 Eristethus Agassiz, 1846, p. 143. [Emendation.] 

 Notes : In 1870 Crotch stated that Eristhetus was an error for Evaesthetus 

 Gravenhorst. But Mannerheim states that Euaesthetus was a lapsus 

 calami for Eristhetus. The latter is therefore an emendation at least In 

 Mannerheim. There seems to be no reason for not treating the earlier 

 publications the same way.
