abnndant on alfalfa by March 28. a 
^Thile all of these data may at fii sf seem of little consequence, they 
bear directly, as ill appear later, on what now seems to be the 
planter's only hope of eliminating the ravages of the pest in his 
cornfields. It is fair to suppose that these females deposit eggs in 
the fields as soon as there is food for the larvae, and it is the larva 3 
from these eggs that become so destructive in the fields of young 
corn, especially in the South. T::c reason they are not equally in- 
jurious in the North may perhaps be that by the time oviposition 
begins in spring and the larva? have hatched com has bee me : 
advanced in growth to enable these young larva? to penetrate the 
stem the usual point of attack. 
Mr. Vickery. who followed the species through the season at Salis- 
bury. X. C-. in 1 . settled the question of the number of generations 
that occur annually at that point, finding that thei two. All of 
the observations of the author and these of several of the men work- 
ing under his direction have shown that this is generally true 
throughout the country where the adult hibernates, but may not 
apply in the far South, where hibernation does not take place. 
Prof. Quaintance. at Experiment, in central Georgia, noted the first 
appearance of the larvae attacking corn on May 2. The first pupa 
was found May B. and the first adult, evidently of the nevr _ :ion.

Mr. C. L. F sterwi : as I Hows from. Dalton, in northern Georgia, 
on July 30, 1910: 
I am mailing yon a sample of worm tliat is causing: great damage to the 
corn crop of our country- When the corn plant is small these worms bore into 
the center of the stalk underneath the soil and Mil the plant by destroying the 
"bud." When the plants are larger they bore into some of the larger roots, 
but more generally into the stalks among the roots, which does not kill the 
plant outright, but injures it so that it rarely produces corn to amount to 
anything. The plat where these were found has been planted three times this 
season, and there are very few stalks now on the plat but what have been 
injured by the worms. The worms were not so plentiful on July _ - They 
were on July 6, when the samples first sent you were collected. 
From the foregoing letter it would appear that the second _ 
tion of larva? were at work in late June and July in northern Georgi 
Air. George G. Ainslie studied the larva?, at that time 3 to 6 milli- 
meters in length, at Hurricane. Tenn.. May 27.1 B0 3 1912. T 
must have been full grown by the latter date, as none could be found 
in the fields Jv: :d a recently emerged adult was taken on 
June 14. 
The author observed full-grown Lr eking late-planted
