H. CHRYSOPTERA I GOLDEN-WINGED WARBLER. 115 



The above paragraphs present the original de- 

 scriber's account of the bird, together with a condensed 

 statement of its entire history to date, and including 

 the references to the published account of every speci- 

 men known thus far. It will be seen that the curious 

 bird was discovered in Massachusetts, and that a ma- 

 jority of the specimens are from New England. Only 

 one, discovered in Michigan, being that named H. 

 gunnii, has been taken at any considerable distance 

 from our boundary. The actual range of the species 

 is probably coincident with that of H. ckrysoptera, its 

 nearest ally. As to New England, we can only say, 

 as yet, that the bird is a spring and fall migrant in 

 Massachusetts and Connecticut, probably breeding 

 there. It will be observed that all the known speci- 

 mens are males ; the female, with the nest and eggs, 

 (if, indeed, there be any such things,) remain to be 

 discovered.
