dently preferred these grass roots to the young corn ; for on examining 
a multitude of the hills of corn in which one or more of the young 
plants had been cut off, it was invariably the striped worm first men¬ 
tioned which was discovered there, not one of these Yellow-headed 
worms had as yet molested the corn.' Five days afterwards, this same 
corn field was again visited. The weather in the interval had been 
warm and dry, whereby the grass roots in the clumps of turf had be¬ 
come dry and withered, unadapted for feeding the worms any longer, 
and now on examining where the blades of young corn had been 
newly cut off, the mischief was discovered to have been done in near¬ 
ly half the instances by this Yellow-headed worm, which was found 
lying in the earth contiguous to the severed plant.” 
The date of this visit was June 25. He afterwards states that a few 
years before he found the same Cut-worm making severe havoc in a 
corn field the first of June. In speaking of the habits of the two 
worms still further, he said it could be told which of the two had cut 
off a spear of corn before unearthing it, for the striped worm cut off 
the spear about an inch above the surface of the ground, while the 
vellow-headed worm cut off the spear about an inch below the surface. 
Those cut off by the first would, the most of them, grew again, as 
only the leaves would be severed ; but where the spears were cut be- 
ow the surface of the ground the culms in most cases would be severed 
and those plants would be destroyed. For this reason the vellow- 
headed worm would be the more' destructive of the two to cornfields. 
These worms continue their work of destruction till about the first 
week in July, when they descend into the ground to undergo their 
transformations, appearing in the moth state about a month later. 
The moth is larger than the one from the Striped Cut-worm, being 
nearly two inches across the wings; and differs from those belonging 
to the genus Agrotis in having little tufts of hairs on the back of 
noth the thorax and abdomen, while in the male there are broad, fan- 
ike tufts at the end of the body. The outer ends and base of the fore 
wings are dark ash-gray, the middle part rich reddish-brown, while 
he ordinary spots and a band across the outer part of the wings are 
)f a lighter erray than the base. There is also some of the reddish- 
irown sprinkled over all parts the w r ing where brown is not the 
ground color. 
THE FALL ARMY-WORM —(Laphygma frugiperda) —Guenee. 
The first notice we have of the destructive habits of this caterpil- 
ar is in the American Entomologist, Vol. 2, page 43, where the edi- 
ors state that they had received numbers of these larvae fm>m Mr. E. 
)a ggy> of Tuscola, Illinois, in July, 1868, and that they eat into the 
leart of young corn plants in Central Illinois, besides feeding exter¬ 
nally on the leaves. In a subsequent article the insect was again 
eferred to and called Prodenia Daggyi , or Daggy’s Corn-worm, in 
nonor of Mr. Daggy who first called attention to it. By this time it 
vas found that it not only ate corn, but was also very destructive 
ome seasons to lall-sown wheat and rye, as well as grass and some
