156 Bangs Seven New Subspecies of American Birch. 



specimens, and called attention to the fact that the place whence they 

 came was the most northern from which the species had been recorded. 

 Since then I have examined a number of additional skins of true C. lavinia 

 from all of which the Honduras bird differs so much in size and length of 

 bill, that it must certainly be regarded as a well-defined subspecies quite 

 worthy of recognition by name. 



Phcenicothraupis rubica confinis subsp. nov. 



HONDURAS ANT TANAGER. 



Type from Yaruca, Honduras, cT adult, No. 10,034, coll. of E. A. and O. 

 Bangs. Collected February 25, 1902, by W. W. Brown, Jr. 



Characters. Adult cT intermediate in color between true P. rubica of 

 South America and P. rubica vinacea of Costa Rica to Panama much 

 darker, more vinaceous red than in rubica, but lacking the dusky mottling 

 on throat of vinacea. Compared with the male of P. rubica rubicoides of 

 southern Mexico, the new form is much deeper red and vinaceous below 

 and much redder, less brownish above. Adult $ quite different in color 

 from that sex in the allied forms much greener than in true rubica with 

 little of the reddish brown shade so marked, especially on tail, in that 

 form ; crown patch clearer, paler yellow. Not so greenish in general color 

 ation as vinacea with the throat much yellower, wholly lacking the dusky 

 mottling. From the female of rubicoides the new form differs in much 

 greener less brownish general coloration and in having the yellowish 

 throat patch much more clearly marked and much yellower, less brownish. 



Size a little less than in P. rubica rubica. 



MEASUREMENTS. 



Remarks. The six specimens on which this well-marked new form is 

 based had lain in my collection identified as P. rubica rubicoides ever since 

 Mr. Brown sent them in, until last winter, when E. W. Nelson saw them 

 and instantly declared them to represent a new form. He very kindly 

 helped me compare them with ample material, when it at once became 

 evident that the form from the coast region of Honduras is quite as strongly 

 characterized as any of the geographical races of Phcenicothraupis rubica.
