Sp. Cuar. Bill nearly as long as the head ; upper parts generally rather clear olive- 

 green. Head with four black stripes and three brownish-yellow ones, namely, a black one 

 on each side of the crown and one from behind the eye (extending, in fact, a little anterior 

 to it), a broader median yellow one on the crown, and a superciliary from the bill. Under 

 parts pale brownish-yellow, tinged with buff across the breast and with olivaceous on the 

 sides Tail unspotted. Female nearly similar. Length, 5.50 ; wing, 3.00 ; tail, 2.35. 



In autumnal specimens the light stripes on the head are deeper buff than in spring. 



Hab. Eastern Province of United States (rather Southern); Southeastern Mexico; Gua- 

 temala; Cuba ; Costa Rica; Teiagua; Orizaba (winter, Sitmichrast) ; Yucatan (Lawrence). 



Habits. Much remain.? to be ascertained in regard to the hi.story, liabits, and 

 distribution of this interesting species. So far as is now known it is hardly 

 anywhere very common during the breeding-seasoh. Yet its abundance and 

 wide distribution as a migrant during the winter months in various extended 

 localities appear to warrant the belief that it must be correspondingly abun- 

 dant in summer in localities that have escaped our attention. It has been oc- 

 casionally met with in the Central and Southern States, as far west as Eastern 

 Mexico, and as far to the north as Southeastern New York. Specimens have 

 been procured from Cuba, Mexico, Central America, and tlie northern portions 

 of South America. It is a regidar winter visitant of Jamaica, wliither it goes 

 in the autumn in considerable numbers, and is very widely diffused. 



It reaches Pennsylvania about tlie middle of ]May, and leaves in Septem- 

 ber. Wilson noticed a pair feeding their young about the 25th of June.
