abnormal — its colours being plain black and white, and its habits 

 rather resembling those of a Tree-Creeper — in other groups chest- 

 nut, bluish-grey and green appear-, the last A^arying from an olive 

 to a saftron tint, and in some groups the yelloAV predominates to an 

 extent that has gained for its wearers, belonging to the genus 

 Dendrceca, the name of " Golden " Warblers. In the genus Seto- 

 jiJaiga, the members of Avhich deserve to be called " Fly-catching " 

 Warblers, the plumage of the males at least presents yellow, orange, 

 scarlet or crimson, and recalls the Redstarts of the Old World. 

 Dr. Coues (Key N. Am. Birds, ed. 2, p. 288), following on the whole 

 the arrangement of Baird, Brewer and Ridgway (i\'^. Am. Birds, i. 

 p. 178), separates the Family (for which he Avrongly retains the 

 name Sylvicolidai) into three subfamilies, Sylvlcolinse ( = Mniotiltinse), 

 Ideriinm and Setopliaginse, grouping the genera Mniotilta, Parula and 



Hp.lminthotherus. 



Dendececa. 



Mniotilta. 

 (After Swainson.) 



Setophaga. 



Feucedrom.us as " Creeping Wai-blers " ; Geothhjpis, Oporornis and 

 Siurus as " Ground - Warblers " ; Brotoiiotaria, Helminthotherus and 

 Helminthophila as " Worm-eating Warblers " ; Setophaga, CardeUina 

 and Myiodiodes as " Fly-catching Warblers "' ; Ideria (Chat, p. 85), 

 which perhaps may not belong to the Family, standing alone ; and 

 Dendroica as " Wood- Warblers. " ^ 



The Mniotiltidx contain forms exhil;)iting quite as many diverse 

 modes of life as do the Sylviidm. Some are exclusively aquatic in 

 their predilections, others affect dry soils, brushwood, forests and 

 so on. Almost all the genera are essentially migratory, but a large 

 proportion of the species of Dendroica, Setophaga and especially 

 Basileuterus, seem never to leave their Neotropical home ; while the 

 genera Leucopeza, Teretristis and Microligia, comprising in all but 5 

 species, are peculiar to the Antilles. The rest are for the most part 

 natives of North America, where a few attain a very high latitude,^ 



^ III 1887 Mr. Ridgway {Man. N. Am. B. pp. 480-532) recognized 20 genera 

 as belonging to the United States, while another comes very near their southern 

 boundary, but he made no attempt to separate subfamilies. 



^ Seven species have been recorded as wandering to Greenland, and one, 

 Dendroeca viren.s, is said to have occurred in Europe {Nauinannia, 1858, p. 425) ; 

 Gatke, Vogelwartc Helgoland, p. 326 ; Eng. trans, p. 315.
