Andrena rufosignata Cockerell, 1902: 46 [♀].

     Holotype ♀. USA, Wisconsin, Milwaukee, 19 May [year not provided], by S. Graenicher, on Ulvularia grandiflora [USNM no. 18923].

*Andrena Harveyi Viereck, in Viereck et al. 1904: 192, 194, 224 [♀, ♂]. Synonymy by LaBerge (1980: 462).

     Holotype ♀. CANADA, British Columbia, Vancouver, Grouse Mt., 19 July 1903, by Harvey [ANSP no. 4089].

Andrena salicicola Viereck and Cockerell 1914: 52 [♀]. Synonymy by LaBerge (1980: 462).

     Holotype ♀. USA, Colorado, Pikes Peak, Halfway House, 30 May 1904, by T.D.A. Cockerell, on Salix [USNM no. 18161].

Andrena (Andrena) media Viereck 1922: 41 [♂]. Preoccupied, not Andrena media (Radoszkowski, 1891). Synonymy presumed to be by LaBerge (1980: 462).

     Holotype ♂. USA, New Hampshire, Glen House, Green Grant, 14 June 1916, by C.W. Johnson [MCZ no. 29827].


Taxonomic notes: Mitchell (1960: 229), and subsequently Hurd (1979: 1787) included A. media Viereck as a synonym under A. durangoensis Viereck and Cockerell, 1914. As LaBerge (1980: 464) was not able to locate the type material, it is not known what his placing this species into synonymy under A. rufosignata was based on, though it is included here as it is the most thorough and recent taxonomic treatment of the group. However, the type is at the MCZ, where they have it classified as A. durangoensis.
