In June Papilio Turnus Linn, and Danais Archippus, Fab., were unusually abun-* dant. On the 25th of the month I found Archippus larvae in the second and third stages. At the same time the female butterflies were hovering about the milk- weed in numbers, laying their eggs one here and one there on the plant. The more advanced larvae were full fed on the 4th of July, and suspended themselves for the pupal change. A day later they cast the last caterpillar skin, working it upwards till it reached the cremaster, when a succession of convulsive twists dislodg- ed it, and it fell to the ground. The abdominal seg- ments were then drawn up and shaped into the rounded summit of the very beautiful pupa. The pupa changed from green to a rich mahog- any brown in the night of Fjg. 64.—Hybernia tiliaria : the winged male and wingless July 16th-17th, and the per- female moths; larvae of various sizes. feet insects appeared in the afternoon of the 17th. Butterflies of this species were on the wing throughout the month of August In July Chrysopltanus epixanthe, Bd., and Lee. was unusually abundant at the Gomin Swamp. In August larvae of Grapta interrogationis, Fab., were found feeding upon hops which shaded the verandah of the country residence of the Hon. Richard Turner, on the Island of Orleans. In this month I saw Pamphila Manitoba, Scud, on the Heights of Levis, but not in, numbers. In the Society's Annual Report for 1897, on page 73, I gave an account of the saw-fly larvae that fed on poplar, and a description of the perfect insect. Mr. Ashmead has since identified this for me as Nematus luteotergum, Norton. On the same page I described saw fly larvae that fed on Comus. They buried them- selves in October, and I found some of the larvae quite fresh in the Spring, but they failed to pupate, and perished. Last fall I obtained a new batch of the lar
