This is a dominant cosmopolitan g-enus, of which nearly ninety species 

 occur in North America. In Europe only TWO species have been found 

 fossil, in Pleistocene deposits of France and Galicia, and both are regarded 

 as recent species. In America, six species, all extinct, have been found in 

 the Pleistocene of Canada, while three others occur in the older Tertiary 

 deposits of Wyoming and Colorado.
