FEMALE—Length 11-13.5 mm., breadth of abdomen 4.5-5 mm.; black, including antennae and legs, spurs more piceous, apical tarsal segments becoming somewhat brownish; tegulae brownish to piceous; wings lightly infuscated, veins brownish to piceous; cheeks slightly narrower than eyes; clypeus moderately protuberant, its median length slightly greater than half the distance between eyes below; eyes very slightly convergent below; mandibles distinctly tridentate apically, the median tooth more elongate; basal segment of flagellum fully equal to segments 2-4 combined; labrum somewhat broader than its median length; surface of face dull, punctures on median area very fine and close, becoming more shallow, indistinct and rather sparse above, minute, close and indistinct on cheeks, considerably coarser, deeper and quite close on clypeus, the labrum more irregularly reticulate; scutum rather smooth but dull, punctures very shallow, obscure and very sparse medially, becoming much closer but very obscure peripherally, those on scutellum very shallow, vague and rather close; pleura dull and densely tessellate. punctures very shallow and vague, hardly evident; propodeum dull and tessellate, punctures of posterior face quite distinct and rather close, lateral faces dull but rather smooth, nearly impunctate; abdominal terga rather smooth but dull, median punctures very vague and indistinct, becoming somewhat more distinct laterally, fine and rather widely separated in general, becoming somewhat closer on tergum 5, apical margins of all rather narrowly impunctate; pygidium rather broad at base, narrowly produced apically, tip subacute; pubescence of face below level of antennae, and lower part of cheeks largely pale and quite dense, upper part of cheeks, vertex and face above antennae with erect, fuscous pubescence, a few dark hairs between antennae and eye margins below; scutellum and much of scutum with erect fuscous pubescence, that on anterior third of scutum erect and cream- colored, dense and entirely pale on pleura and propodeum; pubescence of legs pale in large part, some dark hairs on fore and mid tibiae and on tarsi beneath, hind tibial scopa whitish; basal abdominal tergum with rather thin but elongate, whitish pubescence, a few dark hairs across the disc medially; terga 2-4 with rather sparse, short, erect pubescence which is dark medially, becoming light laterally; tergum 5 quite copiously covered with rather short, dense, orange pubescence.
MALE—Length 10-12.5 mm., breadth of abdomen 4-5 mm.; black, clypeus entirely yellow, labrum largely yellow, the apical rim and spots on lateral angles above, dark; margin of supraclypeal area adjacent to clypeus very narrowly yellow, and lateral yellow maculae narrowly produced along eye margin to level of antennae; antennal scape entirely black or with small yellow maculations; legs black, apical tarsal segments becoming somewhat brownish-testaceous, spurs dull testaceous, tegulae piceous; wings subhyaline, or very faintly brownish, veins piceous to black; cheeks subequal to eyes in width; clypeus strongly protuberant, its median length somewhat greater than half the distance between eyes below; eyes very slightly convergent below; median length of labrum about two-thirds the breadth; mandibles tridentate apically; basal segment of flagellum equal to segments 2 and 3 combined; hind basitarsi slender and unmodified; median area of face finely and densely punctate, punctures becoming more shallow, sparse and obscure above, coarser and deeper below, those on clypeus slightly but not widely separated, quite obscure on the yellow surface, quite deep and distinct on labrum. becoming sparse at extreme sides; cheeks with very minute, obscure but rather close punctures, becoming somewhat deeper and more distinct posteriorly; scutum quite smooth but dull medially, with sparse, very fine, scattered punctures, becoming somewhat coarser and closer but very shallow around periphery; scutellum dull, densely tessellate, closely but very obscurely punctate; pleura tessellate, punctures very shallow, slightly separated in median area, becoming minute and sparse anteriorly where the surface is shining, especially above front coxae; posterior face of propodeum rather dull but smooth, punctures rather close and shallow, becoming more minute and indefinite on lateral faces; abdominal terga somewhat shining, punctures minute and quite close on basal tergum, more widely separated on following terga, becoming quite sparse on 3-6; pubescence of face and lower half of cheeks long and erect, pale yellowish or white, cheeks above, vertex and area below ocelli with long. erect fuscous hairs; posterior two-thirds of scutum and anterior half of scutellum with erect, rather copious, fuscous pubescence, that on thorax otherwise more whitish, entirely pale on legs; basal abdominal tergum rather copiously covered with elongate pale hairs, discs of the following terga with shorter but erect and largely dark hairs, becoming quite elongate on the more apical terga, margins of 2-5 with thin, indefinite and very narrow, apical fasciae that are widely interrupted medially, sometimes not evident; tergum 7 narrowly produced medially, this process triangularly emarginate, the resulting pair of projections rather narrowly rounded; sterna 7 and 8 and genital armature as shown (figs. 91 and 92).
DISTRIBUTION — Alberta to Maine, south to North Carolina. May to September.
FLOWER RECORDS — Medicago, Pentstemon and Salvia. Robertson (1929) also lists Blephilia, Monarda, Prunella, Rosa and Scutellaria. Typical furcata is Palearctic in distribution and does not occur in North America.
