Busck — Notes on Some Tortricid Genera 175 



Lederer's genus his first species, hvxfiiionana, both genera may 

 be retained and a more natural division of the group result. 



In Ilemimene would then be placed the American species 

 hitherto described and the following European species : plum- 

 hana, simpliciana, saturnana, ligulana, plamhagana, agilana, 

 incursana, petiverella, sequaiui, alpestrana, alpinana and proba- 

 bly most of the other species, at present included in both genera 

 except hugnionana and harpeana, which together with two 

 American species described in this paper, would make up the 

 genus Lipopti/rhn.* 



Thus arranged the two genera may be separated by the fol- 

 lowing characters:

 median vein as broad or broader median vein narrower than the

 ing beyond anal angle of fore wings. beyond anal angle of fore wings. 



* Second joint of labial palpi yel- ^ Second joint of labial palpi not 

 low at base. yellow. 



The last color difference I certainly do not intend to advocate 

 as a generic character of general value, but it holds good in all the 

 species of the groups under consideration, with which I am ac- 

 quainted, and I include it as another small but rather significant 

 circumstantial evidence of the propriety of the rearrangement of 

 the species. 



All of the above characters may seem trivial, but it should be 

 considered, that the Tortricidae is a remarkably uniform and 

 conservative family, embracing closely allied genera; nearly all 

 characters usually available and important are more or less 

 identically developed in the entire family and any small, con- 

 stant differences found must therefore be depended upon and 



* Some of these are unknown to me except from descriptions and I should not be 

 surprised if some of the other Alpine species shall be found to fall with harpeana and 

 bugnionana.
