Remarks. — The distinguishing characters of this and querdcella 

 have been discussed under the latter. 



Although ohsoletella and quercicella cover much of the same range, 

 the former appears to be the more widely distributed of the two. 

 Much more rearing must be done to establish the limits of both.
