48 The Butterflies and Moths of Teneriffe. 



When it changes to the pupa state it resembles closely 

 the bright green chrysalis of its companion, only it is 

 not quite so large. 



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 collec- 

 tively, 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.
