I am now able to give the results of my attempts at raising the caterpillars of the three Argynnides, Cybele, Aphrodite and Diana, from the egg, this past season. In August and. early in September, 1873, females of cybele were easily obtained, and a few of aphrodite, which is a rare species here, and these were shut up in kegs, within which were placed pots of growing violets. The eggs rvere laid abundantly on the leaves and stems, and on the cloths which covered the kegs.
