the apical segments, as also on mid tibiae; femora and tibiae rather closely but quite distinctly punctate, not to any marked degree aciculate; spurs testaceous; tegulae piceous, rather densely pubescent anteriorly and along inner margin, not noticeably punctate; wings subhyaline or faintly infuscated, veins and stigma piceous; abdominal terga somewhat shining, the more basal terga minutely and rather obscurely punctate medially, punctures becoming more distinct but fine and close laterally, those on 4 and 5 somewhat coarser and more widely separated medially, but becoming close laterally, and close over entire extent of 6; pubescence entirely pale on basal tergum, but discal pubescence on the following terga more or less blackish, very short and inconspicuous medially, becoming more noticeable toward extreme sides; terga 2-6 with white, apical fasciae, these more widely interrupted on the more basal terga, entire on 5 and 6; abdominal sterna entirely pale pubescent, the apical fasciae very narrow and obscure; sterna and 8, and genital armature as shown, (fig. 2). DISTRIBUTION—North Carolina to Florida and Texas, March to July, but as early as January in Florida. FLOWER RECORDS—Opunti is the principal flower upon which this depends for pollen, but it has been collected also on Cirsium, Helianthus, Ilex, Pontederia and Rudbeckia.
