Making a total of eleven sweepings and 268 specimens. It 
should be noted that this is the date on which the first nymph was 
found in the alfalfa. It was very small, being in the first stage. 
As the field of alfalfa on which we had made the previous sweeping 
had been cut down, we had to sweep another somewhat smaller 
field. The sweeping and counting on this field was done in the 
same way as in the other field, and the results were as follows, the 
field being about the same width as the one above, June 25th:

Making a total of five sweepings and 275 specimens. This field 
was somewhat farther away from any apple trees than was the 
first one. A few nymphs in the first stage were found. If the 
results of the sweepings made on these different dates be examined 
and compared carefully, it will be seen that the individuals taken 
increased steadily in numbers from the first to the last, with the 
exception that the sweeping on the 14th of June gave a somewhat 
smaller number of adults than did that on the 11th. This falling 
off on the 14th of June, however, is readily accounted for by the
