FEMALE—Length 7 mm.; entirely black; face much longer than distance between eyes above; eyes very slightly convergent below; lateral ocelli subequally distant from margin of vertex and each other, slightly more distant from eyes; clypeus broadly convex, apical margin shallowly concave medially, minutely crenulate on each side; mandibles slightly broadened apically, with a low, subapical tooth which is considerably removed from the inner angle; cheeks subequal to eyes in width; wings hyaline basally, becoming lightly infuscated apically, veins and stigma piceous; tegulae piceous, smooth and shining; legs entirely black, spurs pale yellowish; pubescence very short and thin, entirely pale, somewhat more copious at sides of face, cheeks below, around tubercles and wing bases; abdominal terga 1-5 with narrow, entire, whitish, apical fasciae, discal pubescence hardly evident toward base, becoming somewhat more distinct toward apex; scopa entirely pale; punctures of head and thorax very coarse, close and distinct, but clypeus and face below antennae more finely rugoso-punctate, thoracic punctures more definitely separated but still very close; posterior face of propodeum sharply differentiated from the narrow, dorsal, pitted area and lateral faces by a distinct marginal carina, surface rather dull, closely but rather finely punctate; punctures of abdominal terga not quite so coarse, well separated on discs of 2-4 medially, but becoming closer and coarser toward sides, quite close over most of 5, 6 more finely and densely punctate; abdominal sterna yellowish-hyaline apically, discs closely and deeply punctate, rather finely so toward apical margin of each, those on 6 quite close and fine but distinct.
MALE—Length 7 mm.; entirely black; face much longer than distance between eyes above; eyes slightly convergent below; lateral ocelli subequally distant from margin of vertex, eyes, and each other; apical margin of clypeus straight, the thickened edge smooth; mandibles bi-dentate; cheeks somewhat narrower than eyes; wings hyaline basally, becoming lightly infuscated apically, veins and stigma piceous; tegulae piceous, smooth and shining, with only microscopic punctures evident; legs largely black, spurs yellowish, front femora and tibiae ferruginous along upper and anterior surfaces; abdominal sterna 1 and 2 exposed, sternum 1 produced medially nearly to margin of 2, this area rounded or obscurely angulate, with considerable short and dense pubescence at center; sterna 3-8 retracted, form as shown (fig. 15); genital armature as shown; pubescence very short, thin, entirely pale, quite dense along sides of face, on cheeks below and over lateral portions of clypeus; scutellum with a rather conspicuous, erect fringe of whitish hairs posteriorly; terga 1-4 with narrow, whitish, apical fasciae, that on 1 rather widely interrupted medially, 5 not fasciate; punctures very coarse, close and deep over most of head and thorax, but face below antennae more finely rugoso-punctate, clypeus very finely so apically; punctures of abdominal terga not quite so coarse, very close in large part, tergum 5 and median area of 6 rather densely rugoso-punctate but these becoming more distinct laterally and toward apex.
DISTRIBUTION — Illinois to Maine and New Brunswick, south to Florida, March to October.
FLOWER RECORDS — Anthemis, Bidens, Chrysopsis, Erigeron, Galax, Helenium, Ilex, Jussiaea, Oenothera, Polygonum, Senecio, Solidago and Stokesia. Robertson (1929) includes a long list of plants visited by Neotrypes truncatus MS. This was never described, but he indicates that there was some confusion with N. productus (= vanolosa) as to the identity of the females. It seems probable, therefore, that leavitti is the species he had before him.
