JEgeria has been divided by Hiibner and Newman into several 
genera, which differ as much from each other as they do from 
Sphecia , but they are here reunited, for the characters by which 
they are distinguished will not apply to the exotic species, and the 
latter, as yet, can hardly be divided into corresponding genera.
