was reported at Kittery, Me., as early as 1899, by the late Prof. F. L. 
Harvey. It has also been reported by Prof. .James Fletcher, the 
Canadian Government entomologist, as occurring at St. Johns, New 
Brunswick, where it was supposed to have been transported by 
steamers plying between Boston and St. Johns. In 1902 the moth 
was abundant in all the towns along the eastern division of the Boston 
and Maine Railroad, as far as Portsmouth, N. H. During the last 
two years, and especially the summer of 1904, the moth must have 
extended its ravages considerably in both New Hampshire and Maine. 
Its occurrence at Nashua, N. H., has been referred to in the discussion 
of the gypsy moth. The counties of Rockingham, Hillsboro, and 
Stafford, N. H., are known to be pretty generally infested. 
Strong gales of wind at mght during the flying season must extend 
the distribution of this moth many miles. This was illustrated by 
the results of the high gales prevailing in New England July 12-14, 
1897, which were largely responsible for the spread of the moth over 
much of the area now infested. The ability of this moth to extend its 
range over much of northeastern United States in the near future is 
abundantly shown by this instance and its history up to the present 
time. 
The control of this moth will need, perhaps, less of town and State 
aid than the gypsy moth, but some provision should be made to 
enforce the removal of the caterpillars’ webs in winter, and the 
authorities charged with the work against the gvpsy moth should be 
empowered to enforce corrective work against the brown-tail moth 
also. In the introduction of parasites for the gypsy moth the brown- 
tail moth should also be considered. These two insects have many 
common natural enemies, but the special enemies of each should be 
introduced. For detailed information on the history of the brown- 
tail moth and on means of control, reference is made to the publica- 
tions cited above.
