Type-species: Sphecodes kathleenae Eickwort. Orig. desig. 



This is a large and nearly worldwide genus of parasitic bees. While most of the species are 

 cleptoparasites in the nests of other Halictinae, some are parasitic in the nests of certain species 

 of Andrenidae and Colletidae. The adults visit a wide variety of flowers often in the company of 

 their pollen collecting hosts. 



There are obviously several subgenera of the genus Sphecodes represented in the Nearctic 

 Region and some of the names cited above are available. However, until further studies are 

 made, it is not possible to estabHsh the limits of the subgenera present in our area.
