I have also received examples of this louse from Mr. J. T. Monell 

 that were labeled ''^Manhattan, Kansas, 8-27- '08, Ainsley; taken on 

 red clover"; and specimens from Mr. J. J. Davis marked "Urbana, 

 Illinois, 3-ll-'08; on clover, in insectary." 



From our records and observations there seems to be no doubt but 

 what this louse spends the winter chietly in the egg stage upon apple.
