DESCRIPTION OF A NEW FLY OF THE FAMILY DOLI- 

 CHOPODIDAE, WITH REMARKS AND CORRECTIONS 

 OF PRECEDING PAPERS. 



By E. S. Tucker, Bureau of Entomology, U. S. Department of Agriculture. 



T^HE fly to be described herein was collected on one of ray va. 

 -*- cation trips, which altogether have resulted in the collection of 

 numerous species of insects, including several new to science. The 

 names and records, which in great part are additions to the faunal 

 lists of both Kansas and Colorado, wherein the insects were taken, 

 have been published so far as the systematic determinations have 

 permitted. My recent contributions to the lists appeared in volume 

 XXII of the Transactions of the Kansas Academy of Science, under 

 three titles: "Additional Results of Collecting Insects in Kansas 

 and Colorado," pp. 276-304; "Supplementary Additions to the List 

 of Kansas Diptera," pp. 306-307; and "Supplementary Additions 

 to the List of Kansas Hymenoptera," pp. 308-310. Owing to the 

 fact that printer's proof was not submitted to me, a number of 

 errors occur, which require the following corrections: 



Page 278. —Families "SarcophagidsetoAgromyzidse," inclusive, are mis- 

 placed; they belong to end of list of Diptera, on page 307. 



Page 279. — In heading of first specific division, read "agilis" for 

 "agillis"; in sections (1) and (6), read "cinereous" for "cinerous"; also, 

 in (2) and (5), read " ferrugineous, " as spelled in original descriptions, for 

 "ferruginous." 



Page 280. —In part 1 of table, third line, read ' ' cinereous ' ' for ' ' cinerous. ' ' 

 Page 282. —In family Panurgidas, read "Perdita" for "Purdita." 

 Page 286. -Forty-first line, substitute "its" for "other." 

 Page 287. — Fourteenth line, read ' 'ornamentations ' * for ' 'ornamentation. ' ' 

 Page 291.— Thirty-fifth line, read "Vr. " as authority for "Br." 

 Page 295. —Tenth line, read "melUtor" for "millitor." 

 Page 300. —In family Syrphidae, after record for Melanostoma mellinum, 

 add "New to the Kansas list." 



Page 302. — Thirteenth line, read "laterally" for " latterally." 

 Page 303. —Sixteenth line, read "Pelina" for " Pilina." 

 Page 307. — Note continuation of list misplaced on page 278. 

 Page 309. —In second column, with Pristonierus, add appalachianus Vr. , 

 to indicate typical form. 



With reference to the validity of three closely allied species of 

 bees, as discussed on pages 278-281, Prof. T. D. A. Cockerell hue 

 written me as follows: ""Melissodes agiiis and M. aurigenia I have 

 regarded as forms (races) of one species. They may be distinct.
