Omus audouini Reiche, 1838

Omus audouini Reiche, 1838: 300. Type locality: "versant occidental des montagnes rocheuses, dans le district d’Oregon, aux États-Unis de l’Amérique du Nord" (original citation, see page 297). Syntype(s) probably in MHNP. Etymology. The specific name was proposed for the French zoologist Jean-Victor Audouin [1797-1841], co-founder of the Annales des Sciences Naturelles and a founding member of the Société Entomologique de France. In 1823 Audouin became assistant librarian at the Muséum d’Histoire Naturelle in Paris and obtained his doctorate in 1826. He succeeded Latreille as assistant naturalist at the chair of Crustacean and Insects at the Museum in 1830 and three years later as professor of the same chair. He died of apoplexy. He had no insect collection but held a large entomological library which he willingly made available to scholars.
