On the 30th of July Mr. T. L. Mead, at Coalburgh, took two females of Grapta Dryas and tied them in a muslin bag to a branch of Hop-vine. The result was a large number of eggs, laid on the leaves and in the bag. On the 5th the eggs were all hatched. The larvæ we carried through safely, and on the 21st the first ones began to change to chrysalids. In course of the next three days all were changed, upwards of sixty. Towards maturity some of the larvæ were white, as represented in the plate of Dryas, in the “Butterflies of North America.” The others were black, like the larvæ represented in plate of Comma in the same volume.
