The leaves wbicb had begun to droop were utilized in forming 

 the oocoon. 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 side's 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 XXXVI, Fig. 2, is from a photograph of the same cocoon 

 taken three days later. It haiS been cut open showing the living 

 chrysalis inside enlarged in the same proportion. Plate XXXV, 

 Figs. 1 1 and 1 ^, are fro'm photographs from life showing the 

 male and female moths, natural size. At Fig. 2 some of the cater- 

 [Hllars 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 53-5G. 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 orchardist sent his men through a large plum orchard a 

 second time in search for egg masses of both the forest and ap])]e 

 tree tent-caterpillars with the result that a large number were 

 collected and when spring came hardly a caterpillar of eith-2r 

 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
