The muscular and ponderous appearance of this species almost unfits it for association with the 
fragile fairy forms which characterise most of the numerous species of this very beautiful genus. It 
seems to connect Ithomia somewhat with Doubleday’s genus Ituna. 
It will be seen that four of the Butterflies figured in the Plate, and many more besides, are from 
the Collection of Dr. Boisduval of Paris, whose great liberality entrusted to the care of Mr. Saunders 
and myself, not only these very rare species, but allowed me to select and bring away with me what- 
ever number we wished to illustrate from his unrivalled collection. I cannot express how much | 
value his generosity.
