[...] This malformation is interesting as showing in the same specimen the instability of this character the strong tendency to the assumption of the male form of wing exhibited in the lengtheing of the lobule next in order and the unmistakable reversion' to the rounded form of wing in the suppression of the rudimentary tail. [...] In this specimen both the wings of the left side are truly female but on the opposite aide the posterior portion of the fora-wing from the first discoidal vcdnlet to the inner margin on the upper side only and the anterior portion of the hind-wing frothe costal margin to the second branch of the sub.cestal on both sides exhibit the masculine livery not unminglod with female characters (Conf.
