Body tubercles very much flattened, semitransparent, two subdorsal and a lateral one upon each abdominal segment, each bearing a slender, nearly colorless hair. Tips of true legs dark brown, well developed prolegs on the third to sixth and loth abdominal segments. The tube of this larva w^as first described by Clemens under the name of C a s t a s t e g a aceriella. It was later referred by Dr Dyar to Clemens's species originally named H e d y a s i g n a t a n a. Clemens's descrip- tion of the adult follows : Fore wings white, marked with dark brown. The basal patch is distinct, dark brown and consists of three or four an<ai- lated lines, the exterior being the broadest. The dorsal patch is white, extended to the costa, contracted in the middle of the wing and is traversed by a few broken, indistinct, brownish lines. The central fascia is dark brown, rather indistinct, and contains three black dashes opposite the ocelloid patch. Fig. which is white and rather indistinct. The costa is marked with dark brown streaks and near the tip are three or four geminated white spots, the dark brown streak which separates the two nearest the tip of the wing is extended along the hinder margin to the ocelloid patch. At the extreme tip is a black Semicircle in the cilia, upon a dark brown ground. Hind wings dark fuscous. Remedial measures. Arsenical poisons applied to the underside of the leaves should check this species Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum; University of the State of New York; Metcalf Coll
