I remember about ten years ago to have taken several large specimens of a Grapta, probably G. interrogationis, but they were lost without being identified. I saw no more of the species until August, 1895, when I took a fine example of the form Fabricii. It proved to be the forerunner of a “wave” of the species, and from that date until frost a number were seen, perhaps in all twenty or more, but all but two of them were of the form Fabricii. This spring I watched the hibernating butterflies closely, hoping to obtain a fertile female and rear a brood of larvæ, but although there were many G. comma and j-album, and a few progue and faunus, on the wing throughout April, I did not observe one interrogationis amongst them. By the middle of May the other species of Grapta had disappeared, or were represented by a few specimens worn almost beyond recognition.
