Upper Side, The head and body are of a dark brown. All the wings are of a yellow brown orange, besprinkled over with black spots. The under side of the superior wings is paler than the upper side. The inferior wings are of a dark red brown, having some yellow spots: there are besides, situate in the centre of the wing, two pearl-like or silver spots ; and seven of the same kind placed in a row, or like a border along the fan edge. They are taken in woods, and appear about the middle of May. Expansion of the wings If—2 inches. This species is stated to be double brooded ; the first brood appearing in May, and the second about the beginning of autumn. {See Bree in Mag. Nat. History, No. 21.) The caterpillar is black with two spotted orange stripes on the back ; it feeds on various species of violets. The butterfly is one of the commonest of the fritillaries, occurring plentifully in different parts of England. A singular circumstance has been observed by M. Vandouer of Nantes, relative to this species (recorded in the Annals of the Linnsean Society of Paris): having procured a number of eggs, deposited by a female, he found that the young larvae, (which he fed with Viola odorata) at the end of June fell into a state of lethargy, in which the majority remained until the following spring, some however revived at the commencement of August, and commenced feeding with avidity, they then changed their skins for the fourth and fifth times, and became perfect insects at the end of the same month. This observation explains the reason why the butterflies are so common in the spring, whils
