INJURIOUS INSECTS. 335 



where the insects have commenced and nearly completed their 

 growth by feeding on the grass or its roots, are by far the most 

 liable to attack. 



REMEDIES. After the ground is well fitted for the plants, 

 great advantage will result from placing newly mown grass, fresh 

 cornstalks, etc., in heaps about the plat. Coming to these by 

 night, the larvae will feed and crawl beneath, and may be cap- 

 tured and destroyed each morning. I have known large num- 

 bers to be thus entrapped. Securing those immediately within 

 the ground to be planted, however, is not alone sufficient. These 

 larvae have not sixteen legs for nothing, and especially is there 

 danger from immigrants if grass is grown contiguous to the 

 ground planted. It might be well to continue, in such a case, 

 to place the bunches of grass around the border of the planted 

 area, to still attract these night marauders. 



Sized paper, such as we usually write on, wound closely 

 about the plants, and held in place by banking slightly about 

 the base with earth, is a sure preventive, as the larvae can not 

 pass up its smooth surface. I .have known this to be practiced 

 with the happiest results. Care is only necessary that the paper 

 may closely encircle the plant, and that the banking be so 

 efficient as to surely hold it in place. 



Hand-work, digging out the larvae, is always to be com- 

 mended. No more injury need be expected from these trouble- 

 some " worms," if they are once in the grasp of an irate gardener, 

 who is disgusted at seeing his plants prostrate upon the earth. 

 And it must give rare satisfaction to dig the culprits out from 

 beneath the plants which their rapacity has simply cut asunder 

 and left to wilt, and aggravate the owner who had already 

 reckoned up and planned to expend the proceeds from the same 

 mutilated plants. 



Here, too, especially on light soils, it will be wise to set a 

 superfluous number of plants. 



Cabbage Leaf-Roller. Phitella cruciferarum. Family, 

 Tortricidce. Order, Lepidoptcra. While treating of cabbage 

 insects, I might describe the cabbage leaf-roller, or Cabbage 

 tineid (Plutella cruciferaruni), which little green "worms," or more
