The reader is probably aware that while many minerals and a certain number of animal substances are employed in coloring, the largest portion of our dyes are borrowed from the vegetable kingdom. NOTE M. SULPHUR, OR BRIMSTONE BUTTERFLY, (_Gonepteryx Rhamni_,) p. 74. “This is the Brimstone Butterfly, which, gaily painted, “Soon Explores the tepid noon, And fondly trusts its tender dyes To feeble suns and flattering skies.” “It has been supposed by some that this early visitant, (also a late one,) is, like the above, a winter survivor; but from the trim of his yellow robes, usually so fresh and glossy, it would seem more likely that, instead of being laid up—not in lavender, but perhaps in ivy—they are of the newest spring fashion. Be this as it may, he is the very pink, or, as he has been more properly considered, the very primrose of Papillons, sometimes to be seen like a living shadow of the primrose’s self, fluttering beside it in the sunny hedge-row, or the sheltered copse. We may know him by the cut of his bright, sulphur-colored pinions—each, instead of being rounded, ending in a smooth tail-like angle. “Of all the wings of the butterflies, these bear perhaps the closest similitude to floral productions, and on each, as if to perfect the resemblance of the delicate, flower-like coloring, is a reddish spot, an exact copy of that often produced by decay or accident on the surface of a yellow petal. In the beautiful raised bearing of their reverse, the pinions of the “Brimstone” are no less correspondent with the same; but those of the female, which, instead of yellow, are of a greenish white, resemble perhaps yet more nearly, the leaf of a poplar on its under side. The dye of the antennæ—that purplish pink so frequent upon tender leaf and flower-stems—also the clothing of the body, a soft satin down like that by which stalks and seed pods are so often covered, are all alike accordant with the floral character of this most elegant flutterer of the spring. This pretty butterfly comes of a pretty caterpillar, with a smooth green coat, dotted or shagreened with black, and marked by a whitish line along the back and sides. It is said to feed usually on the leaves of the hawthorn and alder.”—_Acheta Domestica._ NOTE N. FURZE, (_Ulex Europæus_,) p. 77.
