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.
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.
