Taxonomic Notes on Some American Bumblebees (Hymenoptera: Apidae; Bombinae)

Abstract

Pending completion of the writer's current bumblebee work, the following information should be of interest and use to others who are now devoting attention to the taxonomy of this group in the Western Hemisphere and who contemplate publishing. The existing and recognizable types of all the accepted names referred to beyond were studied except the Gribodo types which were well reviewed by Richards (1929), inrhose homotype of volucelloides was examined at the British Museum (N.H.) in London. The condition and where-abouts of most of the type specimens on which are based the various conclusions presented here, have already been discussed by the writer (1960). There are, however, other types of infraspecific taxa that were not treated at that time, and it is emphasized that a reliable knowledge of these is also important for the present synonymies and other taxonomic considerations.
