Notes:
Fletcher (1979) stated:-

G. prodromaria is a junior subjective synonym of Phalaena strataria Hufnagel, 1767, Berl. Mag. 4: 514. Invalid designation of type-species: Phalaena betularia Linnaeus, 1758, was designated by Boisduval, 1836, Hist. nat. Insectes (Spec. gén. Lépid.) 1 : 146. 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 generic name. In his `Exposé de notre méthode', pages 155-690, no type-species designation was made for any of the genera 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 fulfill the last requirement and so are invalid.

Even though Boisduval's work was well known to lepidopterists, the type-designations contained in it have not been accepted either by Hemming or by other authors. The acceptance of Boisduval's type-species designation in the case of Biston would make no difference to the generic concept, P. betularia Linnaeus and P. strataria Hufnagel being currently regarded as congeneric.
