The Forms of Generic and of Specific Names. 



In view of the forms of generic and specific names in arti- 

 cles recently submitted for publication in the News and in 

 other entomological journals, it seems necessary to call the 

 attention of authors and others to the rules of zoological no- 

 menclature g-overning these forms. The examples are of our

Of the International Rules of Zoological Nomenclattire 

 (Proceedings, Ninth International Zoological Congress, Mo-

 are : 



a. Adjectives which must agree grammaticalH' with the 

 generic name." 



Example: Lopidca ininiuia, xot iiiiiiiniits: Poyoiioinyia spiuitarsis, 

 NOT spinitarsus ; Johannsenia aurea, not aurei. 



"b. Substantives in the nominative in apposition with the 

 generic name." 



Example: Lopidca iiaz'ajo. L. arizona is, perhaps, admissable, but

Example : Lopidea garryae (because found breeding on the plant 

 Garrya wrightii). 



"If the name is given as a dedication to one or several per- 

 sons, the genitive is formed in accordance with the rules of 

 Latin declination in case the name was employed and declined
