Overview
Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141.

FEMALE—Length 8 mm.; head and thorax piceous to blackish, basal segment of abdomen bright ferruginous; length and breadth of face subequal; eyes very slightly convergent below; median and upper portion of clypeus, lower half of supraclypeal area and adjacent lateral areas yellow maculated; mandibles yellow at base, reddish apically; labrum dark; cheeks subequal to eyes in width; process of labrum broad, quadrangular, shining; facial foveae shallow, rather broad above, accuminate below, terminating at about mid point of inner margin of eye; space between lateral ocelli and margin of vertex subequal to distance between them; median segments of flagellum very slightly shorter than their width; punctures deep, distinct, rather fine and close on upper part of head and on cheeks; becoming quite sparse on maculated areas below antennae; pubescence of head and thorax very short, thin and obscure, entirely pale; tubercles bright yellow; tegulae pale testaceous-hyaline, with a small, anterior, yellow spot; front and mid tibiae yellow over basal two-thirds, dark apically; spurs ferruginous; wings lightly infuscated, somewhat more darkly so apically, veins and stigma pale ferruginous; punctures of dorsum of thorax fine and close, but quite deep and distinct, surface somewhat shining; pleura relatively dull, punctures close and rather coarse anteriorly, but becoming fine, shallow and obscure posteriorly; apical margins of abdominal terga quite broadly and deeply depressed, these areas pale yellowishhyaline, contrasting sharply with the darker discs of terga 2-5, discs finely, closely and deeply punctate, discal pubescence short, rather obscure, somewhat more dense along basal margins of terga 2 and 3, more erect and conspicuous on tergum 5, forming a quite dense, apical, pale brownish fimbria; venter of abdomen with thin, erect, pale pubescence.

MALE—Length 8 mm.; head and thorax piceous to black, with yellow maculae, abdomen mainly ferruginous; face slightly longer than distance between eyes above, eyes slightly convergent below; labrum, mandibles and lower portion of face entirely yellow, upper border of this area forming a straight line at level of antennae; scape yellow maculated; cheeks much narrower than eyes; process of labrum broad, subquadrangular, lower margin very slightly curved; facial foveae very small, narrow and elongate but distinct; space between margin of vertex and lateral ocelli about equal to distance between ocelli; median segments of flagellum about as long as broad; punctures of head above deep and distinct, fine and rather close but not crowded, becoming slightly more sparse on cheeks below and on lower maculated area of face; pubescence of head and thorax very short but rather dense, not at all obscuring surface, entirely pale ochraceous; tubercles and an anterior spot on tegulae yellow, tegulae otherwise pale yellowish-hyaline; wings lightly infuscated, somewhat more darkly so apically, veins and stigma pale ferruginous; legs mostly yellow except for basal half of front femora and posterior half of hind femora, hind tibiae somewhat darkened apically; spurs yellow; dorsum of thorax shining between deep and distinct but fine and close punctures, pleura somewhat shining, punctures coarser and more widely separated but not sparse; apical margins of abdominal terga quite deeply but narrowly depressed, these areas yellowish-hyaline, discs ferruginous, quite closely, deeply and finely punctate, the more apical terga more or less infused with blackish, discal pubescence very short and inconspicuous, entirely pale ochraceous; apical margin of sternum 6 rather deeply incised medially; wings of sternum 7 very narrow and elongate, abruptly recurved at tip; sternum 8 elongate triangular, tip rather broadly rounded; gonostyli rather robust, straight and simple, bearing an elongate fringe of short setae ventrally, slightly exceeding penis valves.

DISTRIBUTION — Pennsylvania and New Jersey to North Carolina and Georgia; August and September.

FLOWER RECORDS — Monarda punctata is the only host plant on which this has been collected.

The typical form of abdominalis occurs in Texas and Kansas, and differs from this eastern form in the female, in having the scutellum, metanotum, propodeum in part, and most of the abdominal terga ferruginous.
