(2) No new genus will be published, that is not based on a 

 described species. 



(3) Rules 1 and 2 also apply to subgenera. 



(4) No new species may be described without comparing it 

 with some other described species, or stating wherein it differs 

 from other members of the genus. 



(5) When a new species is based on specimens from several 

 localities, it must be explicitly stated which is the type locality. 



(6) When a new species is described the data concerning 

 localities and collectors must be given in full so far as known. 

 This is also strongly recommended in the case of all new records. 

 If the locality, collector, etc., are not known, it may be well to 

 say so, although this may be taken for granted if the writer is 

 known to be careful in citing data. 



(7) It is impossible to avoid all errors in spelling, grammar, 

 etc., but so many of them have appeared in recent years, that 

 American entomologists have some reason to feel ashamed. 

 It would be easy to compile a list of scientific names which must 

 be retained in our lists, although faulty to the extent of being 

 offensive. This is true in spite of the freest recognition of the 

 fact that scientific latin is a living and growing language, and 

 must include many words unknown to the ancients. No rule 

 can cover this difficulty, but it might be worth while to collect 

 every year a list of these criticisable productions, and set them 

 forth as a warning to authors and editors alike. 



(8) It is not permitted to publish new varieties as binomials; 

 the trinomial must in every case be written out.
