5 LLOYD'S NATURAL HISTORY. 



Urania, Guenee, Uran. et Phale*n. i. p. 10 (1857). 



The species of this splendid genus, which includes perhaps 

 the most beautiful Moths known, may be at once distinguished 

 from Cydimon by their shorter and broader wings, and by the 

 hind-wings throwing off a rounded projection at the extremity 

 of each nervule, which intersects it, those at the extremity of 

 the median nervules forming rather long tails, of which the 

 uppermost is the longest. They are found in Madagascar, in 

 the adjacent island of Sainte-Marie, and in Zanzibar, but not 

 on the west side of Africa, unless the small specimen figured 

 by Drapiez in 1819 under the name of Urania promethens 

 (Ann. Sci. Phys. ii. p. 356, pi. 30, figs, i, 2) was really ob- 

 tained from St. Helena. No doubt all the larger and more 

 conspicuous insects indigenous to that island must have 

 become extinct, with the almost total extermination of the 

 native vegetation, and so much has disappeared even within 

 the last hundred years, that it is by no means impossible that 

 an indigenous species of Chrysiridia may have inhabited the 

 island during the last century.
