258 Report OF THE ENTOMOLOGISTS OF THE 
stating that the larve of the striped cucumber beetle require moist 
earth to live in and that they feed upon the vines and fruit of the 
squash, melon and cucumber wherever the latter come in contact 
with the moist earth. Possibly they feed upon the roots proper, 
but we have no direct proof of this. 
Pupa.— Mr. Chittenden has proven that the pupal or resting 
stage can be passed in seven days. A number of writers have 
stated that the pupal stage lasts two weeks. The larva forms an 
earthen cell in which it changes to a pupa, but does not form a 
cocoon as stated by some. 
Hibernation.—According to Dr. Shimer* and Mr. Saunders? 
the striped cucumber beetle passes the winter in the pupal state. 
This is a mistake, as more recent investigations show that they 
pass the winter as adult beetles as does the potato beetle. Like 
the latter they go below the frost line to hibernate. 
Number of broods.— Most of the writers to whose work I have 
access, state that there are several broods of the beetles each year. 
It is true that the beetles occur in large numbers in the spring and 
again in the fall, and if the statement that they hibernate as pup 
is correct, then the statement that there are at least two broods 
each year would be correct also. My field notes show that the 
beetles begin to decrease in numbers toward the end of July, but 
do not all disappear until September, and sometimes not until the 
new brood of beetles appears. Thus beetles can be found 
throughout the entire summer and fall. In fact, during July, 
August and September of 1898 I was able to collect beetles every 
week. ‘The dissections indicate that the beetles collected during 
August and the first half of September were mostly males and 
diseased or imperfect females. The dissections of the females of 
the new brood show also that the reproductive organs are not 
developed and do not develop even as late as the middle of October. 
Furthermore, by the dissections it was shown that a large amount 
of fatty tissue is formed preparatory to hibernation. It addition
