a little tobacco into the hearts of the plants, where it would lodge and 
stifle the Lice, would be sure to do good. 
Waterings with some plant stimulant, such as nitrate of soda, 
would also do good in keeping up a strong healthy growth. 
This Aphis frequents Charlock, Shepherd’s Purse, and Wild 
Radish, all common weeds, and clearing off* these early in the year 
would prevent these pests going on from them to the cultivated crops. 
Cabbage and Tnrnip-root Maggot. 
Cabbage Fly. Anthomyia Brassicce, Bouche. 
Root Fly. A. radicum, Curtis. 
Radish Fly. A. floralis, Fallen. 
1, larva of A. Brassicce; 2, 3, pupas, nat. size and mag. ; 4, A. radicum, mag.; 
5, nat. size ; 6—9, A. tuberosa , larva and fly, nat. size and mag. 
The attacks of “ Cabbage and Turnip Maggot,” like those of 
Wireworms, Daddy Longlegs grubs, &c., are best described, for. com¬ 
mon purposes, under the common English name, as there are at least 
three sorts so much alike in appearance, and in method of injury, that 
it is very difficult to tell them apart. 
These three kinds of maggot are all much like the kind figured, 
magnified above at 1, whitish or yellowish, and legless, tapering to the 
head and cut short at the tail,—in fact, very like the well-known 
Onion maggot. They feed in or on roots of Turnip and Cabbage, as 
well as other plants, and in some cases in dung, and in a few 
weeks turn to chrysalids (figs. 2, and 3 magnified), from which very 
shortly a new brood of Flies comes out, which is directly in a condition 
to lay eggs and start a new attack. 
These three kinds are all small two-winged blackish or greyish 
Flies, all of them much of the shape figured at 4, magnified ; the 
cross lines at 5 give about the real length of the body and spread of 
the wings.
