caterpillars assembled beneath killed. This method proved ol so 

 great value in the exterminative work against the gipsy moth, 

 that thousands of trees were banded during the latter part of the 

 caterpillar season. The trouble with the two last named methods 

 is that they are quite expensive though very efficient, and on that 

 account their employment will be restricted largely to shade trees 

 and ornamentals in parks, where expense is a question of minor 

 importance.

A few only of the more important and valuable works relating 

 to this insect are cited. The first named, by Messrs Forbush 

 and Fernald, is by far the most comprehensive volume and includes 

 everything of value relating to this insect up to the time of its 

 publication.

This species, a more recent introduction than the gipsy moth, 

 has already attained a much wider distribution and promises to 

 develop into a serious pest of fruit, shade and certain forest trees. 

 It will prove exceedingly difficult to control this pest in forest 

 areas if it becomes at all abundant and destructive. This insect 

 is not only injurious to the foliage of trees, but the barbed hairs 

 of the caterpillar, falling upon human flesh, may produce a severe 

 and occasionally dangerous irritation. This latter phase of the 

 trouble has been so serious as to cause the board of health of the 

 citv of Boston to give a public hearing on the subject in 1901. 



Destructiveness. The caterpillars are very voracious, feeding 

 by preference on the foliage of both apple and pear [pi. 8, 9], wild 

 cherry and white oak, though they thrive on both soft and hard 

 maples and also elm. They are exceedingly abundant in the 

 Middlesex Fells and other extensive wooded areas north or north- 

 west of Boston, and last spring defoliated large tracts of white
