TRYPETID^. 



Loew, Mon. N. A. Dipt., iii, 327, 1873, table of genera. 

 Coquillett, Jour. N. Y. Ent. Soc, vii, 267, 1899, table of genera. 



Note. — The order followed is essentially that of the table in Williston's 

 Manual, although Coquillett has pointed out some seeming defects in the rela- 

 tion of genera therein. The genera of this family are closely interwoven, and 

 mostly based on plastic characters ; hence a slight difference in the emphasis 

 placed on one set of characters has the effect of throwing a large number of 

 species into other genera than they previously occupied. This change of 

 emphasis Mr. Coquillett seems to have adopted, as compared with Loew, who 

 established most of the genera; but as he has not published anything to justify 

 his new generic references in most cases, I have been slow to accept them. The 

 synonymy of species by Mr. Coquillett in Jour. N. Y. Ent. Soc, vii, 259-268, 

 seems to me to do a great injustice to Mr. Doane, whose species were very care- 

 fully and accurately worked out. From an examination of Doane's material, I 

 am satisfied that Coquillett was wrong in all, or nearly all, of the assertions he 

 made regarding the synonymy of Doane's species; this was shown in a rejoinder 

 published by Doane, op. cit., viii, 47.
