CABBAGE. 
Cabbage and Turnip Root-gall Weevil. Ceuthorhynchus sulcicoliis, 
Gyll. 
CEUTHORHYNCHUS SULCICOLLIS.—1-5, gall and maggots, nat. size and mag. ; 6 and 
7, weevil, nat. size and mag.; 8, leg of weevil, mag. Also cocoon, and cocoon in 
earth-cell, and Cabbage-root with galls, drawn from life by Ep. 
The small knob-like excrescences on Cabb.ge-roots (and also on 
Turnip-bulbs), which are caused by the presence of the grub of a small 
weevil-beetle, are a most common malformation, and though the 
plants would be better without them, still they are not generally con- 
sidered to do very much mischief. Last spring, however, the first 
observations of their appearance (which were sent at the beginning of 
April) were of some especial interest, as showing that the grubs were 
in no way injured by the long-continued and very unusually severe 
cold of the preceding winter, which could only be said to begin to 
break up generally towards the end of February; and also the speci- 
mens sent showed in one instance, and on the broad scale of field 
cultivation (as they were samples of an intended purchase of 4000 
plants), an amount of serious injury from the severity of gall infestation 
which I have never met with before. 
On the 4th of April Mr. Steabbens, of St. Albans, sent me samples 
of a large number of Cabbage-plants submitted to him for purchase, 
all of which I found to be infested with weevil-galls. In a few 
instances the mischief was done, the gall was open, and the outside 
partly broken off and gone, as well as the maggot, but for the most 
part the grubs were still present. Some of the plants sent showed only 
a few of the lumps or galls, averaging about half an inch across; but
