The Terrapin Scale (Euleca- 
nium nigrofasciatum Perg.) 
The terrapin scale is nearly 
hemispherical, about one 
twelfth of an inch long, nearly 
as wide and high, and reddish 
in color. The surface is marked 
with darker, radiating spots or 
streaks, and usually there is a 
series of shallow depressions 
near the margin. The food 
plants include peach, apple, 
plum, cherry, quince, pear, and 
various shade trees. 
The seale is difheult to kill. 
The best remedy is spraving with 
20 per cent kerosene emulsion in spring, just before growth starts. Do 
not apply so much liquid that it will run down the trunk of the tree.
