210 BLACKBURN AND SHARP—On Hawaiian Coleoptera. 
has been the last of the defining factors in its shaping, has not defined it in any 
way whatever. For these reasons, it has long appeared to me desirable that 
no rule should become fixed or conventional in reference to the use of references 
to generic names. In point of fact, four courses may be adopted: first, no author’s 
name need be given when a generic name is used ; and this, for many purposes, is 
the truest and most simple thing to do, though very unsatisfactory to amateurs of 
pedantry ; second, the name and reference may be to the maker of the generic 
name—this may be used in bibliographic and synonymic works; third, the name 
of the last actual describer may be given: this is perhaps the best course for 
popular works, where brevity and utility are of predominant importance over 
consistency and completeness; fourth, a history of the genus and its changes may 
be given, and the course of events by which it has come to be what it is at the 
moment of writing may be sketched. This latter is the best course, but it involves 
more expenditure of time and labour than it is worth while to devote to the object 
in the present transitional state of zoological nomenclature. For the purpose of 
this Catalogue I have therefore adopted the method of referring to the Munich 
Catalogue of Coleoptera, which will give to the student the most accessible modern 
information as to the extent of the genus and such points; and when the generic 
name is not used in the Munich Catalogue, I have referred to some other work 
where information may be obtained.
