[HI] IDENTITY OF HYPENID^E. 223 



As the description of Tortricodes bifidalis precedes that 

 of H. indimsalis, the latter must give way as a synonym. 



In some of its features this species does not conform to the 

 definition of the genus to which it has been referred. It will 

 probably, need a new genus for its reception. 



That a single species has at the same time been given place 

 in two genera, 'should not in the least degree reflect upon Mr. 

 Grote. The author of the erroneous information conveyed to 

 him, as above quoted, is alone responsible for the mistake. 

 That two forms, so very unlike in construction of wing, should 

 have been believed, at the first, to be identical, gives assurance 

 that the difficult task of identification of species often imper- 

 fectly described, description of new forms, and systemiza- 

 tion of the North American Heterocera, has been undertaken 

 by one peculiarly fitted for the work.
