 Variant spellings — Continued 



Xautholinus Mulsant and Rey, lS77b, p. 266. 

 Notes : The confusion over the author of this genus has led to differences in 

 usage. The true genotype is the same as that of Oyrohypnus, which is an 

 older name and therefore replaces Xantholinus. The large genus previously 

 known as Xantholinus may now be called Megalitius, while tlie old subgenus 

 Xantholinus must be called Idiolinus.
