This species and WM. stellata 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. brunnescens and much less rounded. From J. 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 byno meansa 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 18561. Its southern range was 
subsequently traced to Ecuador? and Peru’. Northwards it has been found in the
