In Dr. Dyar's “Preliminary Notes on the Larvæ of the Genus Arcta” (Jour. N.Y. Ent. Soc., March, 1900), some interesting remarks are made in reference to the larvæ of Arctia virgo, as to the stage in which the larvæ hibernate, and if they ever posses a dorsal stripe.Through the kindness of the late Mr. T.G. Priddey, of Toronto, we received on the 10th April, 1901, three larvæ of A.virgo, collected by him on the 5th April. Writing under date of the 8th April to Dr. Fletcher, Mr. Priddey says: “I shall probably get more larvæ, but even now the bank under the grass where they hibernate is quite solid ice.” The three specimens only moulted once before maturity, viz., on the 26th April, 30th April, and 8th May, respectively; so these, at any rate, hibernated in the penultimate stage. Mr. Dwight Brainerd tells me that “ at Montreal, A. virgo generally hibernates in its second to las skin; that is, it sheds its skin twice in the spring before going into pupation.” He also states that he has found specimens in the fallin the penultimate stage. In the Annual Report of the Entomological Society of Ontario for 1869, on page 13, Dr. Fyles mentions that in the spring of 1891 he collected larvæ of this species at South Quebec, which moulted on the 4th May and again on the 20th May, the moths emerging on the 10th July.
