84 KANSAS UNIVERSITY SCIENCE BULLETIN. 



F. H. Snow ia the Kansas University Science Bulletin, vol- 

 ume TI, No. 5, to which additions were made by Mr. F. F. 

 CreveccBur in Transactions of the Kansas Academy of Sci- 

 ence, volume XX, pages 90-96. In answer to my inquiry, 

 •directed to Prof. T. D. A. Cockerell, whether any list had 

 been attempted for Colorado, I received the reply here quoted : 

 ^' No list of the Diptera of Colorado has appeared I have a 

 manuscript list, as complete as I have been able to make it, 

 of the Diptera of the Rocky Mountains ( principally Colorado 

 and New Mexico), and so can state if any particular species 

 appears to be new to the region." Mr. W. A. Snow pub- 

 lished a paper entitled "Diptera of Colorado and New Mex- 

 ico," in Kansas University Quarterly, volume III, but in 

 this, as well as in a preceding paper, "Notes and Descriptions 

 of Syrphidse " {loc. c t., vol. I), his references are confined 

 to that one family, the Syrphidae, and only so far as he had 

 studied the species then represented in the University col- 

 ilections. Thus the names of those species which I have re- 

 corded as being found in Colorado should be of material help 

 towards forming a preliminary list for that state. 



The finding of new species has been quite gratifying, con- 

 sidering the circumstances and extent of collecting, eleven in 

 all being so far described, in the following families : Myceto- 

 philidge, three by Adams ; Stratiomyidse, two by Adams ; 

 Borabyliidse, one by Williston ; Dolichopodidee, two by Al- 

 drich ; Phoridse, one by Brues ; Syrphidse, one by Snow ; and 

 Borboridse, one by Adams. All these are designated in the 

 list by the term "type" following the name of each one. 

 Eight species and three varieties are herewith described by 

 me as new, three species and one variety being in the family 

 Bombyliidse, three species and two varieties in the family 

 Asilidse, and two species in the family Borboridse.
