The name elongatus is preoccupied by a Fabrician species 

 (1775), and must give way to diversipiinctatus of Schrank or 

 mutabilis Germar (1821). Germar states under his description 

 of mutabilis that it is scarcely different from diversipunctatus 

 Schrank. A comparison of the two descriptions leads me to 

 believe that they are the same species. So far as I can ascer- 

 tain no one has since Schonherr's Monograph mentioned 

 Schrank's species, while mutabilis is generally considered a 

 synonym of elongatus.

The species appears to be more common in the northern 

 parts of Europe and is recorded by Zetterstedt and others from 

 Greenland, Finland, Norway and Sweden. Gebler records it 

 from Barnaul, Siberia, as rare. Walton states the Stephens, 

 Curtis, and other early English references to this species are 

 incorrect, that they did not possess "elongatus" and that it is 

 doubtful whether it occurs in the British Isles. Fowler says 

 very rare, but I believe he is referring to the earlier writers' 

 notice of the species and not to any records that were certain. 

 I have been unable to find further references to the names 

 palustris, variabilis and punctulata than those given in the 

 Dejean catalogues. It does not appear to me that the Dejean 

 species were really described. Gyllenhal's palustris is certainly 

 not this species.
