DANAIS DORIPPUS v. KLUGII.

This is the fourth variety of the genus Danais, and is authentically claimed as one of the Teneriffe butterflies, though by no means commonly found. It varies from the Chrysippus in having no brown apical patch on the fore-wings, and it also has no band of white spots across them. It measures from two and a half to three and a half inches across the wings. It is not an inhabitant of England, but is commonly found in North Africa and Western Asia.
