Although the name frequently occurs in Continental Collections 

 generally attached to some form of P. casertanum, this species must 

 be rare on the Continent, for the only living examples met with so 

 far were from Bornholm [Lynge Coll.]. 



In the fossil state it has been reported from the Holocene and 

 Pleistocene of Denmark [Johansen (85, p. 9)] and seen from the 

 Pleistocene (Campinien) of Soignies and Brussels [Mus. Hist. Nat. 

 Brussels].
