nomic points are summarized as follows: ‘‘ (1) The variety of plum or 
apple whose blooming season covers the greatest period of time will 
best withstand the work of the curculio; (2) the planting of plum 
trees in the apple orchard will not protect the latter, and vice versa ; 
(3) if anything is to be gained by using another fruit to draw off the 
curculio and protect the plum, the nectarine will probably serve as well 
as the apple ; (4) adult curculio beetles eat the pulp of apples ; (5) cur- 
culios will deposit their eggs in fruit hanging over the water ; (6) the 
indications are that the Strawberry Crown Borer lays its eggs during 
March and April in the plants near the surface of the ground ; (7) 
burning strawberry"plants after fruit-picking may destroy the Crown 
Borer ; (8) the common field cricket will eat strawberries.’’ 
Oviposition of the Apple Curculio.—Mr. C. P. Gillette has 
lately described the process by which the eggs of Anthonomus quadrigib- 
are deposited. The description was originally read before the lowa 
Academy of Science, September, 1890, and has since been published 
in Bulletin No. 11 of the Iowa Experiment Station (pp. 492-493)- 
Mr, Gillette says : «I am not aware that any one has published actual

observations on the method of oviposition of this insect. On the 
13th of last June I was fortunate enough to see a female perform the 
entire operation, which was done as follows: First, a cavity (Fig. 1, 5) 
was eaten in the apple as deep as the beak was long, the bottom being 
much enlarged and subtriangular in outline. The walls of the cavity 
converge to the opening, which is only large enough to admit the slen- 
der beak. When first noticed the beetle had begun her work and it 
was 30 minutes before the egg-cavity was completed. The beetle, r 
most immediately after withdrawing her beak, turned about an 
applied the tip of her abdomen to the small opening into the egg-

cavity. After remaining in this position for about five minu 
S work she had done.
