 notable for its injuries to f^aljhages, l>nt rejjortecj also as sometimes 

 abiuidant in timothy, and in one case destructive to oats. It is included

r)f this common and widely distributed relative of the army- worm, 

 the obtainable data are remarkably imp(!rfect, and further information 

 is much to bc! desired. The species is generally distributed east of the 

 Rocky .Mountains, north into Canada, but seems not to occur in the 

 Southern States. Jknitenmuller says that it is common in New York, 

 and that the larva feeds on grass, cf)rn, wlujat, oats, timothy, etc. Web- 

 ster swept it from young wheat in Arkansas. All icr-ords agree that 

 it feeds on speci(!S of the grass and grain family.
