Identification
Extracted from: Sandhouse G. A. New North American Species of Bees Belonging to the Genus Halictus (Chloralictus). No. 2532 - Proceedings U.S. National Museum. Vol. 65, Art. 19.

Female.�About 5.5-6 mm. long; golden or brassy green; pubescence yellowish white. Facial quadrangle about as long as broad; front and vertex very closely punctured, the punctures becoming more scattered on the sides of the face; supraclypeal area and upper half of clypeus shining golden green with a few coarse punctures; lower half of clypeus black; inner orbits converging below; antennae dark,the flagellumrufo-testaceousbeneath. Meso thorax microscopically lineolate, very closely punctured; scutellum with deep punctures, two small polished spots on the disk; disk of propodeum coarsely granular with rather faint irregular rugae making a reticulate surface, without an inclosing rim, but polished apically; mesopleura irregularly punctured; truncation well defined laterally; tegulae very pale testaceous, impunctate. Abdomen obovate, impunctate; the segments clothed with dense pubescence; apical margins of segments pale testaceous. Wings faintly yellowish; anterior wing 4.5 mm. long; stigma and nervures pale testaceous ; second submarginal cell almost as broad as long, and almost as long as the third on the marginal; third submarginal gently contracted above, first recurrent nervure joining the second transversocubital; subcosta very dark. Legs dark with yellowish pubescence.

Differs: From vegans Cockerell in having a broader head; paler tegulae and wings; head and thorax green; sculpturing of disk of propodeum distinct.

From jloridanus Robertson by the broader head; clypeus and supraclypeal area distinctly brassy; paler hairs; head and thorax golden green; disk of propodeum not granular.

From succinipennis Ellis by the broader head; more closely punctured head and thorax; shorter disk of propodeum with distinct sculpturing.
