518 Lord Walsingham on American Tortricidas, 
the median vein near the base), I would suggest the 
adoption of Olethreutinse corrected from Olethreutae, 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 Graph oUthinds, its type being Olethreutes 
arcuella. 
Anticipating criticism on the ground of inconsistency, 
I may add that the manner in which Treitschke ignored 
Hiibner^s earlier work will render revision of his generic 
names absolutely necessary whenever the whole subject 
of the classification of the Tortricidse and Tlneidae comes 
to be dealt with, but with respectful regard for con- 
servative prejudices on both sides of the Atlantic, we 
may leave Semasia, Psedisca, and Penthinaj 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. Keruald will carry out his old in- 
tention of dealing with this subject in a comprehensive 
manner.
