Doctor Riley states that the oranulated cutworm. Felt i a tnine.m 

 Treitschke, probabl}- has three o-enerations in Georoia, and that it is 

 the most common cotton cutworm in the South. From the writino-s of 

 Doctor Riley and others, we believe that Aiji'oflx i/pnHoji Rott. has one 

 generation in the most northern States and two in the latitude of 

 St. Louis, Mo.

The average date of pupation of the hil)ernated lar\ ;e was, there- 

 fore, at)out April i^5, and thus the moths would emerge about the 



middle of Ma}'. Very evidently 

 the moth emerging July 8 is of a 

 second brood. 



The worms were observed feed- 

 ing upon onions, cabl)age, potatoes, 

 and cotton. A moth was taken at 

 College Station, May 11, 1903. 



Several pup.e were parasitized by

Previous recordx. — This species 

 tirst received careful consideration 

 in this country by Riley," who 

 summarizes the knowledge of the 

 species at the time of his wi'iting, and describi^s the larva' and eggs. 

 He states that there is either a dual method of hibernation or it is 

 double brooded. He records pu])ie received from a cotton field at 

 Americus, (ra. , A[)i'il 22, from whicii moths emerged April 2-1, 1879, 

 and a pupa from Virginia Point, Tex., received December 8, from
