In a report published in 1970, 190 species of wasps were reported from Jackson Hole, Wyoming, and notes were presented on the biology of several ground nesting species. In this paper, records of 18 additional species are presented. A short account of the biology of a ground nesting species, Tachysphex aethiops Cresson, is included. Also included are accounts of four species that accepted wooden trap nests during the summer of 1971: Symmorphus cristatus (Saussure), Ancistrocerus adiabatus (Saussure), both Eumenidae; Trypoxylon aldrichi Sandhouse, Passaloecus cuspidatus Smith, both Sphecidae. Notes are presented on nest structure, prey, and parasites in each instance.
