THE CANADIAN ENTOMOLOGIST. 139 



and examined at noo-u, when it was found that two eggs had been deposited, 

 this was within an hour from the time of their exposure. Again it was 

 examined early in the evening, when the number of eggs deposited had 

 increased to nine, and a great many punctures had been made on different 

 parts of the fruit where the curculios had been feeding. 



These experiments I think clearly prove that they work in the dark as well 

 as in the light, feeding and depositing eggs at night as well as in the day- 

 time — that is during the warmer parts of the season, for it should be observed 

 that at the time I operated the nights were quite warm. 



With regard to the best time for jarring, experience leads me to believe 

 that the evening is preferable, provided the work is not undertaken too early, 

 say about sunset, or if it is done in the morning the earlier the better. I 

 will give you a little incident connected with evening jarring. Having just 

 observed a curculio drop on the sheet where I was at work, and having a few 

 minutes to spare I resolved to watch to see how long the creature would 

 feign death. For half an hour a careful scrutiny was kept up, during which, 

 time it did not move a muscle. How long it would have continued in this 

 state is uncertain, as I had no more time to devote to the experiment; just 

 then an attempt was made to pick the curculio up, when, as soon as it was 

 touched, it began to run vigorously. While watching this specimen another 

 was observed on a low outer branch of the same tree which the slight previ- 

 ous jarring had failed to bring down. It remained quite still for a good 

 while on the branch, then walked a few steps, stopping a while again, and so 

 on, during the half hour it did not progress more than two inches in all. 

 An attempt was now made to see if shaking would bring it down on the 

 sheet. Beginning lightly the shaking was increased in rapidity every time 

 until it became quite violent, much more so than any large tree could be 

 shaken, but it maintained its hold on the limb and became more active 

 between the intervals of shaking. Being satisfied that shaking would not 

 do, jarring was tried, when a single tap brought it to the ground.

This butterfly appeared earlier than usual with us this year. It is not 

 seen on the wing sooner than the 10th or 12th of June, but this season they 

 were tolerably common as early as the 1st, and probably had been then flying 

 for several days. They delight in the sunny openings found oftimes in 

 partially cleared woods, also in wooded lanes and roads and the sunny edges 

 of the forest, where by their peculiar jumping flight they may be readily 

 recognized, sometimes singly, at other times sporting in twos and threes.
