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 Nature 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.—A pha 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 Nature of 1755, 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 algérien” 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-
