Tribe CENTRIDINI 



This is a New World group of pollen-collecting bees which are especially abundant in the trop- 

 ics although some species are present in the warm temparate regions of both continents. The 

 tribe contains two genera, Centris and Epicharis, but only the genus Centris occurs in America 

 north of Mexico.
