in the female. A young male of I. pnstulatus before me, has the back 

 similarly marked, but the spots are smaller and the upper plumage is 

 more olivaceous. The general plumage of the adult female and young 

 male of /. pustulatus, is much duller and more olivaceous thau that of the 

 new species of corresponding sex and age. 



Habitat. "Tehiiantepec (Tuchitau)." 

 Collected by Prof. F. Suinichrast. Type in Museum of 

 Smithsonian Institution. 



Remarks. The adult male above described, was in a col- 

 lection recently received from Prof. Sumichrast, the others 

 were in his former consignments and have been considered 

 /. pustulatus, the markings on the back of the female and 

 young male being somewhat like those of that species; but 

 the two are shown to be very distinct on comparing the 

 adult males — the back of the present species is crossed by 

 a broad black band, whereas that of I. pustulatus is orange, 

 the centres of the feathers marked with narrow ovate spots 

 of black ; in the new species the deep orange color above 

 continues without change until it joins the black of the back, 

 in /. pustulatus the deep color is restricted to the fore part 

 and sides of the head. This species really comes nearest to 

 the bird from Guatemala named /. sdateri by Mr. Cassin 

 (which he says is /. mentalis, Scl. nee Less.) ; from this it 

 differs in being smaller and of a much deeper orange color, 

 the outline of the bill is more curved, that of /. sdateri 

 beinof nearly straiiiht ; the bases of the feathers which form 

 the black mantle are white tinged with yellow in /. sdateri, 

 in /. formosus they are grayish-white except immediately 

 adjoining the black ends of the feathers, where they are 

 orange, this color showing a little on the edges of the feath- 

 ei;s of the upper part of the mantle. 



This bird is almost a miniature of/, gidaris, differing only 

 in the mantle of that species being of a uniform black, and 

 having the bases of the black feathers grayish-white, with- 

 out any portion of them yellow.
