where it works beneath a very delicate web which it spins. 
In this respect it differs from the Brown Mite which does not 
spin a web. The eggs are deposited under the web and are 
globular and transparent. 
Remedies. — This insect thrives best in a dry atmosphere 
and the free use of water is probably as good a remedy as 
has been found. Apply often in the form of a spray taking 
pains to treat the under side of the foliage. 
In addition to the above, the Fruit-tree Leaf-roller and 
a Plant Louse also attack the rose. I have also been informed 
that the Rose Slug, an insect resembling the Pear Slug, has 
become a pest in Denver. The remedies for it are the same 
as for the Pear Slug. 
SHADE-TKEE ENEMIES. 
THE BOX- ELDER LEAF-ROLLER. {Carcvria seviifercuin, 
Walk.) 
ddiis insect isa close relative of the PTuit-tree Leaf-roller 
and it is quite commonly thought not to be different. It 
seems to confine its attacks exclusivel}^ to the box-elder, 
however, in this state, as I have never yet found the larvae 
feeding upon anything else. Its habits and appearance are 
much like the fruit tree species.
