[Having described the monotypical genus Xiphydria for 

 camelus L., in 1802, it was not open to Latreille to cite 

 dromedarius F. as the Type in 1810 !].

^Urocerus Jrn., represented in the Erlaiigen List by 

 camelvs L., F., and dromedarius F. is homonymous with 

 Urocerus (GfEr. 1762) Gffr-Fourcr. (1785) a monotypical 

 genus with Type: gigas L. ^Urocerus Jrn. must be re- 

 placed by Xiphydria Ltr. (1802) whose Type is camelus L. 



Urocerus Gffr. is synonymous with Sirex L., consequently 

 Urocerus is invalid in either sense.
