(Figs. 134, 135)
Triepeolus monardae Mitchell 1962: 475, Fig. 112, [Holotype: U. S. National Museum of Natural History No. 75246; male, Wilmington (New Hanover Co.), North Carolina; 12 September 1932].
Description.—Length ca. 15–18 mm; ITW 2.9–3.5 mm. Integument black, with red on medially on mandible; brown on outer F1; dorsum of mesosoma and metasoma with bands of pale yellow setae. Clypeus with strong midline and weak larger punctures, densely covered with white setae in males. Paramedian band clearly separated from other pale setae on mesoscutum in both sexes. Scutellum strongly bigibbous; axillar spine strongly pointed, weakly incurved, surpassing midpoint of scutellum. Mesepisternum with short, erect, simple setae; punctures nearly contiguous to separated by up to 0.5 puncture diameter; integument between punctures raised; with dense, white, branched setae on dorsal third (sparser on hypoepimeron in females). T1 discal patch widely rectangular/trapezoidal; T2 with LLB forming acute angle with ATB. Female: Pseudopygidial area subovate, with uniformly shining, dark, “glossy” setae; S2–S3 (sometimes also S4) with white setae on apicolateral margins; S5 not downcurved. Male: Pygidial plate relatively wide, keyhole shaped, with distinct basal transverse ridge; S2–S3 with white apical bands of setae; S4–S5 with apical fringes setae brown (paler brown with white laterally on S4, sometimes with small area of white setae on S5).
Comments.—This species is distinctive for its large size and pattern of pale setal bands on the metasoma.
Distribution.—USA: Florida, Georgia, North Carolina.
Floral Records.—Monarda punctata L., white goldenrod (= Solidago bicolor L.).
Seasonal Records.—28 August to 12 September.
Specimens examined.—3 female, 3 male (RALEIGH, NEW YORK, WASHINGTON D.C.).

MALE—Length 16 mm.; mandibles and apical tarsal segments somewhat reddish, otherwise entirely black; basal segment of flagellum considerably shorter than segment 2, median segments slightly longer than broad; space between margin of vertex and lateral ocelli much less than their diameter; cheeks very narrow, little more than one third width of eyes, still narrower below, posterior margin subcarinate; median length of labrum about half the breadth, with a pair of minute, subapical denticles medially; posterior margin of scutellum broadly outcurved, deeply impressed medially, free part of axillae robust and elongate, nearly attaining posterior transverse line of scutellum (fig. 11) wings lightly infuscated, with the usual three submarginal cells, veins piceous; face below antennae quite densely silvery tomentose, more thinly so across apical half of clypeus, face above with more elongate, erect and rather thin pubescence; cheeks very finely and rather thinly whitish tomentose; margin of pronotum densely pale yellowish tomentose, this continuing around tubercles, upper half of pleura quite densely yellowish tomentose; scutum with a pair of anterior, elongate patches of yellowish tomentum reaching slightly beyond mid point on each side of midline; lateral margins of scutum, scutello-mesothoracic suture, metanotum and adjacent posterior face of scutellum densely pale yellowish tomentose, with a quite dense tuft of elongate pale hairs on each side posterior to wing bases; posterior face of propodeum quite densely pale tomentose, especially above and laterally, triangle largely bare; anterior face of basal abdominal tergum largely pale yellowish tomentose, and with a subapical fascia, these rather broadly united laterally, the fascia slightly interrupted medially and slightly removed from apical rim, the resulting black tomentose patch very broadly transverse; tergum 2 with a broad, subapical, yellowish fascia and with a quite large patch of yellowish tomentum on each extreme side that extends from the fascia to the base; terga 3-5 with subapical, transverse fasciae which are rather widely removed from apical rims, 6 with an apical fascia; tegulae minutely and very closely but distinctly punctate throughout; punctures of face below ocelli deep, distinct and rather coarse but quite close, rather sparse laterad of each lateral ocellus, finer and quite close across vertex, fine and slightly separated on cheeks; punctures of scutum deep and distinct but rather fine and close, slightly separated near midline over posterior half; scutellum and axillae densely and finely rugoso-punctate, quite dull; pleura below rather irregularly and closely punctate, but with a few narrow, shining interspaces evident, becoming densely and more finely rugose above, beneath pale tomentum; punctures of discs of abdominal terga beneath the black tomentum very minute and close, quite uniform; sterna 2 and 3 quite conspicuously whitish fasciate apically, 4 and 5 with subapical fringes of elongate, apically curved, brownish hairs; pygidial plate strongly elevated above disc of tergum 7, with a rather conspicuous, submedian, transverse ridge, apical part beyond ridge about as broad as long, broadly rounded, margin carinate, surface rather smooth, the more basal area densely and finely rugose.
