Overview
Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.

MALE—Length 6.5 mm.; lateral ocelli slightly nearer margin of vertex than to each other; cheeks nearly equal to eyes in width, posterior margin not carinate; antennal scape only slightly swollen, apex rather deeply excavated, partially enclosing pedicel, longer side of basal segment of flagellum slightly shorter than segment 2, median segments slightly longer than broad; mandibles slender and simple; wings hyaline, very faintly infuscated along apical margin, with the usual three submarginal cells, 2nd and 3rd nearly equal anteriorly, veins testaceous, basal vein interstitial with transverse median; tegulae shining, punctures minute, scattered and rather sparse; posterior margin of scutellum rounded, not appreciably depressed or grooved; front coxae not spinose; hind femora unmodified; clypeus except upper margin, labrum, mandibles except tips, small lateral facial maculae, and anterior face of antennal scape, yellowish-testaceous, flagellum testaceous; head otherwise black; tubercles, tegulae, tibiae and tarsi testaceous at least in large part; spurs pale yellow, femora more piceous, becoming testaceous apically or along upper and anterior faces; thorax otherwise black; abdominal terga more or less reddish, basal tergum becoming more piceous at extreme base, terga 2-6 with more or less conspicuous, yellow maculae laterally, these extensive on apical margins of terga yellowish-hyaline, more ferruginous basally; punctures coarse, close and deep on face above antennae, on vertex and cheeks, and between antennae and clypeus below, the clypeus and lateral maculated areas with very obscure, spa1se punctures; scutum, scutellum and mesopleura coarsely and densely rugoso-punctate, lateral faces of propodeum dull, tessellate, with scattered, obscure and rather fine reticulations, posterior face more fully rugose, triangle impunctate but becoming rather coarsely striate along upper margin; punctures of abdominal terga minute, rather close throughout, barely visible toward base of tergum 1, evident but very fine on the following terga, minute and close over basal areas of each disc, becoming hardly visible apically; pubescence entirely pale, short but rather copious over head and thorax, hardly visible on abdomen both dorsally and ventrally; median length of pygidial plate somewhat greater than basal width, rather strongly narrowed apically, tip narrowly subtruncate and shallowly emarginate, margins carinate, surface obscurely but rather closely punctate; abdominal sterna dark; sternum 8 with a slender apical process; gonostyli of genital armature as shown (fig. 107).

TYPES—Holotype: Male, Slide Mt., Ulster Co., N. Y., June 12, 1941 (H. Dietrich). Paratypes: 1 male, Washington, D. C., May 15, 1944 (G. E. Bohart).

It seems probable that the male from Pennsylvania associated by Swenk with his subnigrocincta is this species.
