ing near, and somo were found also on the trunk of the clierry tree itself. These little 

 pieces of leaf were all hollowed out between the upper and lower skins or epidermises 

 and in the hollows thus made were tiny grubs, each piece of leaf constituting the home 

 of a single grub. A number of the little cases were placed in suitable breeding-cages 

 and in the early spring the little moths commenced to emerge, continuing until the 

 middle of May, at which time they probably emerge out of doors. The insect in its 

 different stages is shown in Fig. 9.

On September 1, 1808. the same insect was observed to be working on the same tree 

 part of the cases already cut out, while in other instances the insects were still in the 

 mines getting ready to cut around tlicmselves and thus transform the mines into cases. 

 It is a fact worthy of note that while many of the leaves of the cherry remained on the 

 tree at the time when the larvae were tying their cases up for winter, no cases weie 

 fastened to the cherry leaves, but almost all of them to the evergreen trees near by. 

 or to tlie twigs and bark of the cherry tree itself, instinct thus guarding against the 

 use of destructible supports. 



While a healthy tree can easily witlistand tlie attack of a few insects of this sorl. 

 the efl'ect becomes more serious as their numbers increase, though if the insect would 

 confine its attention to wild cherries no great harm might result. Unfortvmately this 

 case-bearer works al.so on a])})le and thorn-apple, as well as occasionally on pear, and 

 its work is sometimes veiy serious. Luckily it is fairly conspicuous and easily reco,L:-
