The synonymy of this species is apparently very much con- 

 fused. Dahlbora considers it to be identical with the Crabro 

 striatus of St. Fargeau : that it cannot be so is proved by the 

 position of the stemmata, in a curve ; in the genus Crabro of 

 St. Fargeau they are in a triangle. Since the remarkable stria- 

 tion of the mesothorax, transversely in front and longitudinally 

 behind, is not mentioned in the descriptions of St. Fargeau's 

 Crabro, Ceratocolus, or Crossocerus striatus, it is impossible to 

 adopt either of the species as identical with C. Lindenius.
