2. Species name, usually a Latin adjective agreeing in gender with the 

 genus name and never written with a capital except when derived from a 

 proper name and usually not even then. 



3. Authority, the name of the first describer of the species, usually ab- 

 breviated and inclosed in parentheses if the species was not originally placed 

 in the proper genus. 



When varieties or subspecies are indicated, the name is formed precisely 

 like the species name and given immediately after it followed by the au- 

 thority of the variety and not that of the species. Sometimes the variety 

 is considered subordinate to subspecies, and then the varietal name stands

Groups higher than species are often called subgenera. Such names are 

 formed precisely like generic names and given in parentheses between 

 the genus and species name. 



Names of groups higher than genus never appear as part of the name 

 of a species and are almost uniformly derived from genus names by the 

 substitution of a termination as -idae for family and -inse for subfamily 

 -oidea has served for superfamily, tho the shorter -ina is to be preferred. 



Order names are not derived from generic names, tho most of them have 

 the common ending -ptera.
