The above records have a very vital bearing on remedial 

 measures. From June 1 to 11 from 15 to 47 eggs were gener- 

 ally deposited every other day. The 12th being Sunday the 

 beetles were not attended, but two or more clusters being found 

 with each on the following morning, probably one or more were 

 deposited on Sunday. 



The records show that from June 12 or 13 to 23 there was a 

 marked increase in the number of eggs, eight to over 40 being as 

 a rule deposited daily. The record of the beetle confined in the 

 vial indicates a discrepancy greater than the facts warrant. It 

 was impossible to attend the insects on the 18th, so it appears 

 as though two days had been skipped by one beetle and one daj^ 

 by the other, whereas it is probable that there was but a day 

 that the beetle in the vial did not deposit eggs, and the record 

 of the other was probably unbroken, eggs being deposited daily. 



During this short period of 10 or 11 days — June 12 or 13 to- 

 23 — there were deposited over half the total number of eggs 

 produced during the 28 days the record was kept, the figures 

 being 330 and 338 respectively or an average of over 21 and 30- 

 eggs a day. The average number deposited during the first 11 

 days of the month are 14 and 18 respectivel}', which shows that 

 there was an increase in the daily average of one half or more 

 in the case of each beetle after June 11. Those deposited after 

 the 25th were apparently the last efforts of the insects to pro- 

 vide for the perpetuity of their kind, though the quality of the 

 eggs had not deteriorated so far as observable. 



The continued oviposition and the prolificacy of the beetles 

 is strikingly shown in this record. They were abroad in num- 

 bers by May 12, 1808, and oviposition began about the 25th, so 

 the record of these two individuals is probably lower than the 

 normal as they may have deposited several clusters of eggs 

 before being captured. They were both supplied with fresh 

 leaves from day to day and the eggs removed and counted as 

 soon as detected. The female producing the smaller number of 

 eggs was confined in a small, corked vial, while the other en- 

 joyed the freedom of a jelly tumbler. The difference in condi-
