Exotic butterflies at mid century, the 19th century that is. Just as beautiful as they are now and I hope none of these are now extinct. Taken from W. C. Hewitson’s 1856 work “Illustrations of new species of exotic butterflies: selected chiefly from the collections of W. Wilson Saunders and William C. Hewitson.” All of these plates having been printed by Hullmandel & Walton.
