context_page_description: Papilio ajax Linnaeus, 1758 is a scientific name given in 1758 by Linnaeus to what later appeared to be a combination of three species of butterflies. The name was placed on the Official Index of Rejected and Invalid Specific Names in Zoology in 1954 after an application to that matter was submitted by Steven Corbet in 1945. The name no longer has a status as a scientific name, except in cases of homonymy; according to the rules of the International Code of Zoological Nomenclature the name Papilio ajax can no longer be given to any species.
context_section_description: In the forties of the twentieth century, Steven Corbet was deputy-keeper of the insect collection of the Natural History Museum. He was at that time also the foremost authority on the Linnean butterflies, and had access to the collection of the Linnean Society. During research, Corbet found the specimen labelled Ajax in Linnaeus's own handwriting. From the way it was pinned, Corbet concluded that it was almost certainly a specimen collected by Pehr Osbeck in Canton in 1751, so not of North-American origin. Corbet at once identified the type as a specimen of the Oriental species named Papilio xuthus by Linnaeus in 1767, a name by which it has ever since been known.
