Fletcher & Nye (1982) stated:-
Invalid designation of type-species: Phalaena lanestris Linnaeus, 1758, was also designated by Boisduval, 1836, Hist. nat. Insectes (Spec. gén. Lépid.) 1: 129, 143.
In the Introduction to the volume, pages 1-154, Boisduval reviewed earlier classifications of Lepidoptera and designated up to three different type-species for each generic name. In his `Exposé de notre méthode`, pages 155-690, no type-species designation was made for any of the generic names that he himself used. Under the Code, Article 69(a)(iii), the type-designation of an author is eligible for consideration if he states that it is the type `... and if it is clear that he himself accepts it as type-species'. Boisduval's type-dsignations, although clearly stated, do not fulfil the last requirement and so are invalid. Even though Boisduval's 1836 work was well known to lepidopterists, the type-species designation contained in it to lepidopterists, the type-species designations contained in it have not been accepted, either by Hemming or by other authors.
