<S ad. Differs from IJ. v. naecia by having all the upper back black with 

 mnch larger and more numerous bnffy white spots, the top of the head and nape 

 slate-grey, the rump and upper tail-coverts pale olive-brown, the tertials black 

 tipped with white, the tail-feathers ashy or olive-grey with much broader 

 (6 — 8 mm.) lilack subterminal and white apical bands, and the flanks mnch paler, 

 creamy buff. Even immature birds are readily distinguishable by the olive-brown 

 ground-colour of the head and back, and paler flanks, besides the other characters. 



Wing 58—64 ; tail 38—43 mm. 



¥ ad. In addition to the points of difference given under the heading of the 

 male, the females of II. n. tlieresae have the black malar stripe much broader tlian 

 in the typical race, and the throat pure white. 



Wing 58—62 ; tail 38—42 mm. 



Obs. I could not find any constant difference between examples from various 

 localities. Two 6i imm. from Villa Braga, left bank of the Tapajoz, agree 

 exactly with others from more western countries. All of the many females I have 

 seen have the foreneck coarsely spotted with black.
