in some of the immense spruces or hemlocks of this region. Fe- 

 males were taken the second week in June that bore marks of incu- 

 bating, yet we were unable to find its nest. This species winters in 

 the West Indies, and a few remain at Key West, where they are 

 abundant during the migrations. I think it must reach its winter 

 quarters by way of the Great Lakes and Mississippi Valley, as it 

 does not occur in any numbers in Massachusetts. 



36. Myiodioetes pusillus Bon. Black-capped Fly-catching 

 Warbler. 



Not common at Norway (Verrill) and Gorham (Brewster) during 

 summer. Bare at Hamilton (McBwraith). Not given at Quebec 

 (Couper). We did not see it at Umbagog in June. Not found at 

 Franconia (Brewster). 



37. Myiodioetes Canadensis Aud. Canada Fly-catching 

 Warbler. 



Common at Umbagog, also at Quebec (Couper), and at Norway 

 (Verrill). Not rare at Hamilton (Mcllwraith) . It breeds at all these 

 places. Nests at Umbagog about the second week in June. It 

 probably winters in Mexico and Central America. 



38. Setophaga ruticilla Sw. Bedstart. 



Common at Upton, Quebec (Couper), Hamilton (McBwraith) and 

 at Norway (Verrill). Breeds in all these localities. Winters in the 

 West Indies. Passes through Florida on its way north in April. 



HIRUNDINIDiE. 



39. Hirundo horreorum Bart. Barn Swallow. 

 Abundant at Umbagog. 



40. Petrochelidon lunifrons Bd. Cliff Swallow. 

 Common everywhere. Breeds; nesting at Umbagog about the 



middle of June. 



41. Tachyeineta bicolor Cab. White-bellied Swallow. 



Common everywhere. Breeds at Umbagog, nesting in old decay- 

 ing stubs that have their bases submerged in the lake,. It either ex- 

 cavates a hole for itself, or selects one formerly used by a wood- 

 pecker. I have seen two holes in one stub. Lays its eggs the 

 second week in June. 



42. Cotyle riparia Boie. Bank Swallow. 

 Common everywhere.
