166 AGRICULTURAL EXPERIMENT STATION. 



they are placed under loose bark of trees, about fences or under 

 rubbish. The chrysalis is formed in the cocoon in two or three days 

 and is of a reddish brown color, densely clothed with short pale 

 yellowish hairs. 



LIFE HISTORT. 



The eggs hatch about the time the buds burst and like the previous 

 species the larva can go for some time without food. While young, 

 they spin a slight web upon the trunk or branches which is not 

 usually noticed. The larva while youug manifest a propensity to 

 military movements, marching about in single or double file, and 

 when older wander about for exercise and food. They become full 

 grown in six weeks and soon spin a cocoon, as mentioned above, 

 from which the moth appears in two or three weeks and soon lays 

 its eggs, completing the life history. 



REMEDIES. 



Pick the egg clusters in winter. Knock the trees and the young 

 larva will suspend themselves by threads and can be removed by 

 swinging a stick to which the threads become attached. Put cotton 

 bands about the trunks to keep the wandering caterpillars from 

 ascending other trees. The natural enemies are numerous and hold 

 them in check. 



FALL CANKER-WORM. 



Anisopterix yometaria^ Harris. 



The eggs and female of this species were received at the station 

 this season. The female was taken in the act of depositing eggs 

 on an apple tree. The moths were quite plentiful about Orono last 

 fall This species has been known for a long time to feed on the 

 foliage of the apple tree, and also to attack the elm, cherry, peach, 

 &c The females being wingless and not being able to travel far, 

 this pest is usually local in its attacks. Whether it does much 

 damage in Maine we do not know, but regard it important that its 

 habits be known. 



DESCRIPTION. 



Perfect insect — (Male.) A moth provided with wings, the fore 

 wings, brownish gray, glossy, crossed by two whitish irregular
