Notes. According to S. Droege, N. besseyi may be a junior synonym of N. graenicheri ( Cockerell 1905b) , a species known from relatively few specimens from Wisconsin and Ontario ( Wolf & Ascher 2009) and recently reported from Minnesota (S. Droege, pers. comm.). Specimens from Michigan identified as N. besseyi in a revision ( Broemeling & Moalif 1988) closely match images of the N. graenicheri holotype deposited at the NMNH. Broemeling & Moalif (1988) did not treat N. graenicheri in their revision of this group (as subgenus Pachynomada) and it was misplaced in the ruficornis species group by Alexander & Schwarz (1994). Members of this species group are cleptoparasites of Andrena (Callandrena s. l.) ( Broemeling & Moalif 1988)
