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.
