Note 8 — Part I. ON THE SEASONAL DIMORPHISM OF BUTTERFLIES.
Raphael Meldola translation
[A phenomenon somewhat analogous to seasonal change of protecting colour does occur in some Lepidoptera, only the change, instead of occurring in the same individual, is displayed by the successive individuals of the same brood. See Dr. Wallace on Bombyx Cynthia, Trans. Ent. Soc. Vol. v. p. 485. R.M.]
