DiscussioD: A. tenuicornis may be separated from diversella by 

 the relatively uniformly colored forewdng, the presence of scalari- 

 form spines of the manica, and the broad opening of the ductus 

 bursae. Females of tenuicornis approach some specimens of L. vari- 

 abilis in appearance. The lack of a signum will quickly distinguish 

 them from any species of Lita.
