Cut-Worms.

described, and habits recorded of some, and remedies given. They 

 are nearly all those which had been previously treated of by 

 Professor Riley. 



In an article entitled " Cabbage Cut-worms," contained in the 

 Report of the Entomologist to the Commissioner of Agriculture, 

 for the year 1884, Professor Riley has given a brief account of cut- 

 worms in general, the best approved remedies for them, and excel- 

 lent notices, averaging over a page each, of eight species that 

 depredate on the cabbage, each of which is finely illustrated, as 

 may be seen from the figures, which, through the kindness of the 

 Commissioner of Agriculture, we have been able to present in the 

 present paper. 



The above are, we believe, the principal publications upon cut- 

 worms accessible to the general reader. Reference to several 

 other writings upon those which are injurious to Indian corn, may 

 be found in a paper prepared by Mr. Thomas F. Hunt, and pub- 

 lished in Miscellaneous Essays on Economic Entomology by the 

 'State Entomologist of Illinois and Ms Assistants, 1886, pp. 64-66. 



List of Species. 

 As previously stated, no approximation to a full list of our cut- 

 worms can as yet be 

 given, since the larval 

 stage and habits of so 

 few of the species of 

 Agrotis, Mamestra, and 

 Hadena, are yet known. 

 It would not be safe to 

 presume, to any extent, 

 upon a genetic identity 

 of habits, since marked 

 differences have been ob- 

 served. For example, 

 Agrotis c-nigrum (Linn.) 

 and A. bicarnea (Guen.), Fig. 24 — mamestka picta Harris, 



according to Mr. S. L. Elliott, have been seen feeding by day, 

 without any concealment, on chicory, Cichorium intybus. Mamestra 

 picta Harris, the zebra cabbage worm (shown in Figure 24), feeds 

 exposed, in dense clusters, when young, upon several of its food- 

 plants, scattering with age, but continuing to feed by day without
