Fletcher (1979) stated:-
A junior objective synonym of Hydriomena Hübner, . Invalid designation of type-species: Geometra elutata Hübner, , was designated by Boisduval, 1836, Hist. nat. Insectes. (Spec. gén. Lépid.) 1: 147.
In the Introduction to the volume, pages 1-154, Boisduval reviewed earlier classifications of Lepidoptera and designated as many as four different type-species for each genera name. In his `Exposé de notre méthode', pages 155-690, no type-species designation was made for any of the genera that he himself used.
Under Article 69(a)(iii) of the Code, 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 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 known to lepidopterists, the type-species designation contained in it have not been accepted, either by Hemming or by other authors. The acceptance of Boisduval's type-species designation in this case would make no difference to the generic concept.
