Bombus impatiens Cresson, 1863: 90 [♂].

     Syntypes 7♂♂. CANADA, USA - Connecticut, Pennsylvania, Illinois, Missouri [ANSP no. 6322, and E. Norton].

Taxonomic notes: Though the name Bombus impatiens first appeared in a species checklist in the second edition of Hitchcock’s (1835) “Report on the geology, mineralogy, botany, and zoology of Massachusetts”, it was not accompanied by a description; many of Harris’ taxa listed as such have been considered nomen nudum (see Rohwer 1920, for a treatment of Harris’ Symphyta). Rohwer (1920: 509) indicated some of the names used by Harris were manuscript names provided by Thomas Say, and some of these were later examined by E. Norton. 

Though Cresson (1916) designated lectotypes for most of his species originally described with syntypes, Bombus impatiens Cresson, 1863 does not appear in that work.
