334 NORTH AMERICAN TRYPETINA. 



must be united generically with the subgenus Tephritis, or else 

 that it should be separated from it in some other manner than 

 has been hitherto done ; and that, in order to facilitate the iden- 

 tification of species, a new genus, closely allied to the two above 

 named ones, should be founded, for which I have already pro- 

 posed the name of Euaresla. 



I reserve for another place to carry out in detail the improve- 

 ments of the system of Trypetina of which I have here given 

 the outline, and I intend, at the same time, to take in considera- 

 tion the known species from all the other continents.
