The Gloomy Scale

insect. In the states south of this line, however, the insects seem to he 
generally distributed in cities and towns wherever maples have been 
used extensively for shade purposes. The map given in Fig. 2 shows 
very clearly the distribution of this insect. 
For the records outside of North Carolina my thanks are due to Mr. 
E. R. Sasscer, who has kindly sent me the records from the United 
States Bureau of Entomology, and to the entomologists of various states 
in the gloomy scale region who have very kindly summarized the condi¬ 
tions in their states. 
DISTRIBUTION IN NORTH CAROLINA 
In North Carolina the gloomy scale does not occur beyond what is 
generally accepted as the western boundary of the Upper Piedmont. The 
map in Fig. 3 indicates very well the distribution of this insect in the 
State. The records are based upon correspondence and careful mspec-

been found. The small rings indicate places inspected, but no scale found. 
tion of all of the large cities and towns of the State. Its prevalence in 
the eastern part of the State is apparently dependent upon the extent to 
which soft maples have been used for shade purposes.. In all of the 
larger cities and towns in the eastern part of the State it is practically 
impossible to find soft maples of any size which are not seriously 
infected with the gloomy scale. 
An effort has been made to determine the western extent of this scale, 
and certain towns along the border have been visited with this m view. 
The localities in which it has not been found are also indicated in the 
accompanying map. We may look, therefore, for this scale everywhere 
in the Piedmont and Coastal Plain sections of the State where soft 
maples have been planted extensively. 
NATIVE HABITAT 
In the present day of world-wide commerce the native habitat of any 
species of insect becomes of interest. Due to the introduction from for-
