KEY TO THE SPECIES AND SUBSPECIES OF MYIOZETETES. l) 



a. A broad white superciliary stripe, extending above auricular region to occiput. 

 b. Distal secondaries and proximal primaries distinctly edged with 'rusty; sides of 

 pileum, auricular region, etc., sooty blackish; crown-patch more y(>llowish 

 orange or orange-yellow. {Myiozetetes cayanensis.) 

 c. Smaller, with less of rusty on wing. (Amazon Valley to western Ecuador, 

 Colombia, Venezuela, etc., and Panama.) 



Myiozetetes cayanensis cayanensis. (p.444). 

 cc. Larger, with more of rusty on wing. (.Soutiiern Brazil. ) 



Myiozetetes cayanensis erythroptei"us ( extralimital ) .c 

 bb. Distal secondaries and proximal |)rimaries not edged with rusty; sides of pileum, 

 auricular region, etc., more or less grayish; crown-patch more reddish orange 

 or orange-red. 



aMusdcapa sulphurea Spix {Myiozetetes sulphureus Cabanis and Heine, Sclater, and 

 others) is certainly not congeneric (see ' 'key" to the genera, p. 344). Elxnia lutciven- 

 tris Sclater (Myiozetetes luteivcntris Sclater) I have not seen. 



bl have not seen the following species, referred to this genus by Doctor Sclater: 



Elx7iia luteiventris Sclater, Proc. Zool. Soc. Lond., 1858, 71 (Rio Napo, e. Ecuador; 

 coll. Verreaux). — Myiozetetes bUeiventris Sclater, Cat. Am. Birds, 18G2, 219; Proc. 

 Zool. Soc. Lond., 1871, 754 (e. Ecuador; Rio Negro; Rio Madeira; Cayenne); Cat. 

 Birds Brit. Mus., xiv, 1888, 164 (Oyapoc, Cayenne; Rio Napo and Sarayacu, e. 

 Ecuador); Pelzeln, Orn. Bras., ii. Abth., 1869, 109 (Maribatanas, n. Brazil). 



Myiozetetes sulphureus of authors (Muscicapa sulphurea Spix, Av. Bras., ii, 1825, 

 16, pi. 20) I consider not a member of this genus and have made it the type of a new one 

 {Tyrannopsis Ridgway, Proc. Biol. Soc. Wash., xviii, Sept. 2, 1905, 209). 



The young of the different forms of Myiozetetes are so poorly represented in the series 

 oi specimens examined that I am unable to include them in the key.
