NOTES ON NORTH AMERICAN STRATIO.MYID.E. 



BY A. L. MELANDER, CHICAGO. 



While arranging the flies of this family contained in the Garr}' de N. 

 Hough collection of the University of Chicago, together vvith my own 

 material, a number of notes have been made, which are here given. This 

 family, like a number of other dipterous groups, needs monographic 

 study owing to the confused and scattered descriptions of most of the 

 forms. Of recent years the number of genera has been multiplied, 



January, 1904.
