APPENDIX I. 337 



32. interrupta Macq., described as Urophora, is not a Trypetida at all, 



but a Rivellia of difficult identification. 



33. latipennis Macq., published as a Piutystuma, is most certainly a 



Trypetida, in which I cannot recognize anything else but T. 

 (Eutreta) sparsa. 



34. Lichtensteinii Wied., described above after the types of Wiede- 



mann's work, and provisionally placed in the genus Icterica, from 

 the typical species of which, however, it is somewhat dilTerent. 



35. liogaster Thorns, is the same as T. (Acidia) frutria Lw. 



36. longipennis [Vied, is the typical species of the genus Straussia, and, 



as it seems, undergoes considerable variations. In Monographs, 

 Vol. I, I have given a description of this species, and in the present 

 volume have enumerated the varieties which I have had occasion 

 to see, some of which, however, may be distinct species. 



37. marginepunctata Macq., almost certainly a Trypetida, but which it 



would be premature to identify with T. (Carphotricha) culta Wied. 

 Macquart's data are so very insufficient that the identification will 

 be very difficult. 



38. melliginis Fitch is a Rivellia, under which head it has been discussed. 



39. mevarna Walk., au Urellia, unknown to me. 



4d. mexicana Wied. , an Euaresta; the above description has been pre- 

 pared from Wiedemann's typical specimen. 



41. narytia Walk. ; the remarks appended above to avala Walk, may be 



repeated here. 



42. novaeboracensis Fitch is synonymous with T. (Eutreta) sparsa 



Wied. 



43. nigriventris Macq., erroneously described as Urophora; it is a Try- 



petida, which I do not know, and concerning the systematic posi- 

 tion of which I am in doubt. 



44. obliqua Macq. is an Acrotoxa ; I do not know it. 



45. obliqua Say is the type of the subgenus Plagiotoma ; is described in 



Monographs, Vol. I. 

 4li. ocresia Walk, belongs to the subgenus Acrotoxa ; I am unable to 

 identify it among the species known to me. 



47. picciola Bigot (R. de la Sagra, Hist. fis. Cub. Tab. XX, f. 10). This 



species, described as Acinia, is the same as T. (Enema) humilis Lw. 



48. picta Fabr., type of the genus Canytoneura (Ortalida). 



49. pomonella Walsh, subgenus Rhagoletis, is described in this volume. 



50. quadrifasciata Macq. I suppose that this species will be found to 



be identical with T. (Permiyma) sarcinata Lw. 



51. quadrivittata Macq. is an Ortalida. 



52. scutellaris Wied. is an Ortalida. 



53. scutellata Wied. is a Trypeta the position of which cannot be made 



out of Wiedemann's description; Wiedemann's typical specimen 

 unfortunately is no more in existence. 



54. septenaria Harris is to be stricken out, as undescribed.
