This species and M. stellaia of Ecuador belong to a section of Margarornis distin- 

 guished by their cinnamon-coloured plumage and by the small spots which occupy the 

 discal portion of each feather of the breast. Their wings, too, are longer than those 

 of M. hrunnescens and much less rounded. From M. stellata, M. rubiginosa may be 

 distinguished by its paler colour both above and beneath, its more definite superciliary 

 stripes, and by the fainter pectoral spots ; but this difference is by no means well defined, 

 as the spots on the breast vary considerably in size, being nearly obsolete in a specimen 

 from Calobre and fairly distinct in our Costa Rica examples. 



M. rubiginosa has a very limited range, extending from Eastern Costa Rica to Calobre 

 in the State of Panama ; but it appears to be by no means a common bird. M. Boucard 

 obtained two specimens at Navarro in May, and Mr. Rogers others from the slopes of 

 the Volcan de Cartago or Irazu.

Mr. Sclater first described this species from specimens from Colombia, being part of 

 a collection sent to him by MM. Verreaux, of Paris, in 1856 ^. Its southern range was 

 subsequently traced to Ecuador ^ and Peru ^. Northwards it has been found in the
