In the Plusiine species, Argyrogramma albostriata (Bremer et Grey), the distinct two forms of the wing-pattern are observed, i.e., a marked wedge-shape stigma is present on the fore wing in ordinary form named f. albostriata (A-form), while it is absent in another, less abundant one, named f. innotata (I-form). By inbreeding experiments of the successive generations of the two forms, following new informations on the subject were obtained : 1) It is under the genetical control whether the wing-pattern will exhibits A-form or I-form. 2) The strains derived from the wild A-form females produced consistently only A-form in both the first and second filial generations. 3) The adults of the first generation produced by the I-form wild female had A-form wing-pattern exclusively, but those of the 2nd filial generation segregated into two forms, A and I, at the ratio of about 3 : 1 without distinction of sex. 4) The phenotypes of individuals produced by the homomorphic parents of I-form were all of I-form without exception. 5) It follows from these results, that the complete dominance in Mendel's laws of heredity holds good for this phenomenon, and that the two forms, A and I, in the wing-pattern of Argyrogramma albostriata are of allelomorphic characters, i. e. the former is dominant, the latter being recessive. 6) Three females of aberration having a particular form of wing-pattern different from either of the preceding two forms were obtained in 1964, among ordinary A-form adults developed in another rearing stock which is derived from some other wild A-form females. This aberrant form possibly corresponds to Strand's ab. acuminata. 7) The phenotypes of the hybrid produced by the female aberration, acuminata crossed with the homozygous or heterozygous A-form male were also all of A-form. It remains unexplained, however, what kind of factors are concerned in the appearance of this aberrant form.
