. Annual report. Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. 16 THE EEPOKT OF THE No. 36 Coucerniiig the first to arrive of the migrants from tlie soiitli I have made the following note:— June 15th. " Two specimens of Anosia were seen flitting about a few milk- weed plants on the Old Belt Line, near the Humber; one of the butterflies ap- peared to be ovipositing, but the eggs could not be found.'' The above apparently represents, in general, the date of the first appearance in Ontario of this butterfly, since it agrees with that noted by other observers. In 1900, Mr. C. W. Nash, Toronto, states that he saw the Monarch first on June ] 1th, and in 1901, Mr. J. A. Moffat, London, noted its arrival there on June 12th. While the middle of June may be taken as the average date of their arrival in this Province, there must be at least isolated butterflies that return much earlier. With reference to this 1 find in my notes:— June 19th. " Mr. Martin saw, on milkweed plants, a nearly full-grown Monarch larva, also a much smaller one." Later in the day we found the larger larva but did not get the smaller. The one we captured was one and three-fourths inches in length. The egg from. Fig. 1.—Gall produced by Neuroteras flavipcs Gill on Bur Oak, Quercus viacrocarpa Michx. which this larva emerged must have been deposited the end of ^lay or very early in June. There are notes under two other dates in June. June 21th. " Anosia butterflies plentiful around the milkweeds at Mimico Creek." June 27th. " In the same locality as the preceding, caught three males and two female butterflies. These specimens were all much faded and worn, the wing margins were also badly torn. The butterflies were frequently mating at this time." Nothing of interest appears to have been observed for a month, as the next note reads:—- July 27. "Many M'^narch butterflies oxipositing, all the specimens captured were faded and t
