DANAIS ALCIPPOIDES.
Plate II.—Fig. 3.
This butterfly, a variety of the Chrysippus, is rare in Teneriffe. It is found commonly in Africa and Western Asia, and is a transition variety between the Chrysippus and Alcippus. It has whitish hind-wings, rather silvery looking, with orange markings within the black border. The hind-wings have less white upon them than those of the Alcippus. It is similar in all respects and habits, mode of feeding, etc., to the Chrysippus, and is found gregariously with it. When kept collectively, about one in fifty of the chrysalides proves to be of this variety. The caterpillars of the three varieties of Danais described are about four weeks before turning to chrysalides, and remain in that state from two to three weeks before emerging to the imago.
