M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico. Chrysis provancheri Schulz Chrysis aurichalcea Provancher 1881:300. Lectotype female, Canada (Quebec). Chrysis provancheri Schulz 1906:154. New name for aurichalcea Provancher. Nec aurichalcea Lepeletier 1806. Discussion: The green to blue or purple thorax and coppery red abdomen is reminiscent of the common color pattern in the Palearctic Region. However, a comparison with the many European species available has not turned up a match. The only other American Chrysis with similar markings are pompella and charigaster, the latter in a different group. Features of provancheri other than color are the rather short and dull teeth of T-III, the lateral ones weak; pit row not deeply impressed, scutellum closely punctate, and wings brown stained. Male genitalia are similar to those of scitula but S-VIII of provancheri is more triangular, the posterior part tapering to a point rather than broadly rounded. Material examined: 12 males, 24 females (including type of aurichalcea). Distribution: northern U.S. from the DAKOTAS to MAINE, and the southern tier of Canadian Provinces from British Columbia to Nova Scotia; also in NORTHWEST TERRITORIES (Norman Wells), YUKON TERRITORY (McQuesten), and ALASKA (Fairbanks). Species group of dorsalis Aaron Diagnosis: Male F-I longer than F-III and about 1.5-2.0 times as long as broad, female F-I 2.0-2.5 times; subantennal distance a little more or less than 1.0 MOD, shorter than malar space which is 1.5- 2.0 MOD, transverse frontal carina absent or rarely indicated (montana female); in which case eye height equals LID; genal carina separated from eye; midocellus not depressed or lidded; mesopleuron and metanotum rather simple; T-II with a weak and ill-defined median longitudinal ridge; T-III distally with a simple edge and four teeth, laterally a little irregular but essentially straight. Included species: allectoris Bohart, dorsalis Aaron, equidens Viereck, knowltoni Bohart, Aaron, montana Aaron, paradisica Bohart, pompella Bohart, provancheri Schulz, and scitula Cresson. Discussion: External characters for species separation are meager in some cases. However, male genitalia, particularly the parameres, are usually definitive (figs. 230-239). Two essential characteristics of these relatively small species are the absence of a definite frontal carina and a moderately long male F-I. The coppery to red coloration in three of the species is unusual among American Chrysis. Hosts: probably ground nesting bees or wasps (see comments under dorsalis).
