Remarks. Not all the localities enumerated in the Crust. 

 Is. Terr. pag. 222 are belonging to this species. The localities 

 from the South coasts of the Mediterranean Sea certainly arc to 

 refer to this species while the localities from France belong to 

 Ph. Couchi Kinah., a species very different from Ph. longicornis 

 B.-L. and perhaps identical with Ph. cellaria Dollf. — The de- 

 scription in 1. c. is made after genuine specimens of Ph. longi- 

 cornis B.-L.
