The Pentatomini in the Quarto catálogo dos insetos que vivem nas plantas do Brasil are brought up to date. Vouching specimens in several collections on which Catalogue entries have been based, were reidentified by us. The nomenclature of the species is revised under the provisions of the International Rules. All bibliographic references have been checked and a short comment on their contents is given. A recomendation is strongly made in order that further publications on phytophagous insects be substantiated by mention of vouching specimens, to be preserved in entomological collections, avoiding encumbering agricultural literature with unverifiable data.
