I have used this name because no other would be understood 

 and because others use it in this country. Living in Sweden 

 Linnaeus gave the specific name helxines to a metallic green 

 flea-beetle with testaceus legs and antennae, living on buck- 

 wheat. Usage has since attached this name to various 

 species but in the European catalogues they no longer cite 

 Linnaeus, but use the name as a suppressed synonym under 

 various species and ascribed to diverse subsequent authors. 

 The paradox' is that the European coleopterists do not use 

 the Linnaean name but that we apply it to a complex of 

 species which we do not distinguish and no one of which can 

 be the species to which Linnaeus gave the name.
