Descriptions of three new species of the genus Icterus {Briss. ;) specimens of which 

 are in the Museum of the Academy of Natural Sciences of Philadelphia. 



By John Cassin. 



Icterus maculi-alatus, nobis. Capite toto, dorso, alis et cauda, nigris ; 

 hoc colore ad pectus, ut in caeteris hujus generis speciebus, extendente. 



Scapularibus, alarum tectricibus minoribus, et corpore totosubtus a pec- 

 tore ad caudam, flavis ; hoc colore in pectore et scapularibus intensiore. 



Alarum tectricibus majoribus maculis apicalibus, albis, subrotundis, fas- 

 ciam in alam conspicuam facientibus. 



Remigibus primariis, pogonio externo, prope apicem, attenuatis, et ubi 

 coarctantur, extus albo-marginatis. 



Long. tot. exuviae, ab rostri apice usque ad finem caudae 7 poll., alae 

 3.8-10, caudae 3.4-10 poll. 



Hab. Mexico ; prope Vera Cruz. 



Whole head, back, wings and tail black ; this color extending to the 

 breast, as in other species of this genus. 



Shoulders, lesser wing coverts, and entire under parts of the body, from 

 the breast to the tail, yellow, darkest on the breast and shoulders. 



Greater wing coverts with rounded white spots at their tips, forming a 

 conspicuous bar on the wing. 



External webs of primaries attenuated near their tips, and at the point of 

 attenuation edged (externally) with white. 



Total length of skin from tip of bill to end of tail 7J inches, wing 8.8-10, 

 tail 3.4-10 inches. 



Hab. Mexico, near Vera Cruz. 



This species resembles no other which I have met with, and may readily 

 be recognized by its conspicuous and peculiar white bar on the wing, formed 

 by large white spots at the tips of the greater coverts. Upon examination 

 it will be found that these spots are on the outer webs only. 



I have seen one specimen only of this species, which belonged to the 

 Rivoli collection. 



Icterus auricapillus, nobis. Capite supra nitide aureo flavo. 



Persona vittam frontis formante, oculos in totum complectente, ad pectus 

 excurrente, nigra. Dorso, alis et cauda eodem colore. 



Scapularibus, uropygio, caudae tectricibus superioribus, et corpore toto 

 subtus (a pectore) flavis. 



Alis et corporis partibus caeteris prorsus sine albo. 



Long. tot. exuviae, ab rostri apice usque ad finem cauda 7 poll., alae 3.6-10, 

 caudae 3J poll. 



Hab. Mexico et America meridionali. 



Head above bright golden yellow.
