between the leaf-stalk and the branch, in which it finds a 
shelter during the day, issuing from it at night to eat the 
leaf so secured. It is stated that if it has eaten this leaf it 
also devours the newly formed wood, even burrowing for a 
short distance into the twig. The tips of the infested twigs 
usually die back as far as the base of the first perfect leaf, 
where a new bud fornis, which soon assumes the position of 
the one destroyed. As this new bud is late in starting, and 
never grows straight, the injury caused by these small 
worms interferes seriously with the growth of the trees, arid 
also mars their beauty. As long as young the caterpillar is 
pale greenish or yellowish-green, sometimes tinged with 
pink on the back. It has a yellowish head, with a black dot 
on each side; the cervical-shield is also yellowish. When full 
grown it measures about half an inch in length and itisnow 
of a dark flesh color; its body is marked with a number of 
small shining spots, and the head and horny cervical-shield 
are black. When about full grown it deserts the tunnel on 
the twig and constructs a yellow woolly tube or case upon 
one of the leaves, in which it lives, issuing at night to feed 
upon the neighboring leaves; if it has to move it drags its 
case along. Soon afterwards it closes the house with a 
silken door and tranforms inside to a pupa, from which the 
moth issues in about ten days. 
There is but one annual brood of this insect. Its fore- 
wings are white, mottled and spotted with greenish-brown; 
there is a large grayish-brown spot at the tip, mottled with 
white, and another towards the base of the wing, of a 
darker shade; the front edge is mottled with grayish-brown; 
the hind-wings are dusky. 
The insect has as yet not been found in our state, but 
very likely it has been over looked. It can be kept in check 
by the proper use of Paris-green or London-purple mixed in 
the proportion of one teaspoonful of the poison to two gal- 
lons of water. Hand-picking is also a great help, and most 
of these insects can be gathered while still in their burrows
