CABBAGE. 
On the lOtli of March Mr. Martin Burt let me have some further 
supply of specimens, with the remark, “In digging them out this 
morning, being frosty, I find some of them retired quite into the solid 
ground, in a cavity just fitting them.” A few days later, Mr. Burt 
added, “ To-morrow I am going to cultivate as deeply as possible 
between the rows of Beans, in hopes of turning out a good many of 
the pests and destroying their runs.” This plan might be expected to 
act well, for the grubs were obviously sensible to weather influences, 
and turning them out of their nests would act as strongly on them as 
on the “ Surface-caterpillars,” which are best got rid of by throwing 
them up in cold and wet. All measures of treatment suitable for 
clearing “ Surface-caterpillars ” (see paper on this pest) would be 
applicable to these grubs also. 
Further information as to attack by this grub would be very 
useful. Its smaller size and white tint distinguish it from the 
common “ Surface-caterpillar.” 
CABBAGE.

Linn. ; A. cheledonii, Latr. 
Aleyrodes proletella.

On the 21st of March a piece of Broccoli leaf was forwarded to me 
from Hoe Court, Colwall, Malvern, by Miss Raper, which had been 
brought in that morning, covered with the small insect sometimes 
known as “ Snowy Fly,” or, from its likeness to a very minute moth, 
as “ Motli-bliglit.” It was mentioned that the whole crop was spoiled 
by it, likewise that it had not been observed before.
