Subfamily XYLOCOPINAE 



Although these bees are found throughout much of the world they are especially well 

 represented by numerous species in the tropics. Most of the species are pollen-collecting bees 

 and, unlike most other non-parasitic anthophorids, they usually make their nests in wood of vari- 

 ous sorts. The subfamily contains two tribes, the Ceratinini (small carpenter bees) and the 

 Xylocopini (large carpenter bees) both of which are present in America north of Mexico. 



Tribe CERATININI 



This is a large group of mostly small, almost hairless bees which, except for parasitic species, 

 make their nests in hollow, pithy or rotten stems and sometimes in vines. While there are about 

 a dozen genera of these bees present in the Old World including the cleptoparasitic Eiicon- 

 dylops, Inquilina and Nastdapis, only the nearly worldwide genus Ceratina and the endemic 

 Chilean genus Manuelia are present in the New World. 



Pithitis smaragdula (Fabr.) was intentionally introduced into the United States from Ludhi- 

 ana, India on April 10, 1969 at Davis, California as a potentially important pollinator of economi- 

 cally useful plants, especially legumes and cucurbits (Daly, Bohart and Thorp, 1971. Ent. Soc. 

 Amer., Ann. 64: 1145-1150). The introduction apparently was unsuccessful since no recoveries of 

 this species have been reported.
