On 13th Sept., 1884, I received from Mr. James Fletcher 22 larvæ in hibernation, part of a lot sent him shortly before by Rev. Geo. W. Taylor, of Victoria, V. I. The larvæ, on exposure to the light, moved about, but refused to eat Chelone glabra. I placed them in cellar, and in October forwarded to Clifton Springs, N. Y., with larvæ of other species, to go in the “cooler.” On 7th March, I received them again, ancl found about one half to be alive. These I put in the ice house till I could get leaves of the food-plant. In last days of April they were brought to the house and given Chelone, the living larvæ now being reduced to six. On the third day, I noticed that the leaves had been eaten, and three or four days later the larvæ looked healthy and had recovered the length and diameter which they had on 13th Sept., larvæ always shrinking much during hibernation.
