Four darker is of a uniform orange color with a black head,but it becomes dull brown before tlje tirst moult,though the longitudinal stripes and black spotsare only visible after said moult has taken chrysalis (Fig. f>i h), averages inchin length, and is as variable in depth of ground-color, as the larva. The general color is lightbluish-gray, more or less intensely speckledwith black, with the ridges and i)rominenccsedged with but! or with flesh-color, and having larger black dots. [Kig. r«.]. u— t;olors—Black and white. The female butterfly (Fig. 53), as was statedin our last number, (p. GO) differs remarkablyIrom the male which we represent at Figure will be seen, upon comparing these figuresthat the ? is altogether darker than the (?•This sexual difference in appearance is purelycolorational, however, and there should not bethe difference in the form of the wings whichthe two figures would indicate, for the hindwings in our g cut, are altogether too shortand rounded. This insect may be found in all its differentstages through the mouths of July, August andSeptember. It hybernatcs in the chrysalisstate. We do not know that it feeds on any-thing but Cabbage, but we once found a ^chrysalis fastened to a stalk of the common net-tle, (Solanum caroUnense) which was growingin a cemetery with no cabbages within at leasta quarter of a mile.
