The occurrence of this species west of the plains seerns to be accidental, 

 since I do not find it recorded from any point west of Kansas, to the fauna 

 of which State it has recently been added by Mr. Frank H. Snow. I took 

 a fine male in adult plumage near Denver, May 17, 1873. This was 

 migrating in company with a flock of Audubon's Warblers; no others 

 were seen. 



DENDROICA CAERULEA (Wils.).

A small warbler seen May 17 was unquestionably of this species. Its 

 small size and bright blue color made it conspicuous among a flock of Audu- 

 bon's Warblers as they passed rapidly from tree to tree, but, my attention 

 being diverted for a moment, I lost sight of it, nor was it again seen. Not 

 hitherto detected west of the plains. "Apparently common at Leavenworth, 

 Kansas" (Allen).
