This species, though referred in Mr. Doubleday's list to its proper 

 genus, is placed in ' the Genera of Diurnal Lepidoptera ' amongst 

 the Ithomice. Donovan's figure is copied from Jones's * Icones ; ' but 

 Fabricius neither described the species from Jones's figure, nor did he 

 (as Donovan states) inscribe that figure with the name P. Hippo- 

 damia : a list of species, made by Fabricius, and fastened into each 

 volume of the ' Icones,' omits P. Hippodamia altogether.
