FEMALE— Length 10-11 mm.; face somewhat longer than its greatest breadth; eyes convergent below; length of malar space about one-fourth its breadth; facial foveae narrow but rather deep, obscured by a covering of whitish tomentum; antennal segments fully as broad as long; clypeus very slightly produced below suborbital line, shining, rather closely and irregularly punctate, punctures finer and closer laterally and above; supraclypeal area bare, more finely punctured, punctures well separated medially; face otherwise densely covered with whitish, feathery pubescence, obscuring the surface; vertex bare and shining, with a few scattered very fine punctures; cheeks densely pubescent above, bare and closely, finely punctate below; antennae dull ferruginous beneath; pubescence entirely white, with a slight creamy tint on dorsum of thorax; lateral faces of prothorax unusually extensive, bare, anterior margin carinate. angles not spined ; metapleural protuberance conspicuously carinate, margin of the carina testaceous; tegulae dull ferruginous, wings whitish, violaceous apically, veins and stigma testaceous; scutum largely covered with short, subappressed, feathery pubescence, obscuring the surface, this partially exposed in center posteriorly where the surface is shining and punctures coarse, deep and sparse; scutellum bare anteriorly, shining, with sparse scattered punctures, densely tomentose over posterior portion pleura more thinly pubescent, but pubescence short and feathery, surface closely and quite coarsely and deeply punctate ; lateral faces of propodeum rather densely covered w1th finer pubescence, surface partially- exposed. relatively smooth, dorsal face rather closely striate, resulting shining pits narrow, largely hidden by pubescence; legs, including tarsi, dark, anterior spines well developed; hind basitarsi about three times longer than broad; spurs yellowish-ferruginous ; abdominal terga very finely and closely punctate, punctures on basal segment more distinctly separated, but not sparse; apical margins of terra lightly depressed, conspicuously testaceous beneath the dense, entire, broad, white fasciae; basal half of discs of 2nd and 3rd abdominal terga covered with appressed white tomentum, and basal tergum largely oh— cured by similar pubescence, this becoming somewhat longer and more erect at extreme base.

MALE—Length 8-9 mm.; lace somewhat longer than its greatest breadth; eyes convergent below; length of malar space about one-third its breadth antennae beneath deep ferruginous, length of median segments about one and a half times the breadth; clypeus finely and closely punctate beneath the dense white beard; all of face below antennae covered with long white pubescence, surface above antennae more exposed, with rather close, coarse, distinct punctures; vertex bare and shining, with very fine and rather close punctures; cheeks shining, minutely punctate beneath the dense pubescence; pubescence entirely white, with a slight creamy tint on dorsum of thorax; lateral faces of prothorax unusually extensive, bare, anterior margin carinate, angles not spined ; metapleural protuberance conspicuously carinate, margin of the carina testaceous; legs reddened apically; spurs yellowish; tegulae yellowish-ferruginous; wings whitish, violaceous apically, veins and stigma testaceous; dorsum of thorax covered with long, erect and rather thin, feathery, white pubescence, partially exposing tire surface, punctures of scutum rather coarse and close, but not crowded, closer laterally, quite sparse posteriorly, those on scutellum coarser, sparse anteriorly, crowded along hind margin; pleura quite coarsely and deeply punctate, punctures crowded anteriorly and above, well separated but not sparse below, pubescence long and rather thin; lateral faces of propodeum with long, thin pubescence, surface partially exposed, somewhat shining, dorsal face short. shining between the parallel striae; abdominal terga closely, deeply, distinctly and finely punctate, punctures becoming closer and minute on the more apical segments; apical margins of terga depressed, testaceous-hyaline beneath the dense, entire, white fasciae; discs of 2nd and 3rd abdominal terga with a slight amount of suberect white pubescence across base, otherwise pubescence of abdomen very thin, short, pole and obscure, not obscuring the surface.

DISTRIBUTION—This species is western in its distribution, but ranges into Wisconsin, Illinois and Michigan in the east. It is in flight from mid June to mid August.

FLOWER RECORDS—Stephen records this species on Melilotus, Petalostemun flavescens and P. villosum.
