Owing to insufficiency of material I am not aisle to determine whether there are 

 constant differences in this species according to geographic area. All the specimens 

 from Costa Rica and Panama (thirteen in number) have the wing-bands buff; of three 

 from Venezuela two have the wing-bands pale primrose yellow, the third has them 

 yellowish buff, this coming from the same locality and obtained at nearly the same 

 date as one of the other two. In a specimen from Quito, Ecuador, the wing-bands are 

 pale buffy yellow, while in one from Peru (a cotype of L. superdliaris Cabanis) and 

 one from Yungas, Bolivia, they are pale primrose yellow or yellowish white. The 

 Bolivian specimen has the under parts much paler than any of the others, the abdomen, 

 etc., being yellowish white, the chest, etc., slightly olivaceous gray, and the upper 

 parts are darker and duller olive-green. If these peculiarities are not the result of 

 wearing or fading, this specimen doubtless represents a different subspecies. 



&As stated in the footnote above, it is probable that the South American birds 

 represent two or more forms; but not having material sufficient to enable me to define 

 them satisfactorily, I have thought best for the present purpose to throw all the extra- 

 limital references and localities together.
