LIFE HISTORY AND HABITS : THE EGG. 
41 
Table V gives by weeks the number of eggs deposited by 8 female 
curculios, as observed by Mr. Fred Johnson, at Youngstown, N. Y., 
in 1905. The beetles were taken while mating, June 6, and each 
pair separately confined in a jelly glass. Observations were made 
morning and evening, at which times also fresh food was supplied. 
At date of capture, June 6, no egg punctures were in evidence on 
fruit in orchards, and the records are doubtless complete.

In Table VI are given records of observations by Mr. Johnson 
in 1906 at North East, Pa. Beetles were obtained by jarring, and 
the pairs in copula placed in individual jelly glasses on May 22. The 
food was Japan plums.
