A very rare complete set of original offprints (each individually page-numbered) in which massive numbers of new species and genera from the South American lepidopterological fauna are described. Individual issues contain between 7 and 101 pages, and were issued irregularly. The author, the French entomologist Paul Dognin (1871-1931) collected over 82,000 specimens, which are now in the Smithsonian Institution in Washington, DC. The publisher, Oberthur, was a lepidopterologist too. Provenance: with on the front pastedown a pictorial, lepidopterological bookplate of the French medical biologist and entomologist Paul Thiaucourt (1928-2022), whose lepidopterological collection is now in the Muséum National d'Histoire Naturelle in Paris. Spine bands and edges a trifle worn; otherwise a very good, clean copy. Cat. BM(NH) Suppl., p. 274.
