Nye (1975) stated:-
Invalid type-species designation by Boisduval, 1836, Hist. nat. Insectes (Lepid.) 1: 144, who also cited xanthographa. Boisduval in his lengthy 154 page Introduction reviewed earlier classifications and designated up to three different type-species for each generic name. In his 'Expose de notre methode from pages 155-690, no type-species designations were made for the genera he himself used. Under the Code, Article 69 (a) (iii), the type-designation of an author is eligible for consideration if he stated that it is the type'. . . and if it is clear that he himself accepts it as the type-species.' Boisduval's type-designations, although clearly stated, do not fulfil the last requirement and so are invalid. Even though Boisduval's 1836 work was well know to lepidopterists, the type-designations contained in it have not in the past been accepted by Hemming for Rhopalocera, or by other authors.
