FEMALE—Length 5 mm.; black to piceous; face slightly longer than distance between eyes above; eyes sub-parallel; cheeks sub- equal to eyes in width; process of labrum quadrangular, about as long as broad, apex truncate; facial foveae rather shallow but distinct, terminating slightly above level of antennae; space between margin of vertex and lateral ocelli subequal to distance between them; median segments of flagellum slightly longer than broad; punctures of head fine and shallow, very close above antennae and on supraclypeal area, somewhat coarser and more distinct on lateral portions of face below antennae and much more coarse on clypeus, very minute, close and indistinct on vertex laterally, becoming somewhat coarser and more distinct but quite shallow on cheeks below; pubescence of head and thorax very short, thin and obscure, barely evident on dorsum of thorax, but pronotum with a rather dense posterior fringe of short, scale-like pubescence; tubercles dark; tegulae yellowishhyaline; wings subhyaline, veins pale testaceous, stigma somewhat darker, 2nd recurrent vein entering 2nd submarginal cell very close to apex, the 1st widely removed from base; front and mid tibiae with a small, yellow, basal spot, legs otherwise dark; spurs yellow; puncturation of dorsum of thorax uniformly fine and close, that on pleura obscure over posterior portion, this being more tessellate but with some shallow and somewhat coarser punctures over anterior portion; apical margins of abdominal terga rather broadly and shallowly depressed, these areas very closely and minutely punctate, somewhat reddened, discs very finely and rather evenly punctate, the punctures quite close toward base, more sparse toward apex of each tergum, discal pubescence very short, thin and obscure, entirely pale, forming a quite dense, brownish, apical fimbria on tergum 5.
MALE—Length 5 mm.; black; length of face slightly greater than distance between eyes above; lower end of eyes strongly divergent, clypeus much broader than long; clypeus, except for the narrow apical margins laterally, labrum, mandibles and small lateral maculae, yellow, the maculae not extending above upper margin of clypeus; cheeks broader than eyes; process of labrum subtriangular, slightly broader than long; facial foveae quite broad, deep and distinct, terminating slightly above level of antennae; vertex broad, lateral ocelli much nearer each other than to margin of vertex; median segments of flagellum much longer than broad; punctures of head fine but quite deep and distinct, close between antennae and ocelli, more widely separated but not sparse below antennae, considerably coarser on clypeus, more distinct and widely separated between eyes and ocelli, becoming shallow and obscure on vertex laterally and upper portion of cheeks, lower portion of cheeks shining and very obscurely punctate; pubescence of head and thorax very short, thin and obscure, entirely pale, hardly visible except at certain angles on dorsum of thorax; tubercles yellowish; tegulae yellowish-hyaline; wings subhyaline, veins testaceous to brownish, stigma rather dark brown, 2nd recurrent vein entering 2nd submarginal cell very close to apex, the 1st rather widely removed from base; tarsi and spurs yellow; femora dark except for yellow tips, front tibiae yellow anteriorly over basal two-thirds, dark posteriorly, mid and hind tibiae largely dark with yellow base and apex; punctures of dorsum of thorax uniformly very fine and close, pleura more tessellate, but somewhat shining over anterior portion, with shallow and rather coarse, well separated punctures; apical margins of abdominal terga rather broadly and shallowly depressed, these areas very minutely and closely punctate, somewhat reddened, discs of terga very finely but quite distinctly punctate, the punctures close toward base, more sparse toward depressed margin of each tergum, discal pubescence extremely short, thin and obscure, entirely pale; sternum 6 with a deep, triangular, median emargination; wings of sternum 7 quite broad, semicircular, tips very slightly reflexed, bearing a small tuft of short setae; apical process of sternum 8 rather strongly flexed ventrally, quite narrow, tip bearing a tuft of short setae; gonostyli slightly flexed toward median line apically, apex acute, apical half bearing a strong and conspicuous fringe of long curved setae; penis valves simple, slender, not quite attaining tips of gonostyli.
DISTRIBUTION—Georgia to Maryland and West Virginia; May and June.
