3. A generic name need not be accompanied by any verbal de- 

 scription. It is considered to be founded in the sense of rule 2 if 

 accompanied by the names of one or more described species in a pub- 

 lished article. 



If there is no species mentioned, or those mentioned are not then or previously 

 characterized, the name is invalid, even though accompanied with a description. 



4. Names proposed as subgeneric or subspecific are to be treated 

 as if of generic or specific value. 



5. A specific name to be valid must be accompanied by a descrip- 

 tion or a figure or such data as will separate it from the other species 

 of the genus then known. 



The citation of type specimens in a collection does not constitute definition. We 

 regret that it is impossible to differentiate between adequate and inadequate descrip- 

 tions. The only place where it seems that a line can be drawn that is not too much 

 subject to individual interpretation is between an attempt at a description, however 

 feeble, and none at all. 



6. Superfamily, family, subfamily and tribal names shall be formed 

 from the oldest valid generic name included in their respective groups 

 by the following endings : -oidea, -idse, -in?e, and -ini respectively. 



If the genus on which the higher name is founded becomes invalid, the higher 

 name is to be changed, following that of the next oldest genus and not the one that 

 may be substituted for the oldest.
