The name gryneus Hbn. will apparently stand as the correct name 

 for the ordinary eastern or "type" form of this species. Iliibner sunk 

 the name damon Cram, creating the name gryneus. There is no state- 

 ment of why this was done, altho Hiibner undoubtedly considered 

 damon Cram, a homonym. The Encyclopedic Methodique definitely 

 states "Nota. Nous avons change le nom de Cramer pas qu'il y a un 

 autre polyommate qui porte le nom de Damon." It was not recognized 

 that Hiibner had already given a second name to this species and while 

 this action undoubtedly sunk damon Cram, as a homonym of damon 

 Schiff. the insect had another name which could be used. The Inter- 

 national Rules of Zoological Nomenclature definitely state that a re- 

 jected homonym can never again be given status (Article 36). The 

 name dama^tus simply remains a synonym but should be credited to 

 Godt. & Latr. While Latreille in the introduction to volume IX of 

 the Encyclopedic Methodique appears to credit the work on "Papilio" 

 to Godart, he states also, "i\I. Godart a toujours demande mes conseils 

 dans tout les difficultes qu'il a rencontrees." In the quotation given 

 above which sinks damon Cram, as a homonyn, nous is used and not 

 je, evidently intending Latreille should have joint authorship. 



The form with the dark brown nearly unicolorous upper surface 

 from the east will have to be called smllacis. The original description 

 and figure while poor show beyond question that this was the form 

 before Boisduval and Leconte. 



Specimens in the Harris Collection, apparently the types of auhiirn- 

 iafia, represent both gryneus and smllacis. 



The eastern race appears to range at least as far west as the 

 Mississippi River, one specimen of M. gryneus in the Barnes Collec- 

 tion being from Vicksburg. Miss. 



In Texas the western race castaUs Edw. is found. It is very 

 "close" to the eastern race. The main difference seems to be in the 

 position and shape of the inner medial spot on the secondaries below.
