A'ote. — It appears from the article just mentioned that this European 

 species was first observed in New Jersey and Maryland, on cattle, in the 

 summer and fall of 1887, although the first reference in print was by 

 Lintner, supra, in 1888. Williston saw it from Pennsylvania in 1887 also. 

 The subsequent spread of the fly was traced by frequent references in 

 Insect Life, in the second and following volumes ; the references may be 

 found in the general index of the periodical. Other references which I 

 have collected are mostly to brief notes; the principal ones I list.
