I am quite satisfied that the figure given by Drury was taken from a specimen which 

 had the hind wings mutilated, and the head replaced by that of a Papilio. Drury gave 

 China as the locality of his specimen, which is also clearly erroneous ; but whether the 

 specimen had been brought from Madagascar or from some part of the eastern coast of 

 Africa is uncertain. In the latter case his insect may be geographically distinct from 

 the Madagascar individuals ; and this would enable us to account for the variations in 

 the markings of the wings pointed out by Swainson, Guenee, and Boisduval. Until, 

 however, we receive individuals agreeing with Drury 's figure, I should be inclined to 

 think that the variations pointed out resulted from the evidently imperfect and 

 partially rubbed condition of Drury's insect. 



According to M. Sganzin, who captured numbers of C. rhipheus in Madagascar, the 

 small neighbouring island of Sainte-Marie possesses a smaller species, thus noticed by 

 him in his communication to M. Boisduval : — " II existe aussi une petite espece que je 

 crois tres-differente de la premiere ( U. rhipheus). On ne I'a pas rencontre a la meme 

 epoque, et je ne crois pas qu'on la trouve a la grande terre ; je ne I'ai jamais vue qu'a 

 Sainte-Marie; elle parait en mars et avril," the true U. rhipheus appearing in the 

 winged state in September.
