This little bird visits Illinois only at the apprcicb of cold 

 weather, and leaves with the advent of spring. He frequents chiefly 

 the woods, more especially in bottom lands, where he may be seen 

 about old logs, hopping nimbly in and out among the knot-holes and 

 other hollow places, then flitting, like a brown butterfly, to another 

 place of refuge on the too near approach of an intruder. Occasion- 

 ally he may be seen about wood-piles or lumber-yards within towns, 

 but he is never on the same degree of intimacy with man as the 

 House Wren, partaking, in his sylvan proclivities, more of the 

 nature of his larger and brighter-colored relative, the Carolina 

 Wren. 



Gends CISTOTHORTIS Cabanis. 



Cistothorus Cabanis, Mus. Heiu. 1, 1850, 77. Type. Troglodt/tes slellai is Light. 



Telmatndytes Cabanis. Mus. Hein. i, 1850, 78. Type. Tliryotliorus arundinaceus 

 YiEtLij., =Certhia palustris WtLs.) 



"Gen. t'HAE. Bill about as long as the head or much shorter, much compressed, not 

 notched, gently decurved from the middle: the gonys slightly concave or straight. Toes 

 reaching to the i nd of the tail. Tarsus longer than the middle toe. Hind toe longer than 

 the lateral, shorter than the middle. Lateral toes about equal. Hind toe longer than or 

 equal to its digit. Wings rather longer than the tail, all the feathers of which are much 

 graduated; the lateral only two thirds the middle. The feathers narrow. Back black, 

 conspicuously streaked with white. 



"Of this genus there are two sections, Cistothorus proper and Tel- 

 matodytcs, the diagnoses of which have already been given. The 

 two North American species present the feature, unique among our 

 Wrens, of white streaks on the back.
