Type, 0. antiqua Lin., from Europe. Sir Geo. Hampson has recently 

 substituted the name of Notolophus Germar, which is unfortunate, and used the 

 name Orin/ia for the genus hitherto known as Basychira. which seems mischievous. 

 When a name has been almost universally employed in one sense for about a 

 eentuTV, to employ it in a different sense, even if it were not so changed by the 

 adoption of an artificial mode of "fixing the type," is to reduce nomenclature 

 into confusion. No one can tell, unless he knows the particular predi- 

 lection of the author, what the name used by him really means.
