The cut-worm was found to be Agrotis annexa 

 (Treits.), shown in Fig. 15, 

 in its three stages of larva, 

 pupa and moth. (Forbes, 

 Twelfth Report of the Insects 

 of Illinois, 1883, p. 103.) 



In another locality, of 500 

 cabbage plants and 300 

 tomato plants set out a week 

 later, but about 200 of each 

 had escaped the cut-worm.

 A writer, inquiring for a remedy for the cut- worm so destructive 



to young cabbage plants, states 

 incidentally, that one-half or more 

 of the young plants are cut down 

 in early spring, especially if the 

 nights' following their setting are 

 d cool or damp. 



Of the species preying upon cab- 

 bage are : Agrotis clandestina, A. 

 saucia, A. annexa, A. messoria, A. 

 n — malefida, A. ypsilon, Mamestra sub- 

 juncta, Mamestra trifolii, Hadena 

 FiG.i6.-MAM E sTEAsuB J uNCTA : a,head^ evastafrix and Laphygma fru- 



and collar; 6, a middle joint; c, the anal r axi J 



shield ; d, the moth. giperda. Mamestra subjuncta (Gr.- 



Rob.), is illustrated in Figure 16, as one of the most injurious 

 of the species to cabbage. 



Turnips. — A favorite method of attack upon the turnip is to eat 

 into and around the neck of the plant, until it is detached, or to 

 eat off separate leaves and drag them into the hole beside the plant* 

 to feed upon during the daytime. The turnip crop in England is 

 more liable to cut-worm attack than is the crop in our country, the 

 principal depredators being Agrotis exclamationis Linn., Agrotis 

 segetitm Ochs., Mamestra brassicce Linn., and Triphcena pronubd 

 (Linn.).
