FEMALE—Length 7 mm.; head and thorax greenish, abdomen piceous, the maculae lemon yellow; length of face somewhat greater than distance between eyes above; eyes slightly convergent below; cheeks subequal to eyes in width; vertex quite broad, lateral ocelli slightly nearer its posterior margin than to eyes; foveae rather elongate, somewhat narrowed below, quite deep and distinct; mandibles robust, the apical third abruptly flexed, yellowish, becoming reddish apically; labrum dark; clypeus rather strongly protuberant, considerably broader than long, yellow, with a pair of triangular dark areas above which meet at midline, and apical margin darkened; facial maculae filling area between clypeus and eye, truncate above, not extending above upper margin of clypeus; scape yellow anteriorly, flagellum piceous above, testaceous beneath; lower portion of face shining, more brassy green except for the maculae, punctures very fine, rather close and quite distinct, upper part more olive green, dull and tessellate, punctures exceedingly minute and obscure, cheeks somewhat shining but very closely and minutely punctate; pubescence of head and thorax short but rather dense, pale fulvous above, becoming whitish below; posterior margin of pronotum and tubercles yellow, thorax otherwise brassy green; tegulae yellowish-hyaline; wings milky- white, veins and stigma pale yellowish or nearly colorless; legs brown except for small, basal, yellow spots on front and mid tibiae; scutum and scutellum shining between very fine, close, deep and distinct punctures, the pleura somewhat darker green, not so shining, punctures more minute and obscure, propodeum somewhat bluish; discs of abdominal terga 2-5 with transverse, yellow, basal bands, those on 2 and 3 slightly interrupted medially, basal tergum with a pair of very small lateral spots; integument of basal tergum rather dull, without distinct punctures, the more apical segments somewhat more shining, with fine, sparse, obscure punctures toward the slightly depressed apical rims.

MALE—Length 7 mm.; head and thorax greenish, abdomen piceous; face slightly shorter than distance between eyes above; eyes very slightly convergent below; cheeks much broader than eyes, with rounded angles opposite upper and lower ends of eye; vertex broad, lateral ocelli only very slightly nearer its hind margin than to eyes; foveae very short, shallow and obscure, hardly evident; mandibles slender and elongate, the tip of one reaching base of the other when closed, yellow, with fuscous slender tip; labrum yellowish, somewhat swollen; clypeus not strongly produced, rather small, greenish, with lateroapical yellow maculae; lower margin of face between clypeus and eye narrowly yellow; scape yellow anteriorly, flagellum piceous above, testaceous beneath; face below antennae shining, more brassy green, with fine, sparse, distinct punctures, cheeks and face above more olive green, dull and tessellate, face with hardly evident punctures, cheeks with very minute, indistinct and rather sparse punctures; pubescence of head and thorax rather dense, yellowish, becoming whitish on thorax below; thorax brassy green, without maculae; tegulae yellowish-hyaline; wings milky-white, veins and stigma pale yellow or nearly colorless; legs largely dark, front and mid tibiae with a small, basal, yellow spot; scutum and scutellum shining, with fine and rather sparse, distinct punctures, pleura less shining, punctures minute and sparse; basal abdominal terga dull, with hardly evident punctures, the more apical terga becoming somewhat more distinctly punctate, terga 2 and 3 with small, lateral, yellow marks; sternum 7 with a broad and deep, quadrangular, median emargination; apical process of sternum 8 rather narrow and elongate, the tip compressed and acute, bearing a tuft of short hairs, the basal part parallel-sided; gonostyli of moderate length, broadly and strongly compressed, the tips acute, penis valves slightly exceeding gonostyli, parallel-sided and rather robust, volsellae compressed, with a slender, distinct digitus, gonocoxites produced apically into a pair of slender, acute lobes.

DISTRIBUTION—Kansas and Nebraska to Wisconsin and Indiana; June to September.


The typical form of albipennis (Cresson, i868. Amer. Ent. Soc. Trans. 1, p. 386) is western in distribution, and according to Timberlake does not occur east of Kansas and Nebraska. Females differ from the eastern pallidipennis in the small size of the lateral facial maculations, which may be entirely lacking. In the male also the face is much darker, lacking the lateral maculae, and the clypeus nearly or entirely dark.
