the median vein near the base), I would suggest the 

 adoption of Olethreutinse corrected from Olethreutse, Hb. 

 (Tentamen), the family in which he placed his genus 

 Olethreutes, which dating from 1806, I believe to be the 

 oldest family name adopted for any species now classed 

 with the Grrapholithin&j its type being Olethreutes 

 arcuella. 



Anticipating criticism on the ground of inconsistency, 

 I may add that the manner in which Treitschke ignored 

 Hubner's earlier work will render revision of his generic 

 names absolutely necessary whenever the whole subject 

 of the classification of the Tortricidse and Tineidds comes 

 to be dealt with, but with respectful regard for con- 

 servative prejudices on both sides of the Atlantic, we 

 may leave Semasi<t, Ptedisca, and Penthina, as used 

 in this paper on respite to come up for judgment 

 when called upon. I have almost abandoned the hope 

 that my friend Dr. Kernald will carry out his old in- 

 tention of dealing with this subject in a comprehensive 

 manner.
