even burrow right up the stem (Fig. 8, b), as seen in some specimens 
sent by a correspondent of the Board of Agriculture from Cornwall. 
I 11 turnips they burrow into the root and may cause (and also to some 
extent in cabbages) swellings, somewhat after the manner of the 
Turnip Gall Weevil (Ceuthorhynchus sulcicollis). I know of no records 
in this country of their attacking the leaves, but Dr. Biley found them 
in America burrowing into the stout midribs of cabbage-leaves in the 
summer ; a similar habit having been noticed by Mr. Fletcher, in 
a, Young turnip attacked and deformed by cabbage maggot ; 6, young cabbage roots 
tunnelled by maggots. 
1891, who at the same time observed them boring through the heads 
of winter cabbages in storehouses. 
The outer layers of the cabbage root are most attacked, the inner 
coie being too hard low down, but when they work to the upper part 
they enter the interior of the stem as seen in the specimen figured 
here. Sometimes so many larvae occur that they live upon the 
outside, of the decaying root as well as within ; in nearly all cases 
the moisture and slime in their galleries lead to rapid decay. Young 
plants that are affected can usually be at once detected by their 
leaves wilting.
