Genus PSEUDEPIPONA Subgenus PSEUDEPIPONA Saussure 



Pseudepipona Saussure, 1856. Etudes sur la famille des Vespides, v. 3, p. 309. Proposed 

 originally as a division of Odynerus subg. Epipona Shuckard; validated by Op. 893, 

 Internatl. Comn. Zool. Nomencl., 1970. 



Type-species: Odynerus herrichii Saussure. Monotypic 



Only the typical subgenus occurs in North America. The Palaearctic /(. herrichii (Sauss.) nests 

 gregariously, making short burrows in firm sandy soil and preys upon larvae of Microlepidop- 

 tera.

Genus EUODYNERUS Dalla Torre 



Some of our species belong to the subgenera Pareuodynerus and typical Euodynenis. Others 

 belong to one or more apparently undescribed subgenera. So far as known the subgenera 

 Knemodynerus, Syneuodynerus and Xanthodynerus do not occur in the New World. 



Our species have quite diverse nesting habits. A few species make original mud nests on rocks 

 and a few dig burrows in the soil. The majority of species nest in cavities in twigs, stems, struc-
