Several of the subgenera cited in the above synonymy are doubtless valid, but as the sub- 

 generic groupings of Colletes have not been properly worked out they are listed as synonyms. 



Some species are polytropic, others oligotropic. Several of the principally autumnal species 

 have small vernal broods.
