Order DIPTERA 

 Edited by O. A. Johannsen 



The original draft of the list of Diptera was completed more than twelve 

 years ago. It was based in large part on the specimens in the Cornell 

 University collection and in the State Museum at Albany, and on pub- 

 lished records. When Dr. M. D. Leonard assumed the editorship of the 

 list of the insects of New York, and the prospect for publication became 

 brighter, the parts relating to some of the families were sent to specialists 

 and later the entire list of Diptera was submitted to C. W. Johnson and 

 Dr. Joseph Bequaert, Many additional records were thus obtained. 

 Acknowledgment to the various entomologists who have helped to make the 

 list more complete, is made in the appropriate places. 



The classification followed, in the main, is that given in Comstock's 

 Introduction to Entomology. The arrangement of families and genera, 

 with slight modifications, is that of Johnson's List of the Diptera of New 

 England. Bibliographical references are not made, owing to the Hmita- 

 tions of space. The reader is referred to Aldrich's catalog of the Diptera 

 for those prior to 1905, and to Johnson's list for the more important 

 recent ones. Synonymy is given only in a few cases, where otherwise a 

 misunderstanding might arise.
