Calosoma semilaeve LeConte, 1852

Calosoma semilaeve LeConte, 1852a: 199. Type locality: "San Jose; San Diego [California]" (original citation), restricted to "San Diego [San Diego County]" by Gidaspow (1959: 271). Syntype(s) in MCZ [# 628].

Calosoma semilaevis davidsoni Casey, 1914: 33. Type locality: "Alameda Co[unty], California" (original citation). Two syntypes in USNM [# 37116]. Synonymy estab lished by Breuning (1928a: 111). Etymology. The subspecific name was proposed for George Davidson [1825-1911], surveyor, geodesist, and astronomer. Born in England, Davidson was put in charge of the survey on the west coast in 1850 soon after the United States took over California from Mexico. The Davidson Seamount off the coast of California and Mount Davidson and Davidson Street in San Francisco are named for him.

Calosoma semilaevis adjutor Casey, 1920: 162. Type locality: "Alameda [Alameda County], California" (original citation). One syntype in USNM [# 37115]. Synonymy established by Breuning (1928a: 111).

Distribution.

This species ranges from eastern Oregon and “Idaho” (Gidaspow 1959: 271) south to southern Arizona (Snow 1907: 141) and southern California along the coast (Fall 1901a: 40; Moore 1937: 4); also found on Guadalupe Island, Mexico (Gidaspow 1959: 271). The record from northeastern Kansas (Popenoe 1877: 22) is likely in error.
