144. YELLOW-THROATED VIREO. 
Vireo flavifrons Vieill. 
Summer resident; tolerably common. This beautiful Viero 
is olive-green on the back, and the throat and forebreast is 
bright yellow, changing to white on the belly. It frequents

Flymenoptera, Coleoptera, and larve of Lepidoptera.

Mniotilta varia. (Linn.). 
Summer resident; common. This genial litthe Warbler was 
plentiful in August in the mountain districts, in which it breeds,

specimen secured contained traces of Dipéera.

Protonotaria citrea (Bodd.). 
Summer resident; rare. I took a specimen of this fine 
Warbler August 3 near Buckhannon, in a swampy woods. It
