 black on the margin. The first brood 

 of cater[)illars occurs in May, and the 

 second in the autumn; and when very 

 numerous they do considerable injury 

 to cabbages and plantations of horse- 

 radish. The caterpillar is eight or ten 

 lines long, with the head of a light

 Almost the only method of destroying 

 these caterpillars, is to hand-pick them, 

 which, from their small size, will be 

 very tedious; if, however, a mat or 

 piece of linen be laid under the infest- 

 ed plants, they may be shaken into it, 

 and thus a great number be collected 

 in a short time." — Gard. Chron.
