Excerpt from The Entomologist's Record and Journal of Variation, Vol. 42: January, 1930 The imagines, derived from eggs laid by the first generation in May appear in England in July and August, and differ from those of the first generation in having the apical blotches very dark, their extreme tips only being slightly irrorated with white, and indented internally along the nervures. The hindwings beneath are pale yellow and only slightly dusted with black scales. It is difficult at present to state the range of variation in this generation in England, for it is poorly represented in the collections we have seen. This is due partly to neglect of this common and apparently. Uninteresting species during the height of the season, and partly to the fact that the larvae are not found in abundance in gardens, as they are late ln the season. The autumn larvae on the other hand are often very abundant in gardens and can be collected easily in large numbers. Consequently the first generation and its aberrations are better represented.
