Centuria Insectorum (Latin, "one hundred insects") is a 1763 taxonomic work by Carl Linnaeus, and defended as a thesis by Boas Johansson; which of the two men should for taxonomic purposes be credited with its authorship has been the subject of some controversy. It includes descriptions of 102 new insect and crustacean species that had been sent to Linnaeus from British America, Suriname, Java and other locations. Most of the new names included in Centuria Insectorum are still in use, although a few have been sunk into synonymy, and one was the result of a hoax: a common brimstone butterfly with spots painted on was described as the new "species" Papilio ecclipsis.
