C. pulchellus is very rare in Denmark, only one specimen, a male, 

 has been taken on Bornholm at Allinge in July 1883 (H. J. Hansen). 



Geographical distribution : — Europe down into Spain ; towards 

 the north in Denmark, and if Zetterstedt's taeniomerus var. b is this 

 species, which is very probable, it was known to Zetterstedt from the 

 southern Sweden; that it occurs there is also stated by Wahlgreen 

 (Entom. Tldsskr. Årg. 33, 1912, 33, 3.), but he declares nothing about 

 the synonymy.
