FEMALE—Length 6 mm.; piceous to black; length of face subequal to distance between eyes above; eyes subparallel; cheeks subequal to eyes in width; process of labrum considerably broader than long, slightly narrowed, but the apex very broadly truncate; facial foveae rather small and shallow, terminated slightly above level of antennae; space between margin of vertex and lateral ocelli considerably less than distance between them; median segments of flagellum slightly longer than broad; punctures of face above antennae fine and very close, somewhat coarser and more sparse below antennae, quite coarse on clypeus, somewhat coarser but still close on vertex laterally, and close on cheeks except beneath; pubescence of head and thorax short, entirely pale, rather dense above but not hiding surface; tubercles dark; tegulae pale yellowish-hyaline; wings subhyaline, veins and stigma testaceous, 2nd recurrent vein entering 2nd submarginal cell much nearer apex than 1st does to base; spurs and hind tarsi yellow, legs otherwise dark except for small basal yellow spots on front and mid tibiae; scutum shining, punctures fine and well separated but not sparse, those on scutellum slightly coarser, quite close; pleura shining medially, but closely and rather finely punctate above, below and anteriorly; apical margins of abdominal terga rather shallowly and broadly depressed, these areas reddened, very minutely and quite closely and obscurely punctate or reticulate, discs of the terga shining, minutely punctate, the first tergum sparsely so, the others more closely so except apically toward the depressed rims, discal pubescence short, thin and obscure but evident, entirely pale, forming a pale brownish, apical fimbria on tergum 5.

MALE—Length 5 mm.; piceous to black; face considerably longer than distance between eyes above; eyes slightly convergent below; entire clypeus, except for narrow apical borders laterally, labrum, mandibles, a quadrangular spot on supraclypeal area and triangular lateral maculae, yellow, maculae ending acutely on eye margin at about level of antennae; cheeks slightly narrower than eyes; process of labrum broader than long, lateral margins obscure, apparently somewhat narrowed apically to the truncate apex; facial foveae extremely small but distinct, located considerably above level of antennae; space between margin of vertex and lateral ocelli only very slightly greater than their diameter; median segments of flagellum slightly longer than broad; punctures of face above antennae fine and close, rather shallow, those below antennae deep, distinct and more widely separated, becoming quite coarse on clypeus where they are almost sparse, close on vertex laterally, becoming slightly more sparse on cheeks below; pubescence of head and thorax short, thin, entirely pale, rather copious above but not hiding surface; tubercles slightly reddened; tegulae yellowish-hyaline; wings subhyaline, veins yellowish, stigma somewhat more testaceous, 2nd recurrent vein entering 2nd submarginal cell only very slightly nearer apex than 1st does to base; tarsi and spurs yellow, the femora dark except for small, apical, yellow spots, front tibiae yellow anteriorly, dark posteriorly, the mid and hind tibiae dark medially with yellow base and apex; punctures of dorsum of thorax quite deep and distinct, rather fine, close along narrow anterior margin of scutum, becoming somewhat more widely separated posteriorly, somewhat more coarse and sparse on scutellum laterally, but close along mid line, sparse, shallow and rather coarse on pleura medially, becoming somewhat closer above and below; apical margins of abdominal terga rather narrowly and deeply depressed, these areas quite smooth, shining, somewhat reddened, discs shining, quite deeply and finely punctate, punctures on tergum 1 rather sparse medially and toward the apical depressed rim, punctures of terga 2 and 3 closer, becoming finely rugose along basal margins, somewhat sparse toward apical rims, discal pubescence very short, thin, sparse, entirely pale; sternum 5 with a narrow and rather obscure, median, apical emargination; wings of sternum 7 rather broad, subacute apically, and bearing a few abruptly recurved apical bristles; apical portion of sternum 8 rather broad, sides nearly parallel, slightly flexed apically and bearing a double tuft of very short apical setae; gonostyli rather short and robust, slightly curved, tip abruptly flexed and very slender, bearing a quite dense, subapical tuft of quite long setae; penis valves slightly shorter than gonostyli, rather slender and simple.

DISTRIBUTION—Illinois, east to the New England states and south to Mississippi, during the fall.

FLOWER RECORDS—Robertson (1929) records this on Bidens aristosa, Boltonia asteroides, Coreopsis tripteris, Helianthus grosse-serratus, H. tuberosus, Rudbeckia subtomentosa and Solidago canadensis.
