band and superciliaries, and in the absence of well-defined wing- 

 bars. It is also somewhat smaller, as compared with Bogota 

 specimens identified as O. gratiosa by Dr. Sclater. 



This species is represented by four specimens, taken as fol- 

 lows : San Lorenzo, altitude 7000-7500 feet, May 12 and 13 ; 

 El Libano, altitude 6000 feet, May 3 ; Valparaiso, altitude 5500 

 feet, March 8.

Type, No. 72728, $ ad., Valparaiso, altitude 5500 feet, April 14, 1899 ; coll. 

 H. H. Smith. 



Above dark clear greenish olive, blackish on the head, fading on the hind 

 head into the uniform deep greenish olive of the rest of the upper surface ; 

 wings and tail dusky, the latter strongly edged with olive ; wing-coverts and 

 outer edge of secondaries, except basally, broadly edged with greenish yellow ; 

 primaries 2-5 similarly edged for the proximal half of their length, the others 

 wholly black externally, like the proximal third of the secondaries, forming 

 a conspicuous wing pattern of black and light greenish yellow ; bend of 

 wing and under coverts bright greenish yellow ; frontal band and super- 

 ciliaries clear white ; sides of head grayish white, except a small black 

 loral spot ; ear-coverts dusky ; below throat and fore neck white or greenish 

 white ; breast and sides gray with an olive tinge, slightly flammulated with yel- 

 low ; abdomen and crissum greenish yellow. Bill and feet deep black. Wing, 

 54 mm.; tail, 46 ; tarsus, 18 ; culmen, 14. 



Ochthceca olivacea bears a general resemblance to O. diademata, 

 its nearest ally, but differs from it in having the frontal band and 

 superciliaries clear white instead of yellow, and in the rump be- 

 ing deep olive green like the back instead of rufescent. It is re- 

 presented by five specimens, all taken at Valparaiso, April 5 and 

 14, 1899.
