THE MEDITHmANEAN HfALCMMA 



NOTE; H. marginatum appears in European literatxtre chiefly

 of their followers is H. excavatum . Recently Feldman-Muhsam

 that H. marginatum is the correct name for this species although 

 reasons for so doing are somewhat obscure. 



Pomerantzev (1950) states that the name H. plumbeum plumbeum

 further investigation. Feldman-Muhsam apparently has not con- 

 sidered the possibility of this synonymy.
