We regret that Stal has applied the name Vates to the genus Zoolea, Serv. ; this 

 interpretation causes great confusion in the synonymy of the species. The first 

 Vates described by Burmeister is V. cnemidotus ( = subfoliata, Stoll), so that the name 

 Vates of Burmeister must be reserved for this type ; while Zoolea must certainly be 

 retained for the genus of Serville. In this way all confusion is avoided.
