of the Genus Setophaga. 303 



The type species, S. I'uticilla, stands somewhat apart from 

 the other members of the genus ; and this difference has sug- 

 gested some division in the whole group. Thus, in 1850, Dr. 

 Cabanis (Mus. Hein. i. p. 19) introduced the name £M/A////>is 

 for E. lacrymosa, and Prof. Baird, in 1865, in his ' Review of 

 American Birds,-* proposed to divide the genus into three sub- 

 genera — Setophaga, 31yioborus, and Euthlypis — the type of 

 Myioborus being M. verticalis, and with it were associated 

 by far the majority of the species. 



This arrangement of Professor Baird's seems to me to give 

 a fair idea of the relationship that exists between the species, 

 and I agree with him in thinking that the differences seen 

 are of subgeneric rather than of generic value. 



The synonymy of the genus therefore stands thus : — 



(1827) Setophoga, Swains. Zool. Journ. iii. p. 360. Type 

 S. ruticilla. 



(1832) Sylvania, Nuttall, Man, Orn. i. p. 291. Type 

 S. ruticilla. 



(1850) Euthlypis, Cabanis, Mus. Hein. i. p. 19. Type 

 S. lacrymosa. 



(1865) Myioborus (as a subgenus), Baird, Rev. Amer. B. 

 pp. 237, 257. Type S. verticalis. 



I recognize fifteen species of Setophaga, specimens of all 

 of which I have before me. They may be arranged as 

 follows : — 



A. Sexus dissimiles : alls longiori"bus ; rostro debili, 



rectricum lateralium apicibus nigiis ; speciilo 



alari rubescente ; ventre albicante. {Setophmja.) 1. ruticilla. 



B. Sexus similes : alis brevioribus, magis rotimdatis ; 



rostro debili ; rectricibus lateralibus fere totis 

 aut in parte terminali late albis. (Myioborus.') 



a. Supra nitenti-uigra ; speculo alari late albo j 



abdomine coccineo 2. ^j/e(!«. 



b. Supra scliistacea aliquando olivaceo tincta : spe- 



culo alari nullo. 

 a'. Mento et gida nigricantibus : 



abdomine rubro 3. miniata. 



abdomine aurantiaco 4. mircmtiaca. 



abdomine flavo , 5. verticalis. 



V. Corpore subtus omnino aureo-flavo. 



a". Pileo toto nigro, oculorum ambitu flavo . . 6. melanocephala.
