I take this opportunity to state that Bombus medius Cresson, supposed to 
have been collected by Suckley in Utah, is really Me.xican. Prof. C. H T. 
Townsend took it abundantly near San Rafael, on the Rio Nautla, State of Yera 
Cruz, March 8 to April 8, on si.x different species of flowers (his numbers 4, 15, 
19, 23, 25 and 28), and I find specimens labelled “Mexico” both in the collection 
at Philadelphia and that at Washington.
