This work reviews present knowledge of the morphology and biology of bees in general, but emphasizes northwestern forms and, in many instances, uses them as standards of reference. No attempt is made to systematically cover morphological and biological information for each taxon, although morphological information of particular value for the separation of taxonomic groups is included.
