New YorK AGRICULTURAL EXPERIMENT STATION. 207 
The leaves which had begun to droop were utilized in forming 
the cocoon. Plate XXXVI, Fig. 1, is from a photograph of the 
same cocoon taken the next day. The leaves have been cut away 
showing the cocoon. It was supported on all sides by strands 
of silk but did not touch the leaf at any point. The caterpillar 
was still working on the inside of the cocoon when this picture 
was taken. The picture shows the cocoon enlarged to about 
four times natural size, the actual length being about one inch. — 
Plate BaXX Vi, Fig. 2, is from a photograph of the same cocoon 
taken three days later. It has been cut open showing the living 
chrysalis inside enlarged in the same proportion. Plate XXXV, 
Figs. 14 and 12, are from photographs from life showing the 
male and female moths, natural size. At Fig. 2 some of the cater- 
pillars are shown assembled on the trunk of a plumb tree. They 
had molted a short time before the picture was taken and their 
old skins are seen to the right of the group attached to the bark. 
NOTES ON METHODS OF COMBATING THE FOREST-TENT 
CATERPILLAR. 
The principal methods of combating this insect are given in 
Bulletin 159, pages 53-56. - The following notes are largely from 
the past season’s observations. 
ORCHARD TREES. 
Destroying the egg masses.—This is most conveniently done while 
_ pruning the trees. In the vicinity of Geneva and in other 
sections of the State this method has been practiced extensively, 
One orchar@ist sent his men through a large plum orchard a 
second time in search for egg masses of both the forest and apple 
tree tent-caterpillars with the result that a large number were 
collected and when spring came hardly a caterpillar of either 
species. could be found in the orchard. The year previous this 
orchard was badly infested with both species. 
Banding the trees.—This is principally a preventive but to 
some extent a remedial measure. Trees that are small enough 
to be jarred are banded to prevent the dislodged caterpillars
