This species, based on a unique specimen, is very similar to A. gardineri Cockerell. The following brief description, stressing chiefly the difference in comparison with gardineri, was made from the type specimen (No 17076) in the collection of the Illinois Natural History Survey:
FEMALE. — Process of labrum truncate and just perceptibly emarginate; clypeal punctures quite sparse near mid line; basal segment of flagellum no more than equal to segments 2 and 3 combined; punctures of scutum and scutellum somewhat more sparse and fine than in gardineri; pleura and propodeum as in gardineri; basal abdominal tergum quite finely and sparsely punctate except toward apical margin which is narrowly yellowish-hyaline; punctures of following terga deep, distinct and rather coarse, interspaces averaging about twice diameter of punctures; tegulae brownish-testaceous; wings hyaline, violaceous, veins and stigma pale yellow, 1st recurrent vein reaching 2nd submarginal cell nearly at apex; pubescence entirely pale ochraceous; abdominal terga 2-4 with rather narrow and dense, yellowish, apical fasciae, that on segment 2 interrupted medially.
DISTRIBUTION. — Illinois.
FLOWER RECORDS. — Recorded by Robertson (1929) on Sassafras varifolium.
