65. MYIOBITJS. 205 



rufous, apical portion blackish ; edges of secondaries and tertiaries 

 somewhat rufescent, abdomen and rump brighter yellow, breast 

 more yellowish. 



Hah. Western Ecuador. 



This form appears to me to be barely separable from M. ornatus ; 

 but having only one specimen to judge from, I prefer to state the 

 points by which Messrs. Perlepsch and Taczanowski (P. Z. S. 1883, 

 p. 557) think it may be recognized.
