B. morrisoni is most closely related to B. griseocollis and may be distinguished from it by the characters mentioned in the discussion under that species. This species occurs principally in transmontane California. Three California specimens are not listed in the above records because of the improbŽable validity of the data associated with them. The putative localities include Davis, Yolo Co.; Ahwahnee, Madera Co.; and Yosemite Valley, Mariposa Co. None of these localities have proŽduced additional specimens, and even if the bees were collected where the labels indicate, they may have been accidental introductions without species establishment and therefore of little biogeographical importance.
