The majority of species of this genus are found in the warmer parts of Europe, Asia, and 

 Africa. In the United States, members of this genus are found in the southern tier of states 

 from Florida to California. The colonies are small and nests are constructed in soil and in plant 

 cavities. They are easily transported by commerce and aU the species below may have been in- 

 troduced.
