Syst. t. 1. p. 5. 2280. n. 473._ * * * * * The delineations of the very beautiful butterfly that appears in the annexed plate, are copied from a specimen in the cabinet of the late worthy president of the Royal Society, Sir Joseph Banks. Fabricius had previously observed and made known throughout Europe the description of this species with many others of the Banksian Cabinet, but the figures of it now submitted to the amateur are the first that have appeared.—When we consider the celebrity which the entomological writings of Fabricius have acquired it may be satisfactory to learn that the delineation now before us is copied from the individual specimen which Fabricius had described, and that no other figure of this very interesting Papilio is extant.
