The name Estheria was originally proposed by Dr. Riippell for a species 

 brought from Abyssinia; its description, with figures of typical species, 

 appeared in the above cited work. In the same year Mr. Audoin (Annales 

 Soc. Entom., vol. 6), proposed that of Cyzicus for similar species, without 

 a generic description. The simultaneous publication of these two generic 

 names for the same genus lead Mr. Joly (Annales Sci. Nat., 2d series, vol. 

 17, 1842, p. 293), to propose that of Ittaura. 



Estheria is now generally used by authors.
