The beetles continued to oviposit freely until August 10. By this 
time peaches were scarce and no further observations were made 
until August 17, the beetles being fed on foliage alone during the 
intervening week. On August 17 some late seedling peaches, both 
green and ripe, were put in the jars and on the next day were exam- 
ined for eggs, only two being found. Xo more eggs could be obtained 
from these beetles or from beetles recently captured by jarring, 
although eggs were being laid in the field, where fruit was available, 
for a month longer. 
All eggs laid by the new-generation beetles appeared to be fertile 
and hatched in from three and one-half to four and one-half days 
unless injured by handling. One hundred and eighty-live individuals 
were reared through to the adult state under the same outdoor 
conditions used in the other rearings. The larva? developed in ripe 
peaches, remaining in the fruit from 9 to 24 days. The life in the 
soil ranged from 18 to 45 days and the entire life cycle from 36 to 
61 days. The adults from this material emerged from the soil August 
22 to October 10. Adults from infested peaches collected in the field 
emerged as late as November 9, at which date there were yet many 
pupa? and even larvae in the soil, though there is no evidence that 
these late individuals from the field were of the second generation. 
BEETLES FROM EMERGENCE TO HIBERNATION. 
In general, after emergence the adult insects pass the time in 
hiding and feeding, their activities growing le<s and Less at the 
approach of cold weather, until finally they seek hibernation quarters 
for the winter, which, as shown, may be in orchards under trash, etc., 
on the ground, but especially in neighboring wood--. 
More detailed information is needed upon the habits of the beetles 
after emergence, especially in the South and in other regions where 
the fruit crops are practically all gathered by midsummer or earlier. 
Under such conditions the weevils arc at once largely deprived of 
fruit for food and doubtless subsist on foliage, buds. etc. In regions.
