(. 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 phoeniceus). 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 ccirolinensis) , 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,
