FEMALE-Length 4 mm.; head and thorax black, abdominal segments 1 and 2 entirely ferruginous, 3rd becoming darkened apically, following segments piceous; head nearly as long as broad; eyes only very slightly convergent below; clypeus very slightly convex; labrum about as long as broad, quite evenly rounded, yellowish-testaceous except for the somewhat darker base; mandibles quite slender, with a barely discernible, inner, subapical tooth, color testaceous, becoming ferruginous apically; antennae black basally, becoming brownish apically, basal segment of flagellum broader than long, about equal in length to pedicel, 2nd segment not much longer, 3rd and following segments very slightly longer but hardly longer than broad; lateral ocelli slightly nearer each other than to eyes; face below ocelli somewhat shining, punctures rather fine but deep and distinct, well separated but not sparse, becoming finer and more sparse below, rather close on supraclypeal area, rather coarse but shallow and quite sparse on clypeus, very fine and quite sparse on vertex between eyes and ocelli, margin back of ocelli obscurely roughened; cheeks finely striate posteriorly, rather smooth and subimpunctate along margins of eyes, smooth, shining and impunctate below; wings hyaline, with the usual three submarginal cells, veins pale testaceous, stigma somewhat more brownish; tegulae testaceous-hyaline; legs piceous, but the tarsi pale testaceous; scutum and scutellum shining, obscurely metallic, punctures fine, well separated over most of scutum, becoming rather close and more obscure anteriorly, those on scutellum very sparse; scuturn with a faint, median, sulcus anteriorly; pleura rather densely reticulate or coarsely rugose, hypoepimeral area densely rugose; dorsal area of propodeum rather coarsely reticulate or substriate, lateral faces irregularly striate below, becoming very finely so above, posterior face transversely and irregularly striate; abdominal terga smooth and shining, basal tergum entirely impunctate, 2nd and 3rd with a few exceedingly minute punctures scattered across base, but becoming practically impunctate toward apical margin, the quite broad, impressed, apical areas polished and impunctate.

MALE-Length 4 mm.; entirely black; head slightly broader than long; eyes somewhat convergent below; clypeus rather narrow, convex, densely pubescent; mandibles dark basally, becoming obscurely reddish-testaceous apically; antennae dark, apical segments of flagellum somewhat more piceous, basal segment considerably broader than long, subequal to pedicel in length, 2nd and following segments slightly longer, but hardly as long as broad; lateral ocelli subequally distant from each other and eyes; face below ocelli rather dull, punctures very fine but deep and distinct, uniformly close, those below antennae obscured by dense, white tomentum; vertex between eyes and ocelli more shining, punctures minute and indistinct, margin back of ocelli obscurely roughened, cheeks obscurely and narrowly striate posteriorly, becoming somewhat smoother along margins of eyes, smooth and shining below; wings hyaline, with the usual three submarginal cells, veins pale testaceous, stigma somewhat more brownish; tegulae brownishhyaline; legs dark, but apical tarsal segments more testaceous; scutum and scutellum quite smooth but rather dull, sparsely punctate, punctures on scutellum somewhat finer than on scutum; pleura, including hyoepimeral area, quite densely but finely rugose; dorsal area of propodeum rather coarsely but irregularly striate, lateral faces rather smooth above, with a few obscure striae below, posterior face obscurely roughened; abdominal terga smooth and shining, obscurely metallic, basal tergum with a few obscure, very minute punctures scattered across middle, 2nd and 3rd with minute, rather evenly distributed punctures across basal half of discs, becoming nearly impunctate toward the narrow, impl-ssed, apical margins which are entirely impunctate; gonostyli (fig. 113) very short and rather robust, not exceeding penis valves, with a hatchet-shaped, more or less excavated lobe beneath.

DISTRIBUTION-Minnesota and Ontario to the New England states, south to Texas and Florida; May to September, earlier (March and April) in Florida.

FLOWER RECORDS-Batodendron, Ceanothus, Celeri, Crataegus, Erigeron, Fagopyrum, Houstonia,

Identification
Female Holotype seen by Droege. Has a minute supapical tooth, easy to miss. Hind tibia with clear setae along the dorsal edge, about 5 and slightly curved, the tallest about three-quarters the height of the plumose hairs. Hairs on inner part of tibia short and flattened to surface. A very fine carina lines the edge of the gena, easy to miss. Pits above antennae widely separated and integument very shiny. Mesepisturnal mound below the attachment of the frong wing highly rugose.
