This interesting caterpillar, thus far content to remain upon the plant where its parent placed it, now grows restless, leaves the seed-pods, descends the flower-stalk, sometimes forsakes tlie plant entirely. In any case it choses some secluded spot on a lower hranch of its food plant, the dead limh of an adjoining tree, or a neigh- boring fence-hoard, as a place for its subsequent transformations. In the vivarium they adapt themselves to the circumstances. One we watched chose the wire screen of a breeding- cage, another the handle of a silver cnp which held the food plant. In nature, however, these caterpillars seem to show a decided preference for slanting objects when selecting a loca- tion for pupation.
