336 NORTH AMERICAN TRYPETINA. 



an Ortalida; the former, however, seems more probable. Its 

 occurrence in America is uncertain, and is only supposed by R. 

 Desvoidy, because the described specimen belonged to Palisot de 

 Beauvois collection. 



12. caliptera Say is synonymous with T. (Eutreta) sparsa Wied. 



13. cinctipes Harris is to be stricken out, as uudescribed. 



14. comma Wied. ; an Eurosta, has been described in this volume. 



15. cornigera Walk., an unimportant variety of the male of T. longipennis 



Wied. 



16. cornifera Walk., same remark as the preceding. 



17. cribrata v. d. Wulp (1. c. p 158), syn. with T. (Eurosta) latifrons Lw. 



18. culta Wied., a Carphotricha, described above. 



19. dinia Walk. In the Monographs, Vol. I, I expressed the supposition 



that it may belong to the relationship of T. (Aciura) tibialis; but 

 in doing it, I paid too little attention to the coloring of the body. 

 I think it more probable now that this is a species closely allied to 

 T. (Hexachceta) eximia Wied., perhaps even only a badly described 

 variety of this very species. 



20. electa Say, a Spilographa ; has been described in Monographs, Vol. I. 



21. eximia Wied., a Hexachceta, described above; known long ago as a 



Brazilian species ; its occurrence in Mexico has been discovered 

 recently. 



22. fasciventris Macq., synonymous with T. (Hexachceta) eximia Wied. 



23. femoralis Thorns., an unknown Urellia from the group with two 



bristles on the scutellum. 



24. fimbriata Macq. is the same as T. (Carphotricha) cidta Wied. 



25. flavonotata Macq., a species closely allied to T. (Spilographa) electa 



Say, but not a mere variety of this species, as I formerly supposed. 

 It is described in this volume. 



26. flexa Wied. is a Tritoxa (Ortalida). 



27. fraterculus Wied., described by Wiedemann as Dacus f rater cuius, 



after a specimen from Brazil ; occurs likewise in Peru, New 

 Granada, and Cuba. Belongs in the genus Acrotoxa, and is the 

 same as Trypeta unicolor Lw., Monographs, Vol. I. Wiedemann's 

 description did not enable me to recognize this identity, which I 

 have, however, found out since, by comparing the original speci- 

 men. As a matter of course, Wiedemann's name has to be main- 

 tained. 



28. fucata Fair, may be referred to Tephritis, and has been described 



above. 



29. ralvifrons Macq. is Chcetopsis oznea Wied. (Ortalidae). 



30. genalis Thorns., from California; unknown to me; probably a 



Tephritis. 



31. inermis R. Desv., published as a Strauzia, is T. (Straussia) longi- 



pennis female.
