{Perisoreus canadensis). It was these specimens from a non- 

 migratory bird of Canadian life-zone that led to a study of this 

 species and the finding of an almost parallel case in the distribu- 

 tion and habits of Ornithomyia anchineuria. Some specimens are 

 slightly darker than others and vary from 2 to 2.5 mm. The 

 wing is shown in figure 1, and the following species in figure 2.

Say's type was taken on the Bluebird, "Sylvia sialis." No 

 locality is mentioned. Wiedemann gives "Pennsylvania," and 

 in Aldrich's Catalogue is "West of the Mo. River." In Smith's 

 Insects of New Jersey, 1899, p. 699, I recorded it from the 

 Bobolink or Reed-bird {Dolichonyx oryzivorus) and Red-winged 

 Blackbird {Agelaius phceniceus). The specimens were collected 

 by Mr. Charles Liebeck along the Delaware River below Phila- 

 delphia, Aug. 19 to Sept. 27, 1892-97. A specimen was taken on 

 a Hermit Thrush (Hylocichla guttata pallasii) at Clifton, Pa., 

 Oct. 19, 1897, by Mr. C. A. Voelker. A specimen was also ob- 

 tained from a Robin (Planesticus migratorius) at Southbridge, 

 Mass., Aug. 18, 1914, by Mr. S. W. Bromley, and from a young 

 Junco {Junco hyemalis) at Woodstock, Vt., Aug. 1911, by Mr. 

 A. P. Morse. In the Museum of Comparative Zoology is a 

 specimen from the Red Crossbill (Loxia curvirostra minor) 

 collected at North Bay, Onatrio, Sept. 7, 1896, by G. S. Miller, 

 Jr., and from the Catbird (Dumetella carolinensis) , at Worthing- 

 ton, Mass. Another specimen in the same Museum was collected 

 by Mr. W. S. Brooks at Ellis Bay, Anticosti Island, Sept. 3, 1919. 

 from a new Jay (Perisoreus barbouri) allied to the Canada Jay,
