Although it would seem from the above that the larva? are omniv- 
orous, the investigations of the writers disclose the fact that they 
show a decided fondness for the Graminese and probably would confine 
themselves almost exclusively to plants belonging to this order if 
always obtainable. 
RECENT INJURIES. 
This species is particularly injurious because it shows a decided 
fondness for attacking plants growing in sandy soil. Soil of this type 
generally is deficient in fertilizing elements and also suffers very 
quickly from drought. Consequently plants growing in such soil 
are not as thrifty and vigorous as those growing in loamy soils, and 
when attacked they lack vitality to counteract the injury and suffer 
more than do those in soils of more favorable nature. It frequently 
occurs that only certain portions of the field are of this sandy type 
and in such cases infestation is confined to the sandy areas, it often 
being difficult to find larva? in the rest of the field. 
During the summer of 1913 about 2 acres of sorghum in a field on 
the State farm near Columbia, S. C, was practically laid waste by 
the ravages of this species. The soil in this area was almost pure 
sand, while the rest of the field was sandy loam. In many instances,
