vii + 580 pp. and 4 colour plates. Provides keys to all the genera and species of New World Polistinae. Keys are poorly illustrated and in many cases only useful for experts. Key to Polistes difficult to use because it also includes the numerous Central and South American species. Separation of females of the widespread, hypervariable P. fuscatus from related species often inaccurate. Key to Polistes males does not work for most species.
