NOTES ON TRYPETIDiE WITH DESCRIPTIONS 

 OF NEW SPECIES. 



BV R. W. DOANE. 



Since the publication of Loew's Monograph of the Trypetid?e of 

 North America in 1873 several new species have been described by 

 various authors. For the reception of some of these species new 

 genera have been erected. Others very obviously belong to- some of 

 the already established genera, but in order to include these new forms 

 the definitions of these genera have needed more or less modification. 

 Thus we find in this group, as in every other, that no matter how care- 

 fully they may be worked up at any time, in the course of a few years 

 a revision of the work becomes very desirable. Until such a revision 

 shall be made the true location of some of the forms already described 

 and several of those described herewith cannot be definitely deter- 

 mined. In describing the new species that have come before me in 

 the past year I have erected no new genera, choosing rather to place 

 them in genera already established, and to which they seem more or 

 less closely related, leaving the determination of their true location 

 until the time when the family shall be revised. 



In an article on "A New Trypetid " in Ento. News, Vol. IX, 

 No. 3, I set forth my reasons for believing that the segment usually 

 referred to as the ovipositor in this family is really the last abdominal 

 segment, and in drawing up the description of J?. 7-ibicola referred to 

 it as such. Further study of the group gives additional evidence in 

 support of this view, but in order to avoid confusion I have in the fol- 

 lowing descriptions followed the usual custom and referred to this 

 segment as the ovipositor. 



I have to thank Professor J. M. Aldrich, of the University of 

 Idaho ; Mr. Trevor Kincaid, of the University of Washington, and
