FEMALE—Length 6 mm.; black; length of face subequal to distance between eyes above; eyes subparallel; cheeks slightly broader than eyes; process of labrum large, nearly as long as the basal width, broadly rounded apically; facial foveae very shallow and obscure, narrow and elongate, terminated below about at level of antennae; space between margin of vertex and lateral ocelli only very slightly exceeding their diameter; median segments of flagellum very slightly longer than broad; surface of head smooth and shining, punctures deep and distinct, but rather sparse in general, somewhat closer between antennae and ocelli, becoming more widely separated on vertex laterally, minute and very sparse on cheeks, coarse and sparse on clypeus, supraclypeal area and lateral areas of face below antennae; pubescence of head and thorax short, entirely pale, rather copious, but not at all hiding surface; tubercles black, tegulae brownish-hyaline; wings subhyaline, the veins testaceous, stigma more brownish; 2nd recurrent vein entering 2nd submarginal cell very near the apex; legs dark, except for the yellowish, apical, tarsal segments; spurs yellow; scutum shining, punctures rather deep, well separated, somewhat closer along anterior margin but quite sparse toward center posteriorly, those on scutellum quite sparse, the surface polished; pleura rather dull, punctures fine and well separated, but hardly sparse; apical margins of abdominal terga rather broadly and evenly depressed, these areas microscopically pebbled, disc of basal segment polished and very sparsely and minutely punctate, 2nd segment shining, more distinctly but still rather sparsely punctate, terga 3 and 4 somewhat less shining, but very minutely and quite sparsely punctate, discal pubescence short, very thin and obscure, entirely pale, forming a rather dense, apical, brownish fimbria on tergum 5.

MALE—Length 6 mm.; black; face very slightly longer than distance between eyes above; eyes subparallel; cheeks subequal to eyes in width; lower half of clypeus yellowish, the upper and lateral margins broadly blackish; labrum, mandibles and all other areas of head black; process of labrum large, nearly as long as the basal width, broadly rounded apically; facial foveae very shallow and obscure, hardly visible, narrow and elongate, space between margin of vertex and lateral ocelli subequal to their diameter; median segments of flagellum considerably longer than broad; face between antennae and ocelli rather dull, punctures fine, rather shallow, well separated, becoming somewhat more deep and distinct, rather close on vertex laterally, but very minute and obscure on the shining cheeks; face below antennae shining, punctures quite sparse and fine, especially on lower portion of clypeus; pubescence of head and thorax short, entirely pale, rather copious, but not at all hiding surface; tubercles black; tegulae brownish-hyaline; wings subhyaline, veins testaceous to brownish, stigma more brownish; 2nd recurrent vein entering 2nd submarginal cell very near apex; front and mid tarsi and spurs yellow, the hind tarsi yellow anteriorly, the hind border dark, front tibiae yellow anteriorly, otherwise dark, the mid and hind tibiae entirely dark except for a small yellow basal spot; dorsum of thorax shining, punctures fine, distinct and quite widely separated except along the narrow anterior margin of scutum, those on pleura very fine, and rather sparse; apical margins of abdominal terga rather narrowly but deeply depressed, somewhat shining, discs of the terga somewhat shining, very closely and microscopically punctate, with deeper and more distinct, sparse and fine punctures superimposed upon this field, discal pubescence very short, thin and obscure, entirely pale; sternum 6 strongly narrowed apically, the lateral apical angles somewhat prolonged and subacute; sternum 7 with a quite broadly truncate apical margin, bearing a pair of elongate, compressed processes in the center; apical process of sternum 8 abruptly and strongly dilated at apex, this process broadly truncate, basal two-thirds of the process rather broadly expanded laterally; gonostyli quite small in comparison with the gonocoxites, slender at base, the apical two- thirds slightly expanded, narrowly rounded apically; penis valves somewhat more robust, slightly flexed toward base, otherwise slender and parallel-sided with a quite dense inferior fringe of setae toward the apex.

DISTRIBUTION — Maryland to Mississippi; April to June.

FLOWER RECORDS — Collected at Raleigh, N. C., in April, on Polycodium.
