FEMALE—Length 9 mm.; black, including legs, tegulae yellowish anteriorly, spurs entirely yellow; eyes slightly convergent below; clypeal margin straight and entire; mandibles 4-dentate, a bevelled edge between the 3rd and 4th teeth; lateral ocelli considerably nearer margin of vertex than to eyes; cheeks much narrower than eyes; vertex rather dull, punctures slightly separated on each side, but otherwise densely crowded, becoming very fine and indistinct on cheeks, rather coarse just below base of mandibles; face quite densely rugoso-punctate below ocelli, becoming more distinct but very fine and close laterally, supraclypeal area with shining spaces between rather sparse punctures just above clypeus but becoming closely punctate laterally, dypeus with a rather distinct, impunctate, median line, closely and deeply punctate on each side; pubescence of face yellowish-white, rather dense but not very long around antennae, below ocelli and along inner orbits, clypeus and vertex with erect and rather sparse, yellowish hairs, cheeks densely white tomentose above, pubescence becoming more elongate and erect below; thorax with rather short, whitish pubescence laterally and posteriorly, this rather dense around tegulae and back of wing bases, somewhat more elongate propodeum; scutum with rather thin, shortbut erect, more fuscous or yellowish pubescence, becoming whitish anteriorly, scutellum with longer, erect, yellowish hairs, the scutellomesothoracic suture faintly tomentose; dorsum of thorax uniformly, densely and finely punctuate throughout; pleura somewhat shining below, punctures distinct but rather close, becoming densely crowded above; lateral faces of propodeum rather dull, surface with numerous, close but fine punctures, posterior face dull, punctures minute, close and rather vague; mid and hind basitarsi nearly as broad as their tibiae, but definitely shorter, the front tarsi quite slender; tegulae minutely and rather obscurely purictate; wings subhyaline, veins piceous; abdominal terga 2 and 3 very shallowly grooved across base, the grooves hardly carinate, apical margins of terga rather deeply depressed laterally but only slightly so medially if at all, with entire, whitish, apical fasciae, these quite dense laterally; basal tergum with rather thin, elongate, pale pubescence, discal pubescence of 2-4 very short, largely fuscous, that on 5 somewhat more elongate and conspicuous apically; punctures of terga 1-4 rather deep and distinct but fine and close, becoming somewhat more sparse toward apical margin of 5, 6 straight in profile, with numerous dark, subereet hairs visible, surface very finely and densely punctate, usually with a more or less extensive patch of pale tomentum; scopa pale yellowish or whitish on sterna 2-5, black on 6, with a few black hairs at sides of 5, punctures of sterna deep, distinct and rather close and fine, apical margins narrowly depressed, with entire, white, apical fasciae.

MALE—Length 7 mm.; black, tegulae more or less yellowish-testaceous, spurs yellow, legs largely black; eyes slightly convergent below; median third of clypeus slightly produced and shallowly incurved; mandibles 3-dentate, inferior process submedian, rather slender and acute; apical segment of flagellum slender and unmodified; lateral ocelli slightly nearer margin of vertex than to eyes; cheeks considerably narrower than eyes, still narrower below, with a small, acute tubercle just below base of mandible; vertex dull, punctures well separated on each side but densely crowded medially, very fine and quite close on cheeks, face below ocelli densely rugoso-punctate, becoming more distinctly but very closely punctate laterally, punctures minute and densely crowded below antennae and on clypeus; face with dense, yellow or yellowish-white pubescence which largely hides surface, more whitish on cheeks, somewhat yellowish and rather dense above, becoming elongate below, rather thin, erect and sparse on vertex; pubescence of thorax short, quite dense, white or yellowish laterally and posteriorly, more erect but ratherthin, either yellowish or whitish dorsally, the scutello-mesothoracic suture narrowly tomentose; dorsum of thorax uniformly, finely and densely punctate, pleura somewhat shining below, punctures distinct but quite close, becoming densely crowded above; lateral faces of propodeum relatively smooth, with only very fine and rather close punctures, posterior face dull, punctures minute, rather close above, becoming sparse below; front coxal spines rather short, subtriangular, apex narrowly rounded, quite densely pubescent, and anterior surface of coxae pubescent, more or less obscuring the spines; front tarsi dark, simple and unmodified, with a quite distinct but rather short, posterior, white fringe; front femora more or less carinate below apically, inner face of this area yellow and carinate border of the posterior face narrowly yellow, femora otherwise dark; mid and hind tarsi slender and simple; mid tibial spurs well developed; tegulae minutely and obscurely punctate; wings subhyaline, veins piceous; abdominal terga 2-5 rather narrowly grooved across base, basal margins subcarinate, apical margins of the terga rather deeply depressed, especially laterally, only obscurely so medially, 2-4 with dense, apical, whitish or yellowish fasciae; tergum 1 with rather copious, elongate and erect, yellowish or whitish pubescence, somewhat obscurely pale fasciate apically, tergum 2 with shorter but quite dense and erect pale pubescence, with some dark hairs at extreme sides, discal pubescence of 3 and 4 suberect, largely pale, very fine and obscure; tergal punctures very fine and close throughout; tergum 5 fasciate basally but not apically, rather coarsely rugoso-striate, with suberect, rather conspicuous, largely pale pubescence; tergum 6 densely pale tomentose throughout, only the median, emarginate area of the low, inconspicuous carina exposed, median teeth of apical margin inevident, lateral angles very low and obscure; tergum 7 very low, transverse, largely hidden, not at all produced medially; sterna 1-4 exposed, quite closely and finely punctate, apical margins depressed, with dense, pale, apical fasciae; setose area of sternum 5 quite limited in area, subtriangular, apical margin nearly straight, setae very fine, becoming rather elongate apically (fig. 89); sternum 6 with narrow, transverse, setose lobes on each side that are slightly separated medially, apical lobe in- evident; gonocoxites narrowed above base, compressed toward apex, somewhat abruptly narrowed just before the rounded tips which are slightly emarginate below, lacking conspicuous setae.

DISTRIBUTION — Although concinna was described from the West Indies, it belongs to an Old World group and probablywas introduced from Africa during the early part of the nineteenth century. It appeared in the United States after World War II, and is now distributed from Florida and Alabama to Pennsylvania and Ohio in the East, and established as far west as California. It was first believed by this writer to be argentata, which explains the misidentification in the Catalog of Hymenoptera (Krombein, 1958). It is in flight from March, in Florida, to October.

FLOWER RECORDS—In North America this has been collected on Asciepias, Bidens, Melilotus and Polygonum. Megachile derelictula Cockerell (Barbados) and Megachile multidens Fox (Jamaica) are very similar to concinna and quite possibly synonymous.
