• It has been generally accepted that from species to species in the genus Drosophila the wing-indices and wing-lengths vary to the effect that the C-index of the wing (a/b, Fig.1) is negatively correlated with the 4v-index (d/c, Fig.1) (named here "Sturtevant's rule"), and also with 4C-index (b/c, Fig.1) and 5x-index (f/e, Fig.1), which, in turn, is negatively correlated with the wing-lengths (named here "Burla's rule, " which involves "Sturtevant's rule"), though statistical evidences have been scarce. The author reexamined these "rules" statistically and found them acceptable at various occasions by either the supraspecific categories involving subgenera, species-groups, morphologically good species and sibling species, or the infraspecific hierarchies such as subspecies, races, strains, individuals, and even sexual forms. Some suggestions are made on the interpretation of the "rules" from the standpoint of speciation problems and allometrical growth of wing itself or of wing membrane and veins.
