LIST OF DIPTERA. 



Attention is called to the tabulated summary which appears at 

 the end of this list and gives a comparative disposal of the number 

 of species with reference to families. The names of thirty-six 

 species are reported as new to the Kansas lists. This number 

 includes ten new species in the following families : Chironomidse, 

 five named and described by O. A. Johannsen (not counting a 

 change of name) ; Cecidomyiidse, three by E. P. Felt ( MS. names) ; 

 Asilidae, one by J. S. Hine; and Helomyzidae, one by myself (de- 

 scription herewith incorporated). From the Colorado material, 

 one new species in the family Trypetidse has been described by E. 

 T. Cresson, jr., and two new species in the family Oscinidse are 

 based upon my own descriptions. 



Through the courtesy of Dr. L. O. Howard, chief of the Bureau 

 of Entomology, United States Department of Agriculture, Wash- 

 ington, D, C. r have been afforded the very helpful services of 

 Mr. D. W. Coquillett in the identification of several species. Mr, 

 E. T. Cresson, jr., has also helped me through difficulties attending 

 the determination of species in the families Muscidse, Borboridse, 

 Ortalidae, Trypetidse, and Ephydridse. Other acknowledgments of 

 assistance are made in the proper places. 



The plan of systematic arrangement herein employed is the same 

 as was used in my previous paper treating of the Diptera.
