INTRODUCTION. 



1. No person nor committee has authority to interpret, limit, or 

 extend the precepts here laid down ; every user interpreting the rules 

 for himself. 



2. The word "VALID" as used in this code of rules means 

 "WITH STANDING IN NOMENCLATURE," and the word 

 "INVALID" means "WITHOUT STANDING IN NOMEN- 

 CLATURE." 



Note. — Names in synonymy, or ones preoccupied, as well as names 

 in use may be valid, having standing as defined above. Invalid 

 names are nomina nuda. 



BINOMIAL NOMENCLATURE. 



3. All species of insects are to be named according to the binomial 

 system of nomenclature as applied by Linnaeus in the 10th edition 

 of his Systema Naturae of 1758. This consists of the generic, or 

 general, name of one word, and the specific, or trivial, name, of one 

 word, or a hyphenated word. 



Example. — Alpha alba L. 



Note. — If a "binary" (two categories whether named or not) sys- 

 tem were adopted as the basis of entomological nomenclature we 

 would be compelled to go back to the first edition of Linnaeus' Sys- 

 tema Naturae of 1735, as the use of the generic name (independent 

 of the specific name) dates from that work. 



4. The nomenclature of any author who has not followed the bi- 

 nomial system is to be ignored. Accidental binomials occurring in 

 the works of such authors are to be rejected as invalid, and accidental 

 trinomials in works otherwise binomial are not to be excluded. 



5. The use of a French binomial (or other language not in Latin 

 form) does not validate the name. Thus "Acridien algerien" Is not 

 available under the code. 



6. The following cases shall be considered as complying with the 

 requirements of binomial nomenclature: 



(a.) Where the Latin name of the foodplant has been used as a 

 part of the name of an insect such name shall be considered a bi-
