Family LANIIDiE. 

 Genus Collurio Vigors. 



79. C. borealis Bd. Gukat Northern Shrike. Regular Aviutcr 

 resident. Arrives the last of October and generally departs the last 

 of March. Sometimes they I'cmain late in tlie season and may breed. 



80. C. ludovieianus var. ludovieiamis Linn. Loogkiuikad 

 Sni;iKK. Common summer resident throughout the state. I Jiave ob- 

 tained its nest ■with a full set of eggs early in April, near Chicago. It 

 generally arrives about the middle of March. 



A small series of shrikes from the northern and southern extremes 

 of the state have been submitted to my friend, Mr. J. A. Allen, who 

 replies as follows: "They all belong decidedly to var. ludovieianus, 

 though somewhat lighter tlian Florida specimens, with smaller bills, 

 etc. There is a slight approach in some of them to cxcubitoroides, 

 but the resemblance to Florida specimens is far greater than to spec- 

 imens from the West — Wyoming, Utah, Colorado, etc." During the 

 past two years I have examined a large number of shrikes from north- 

 ern Illinois, and have found them, in nearly all cases, to be much 

 nearer Indoviciamis than cxcubitoroides. Specimens obtained in the 

 Wabash Valley and other parts of Southern Illinois, exhibit the same 

 characteristics in about equal proportion, as far as the number of 

 specimens seen would permit me to judge. 



80«. Var. excubitcroides also occurs throughout the state, 

 especially upon the prairies, but is much less numerous than the east- 

 ern form. Their habits are identical. 



Family TANAGRID^. 

 Genus Pyranga. 



81. P. rubra Vieill. Scarlet Tanaghr. Common summer resi- 

 dent. Arrives May 8th and leaves early in autumn. 



82. P. sestiva Vidll. Summer Kkd-bird. A rare summer visit- 

 ant. 1 know of but few instances of its occurrence. 



Family FRINGILLIDiE. 

 Genus Hesperiphona Bonap. 



83. H. vespertina Bonap. Evening Gi;osbeaiv. A winter vis- 

 itant occurring at irregular intervals. The Avinter of 1871 they were 

 quite common throughout tlie northern portion of the state. The 

 following winter they were much rarer, and since then but very few 

 have been seen. I am told that formerly, it was of much more reg- 

 ular occurrence.
