rarely breeds in corn, while the breeding plant of ' sculptilis is 
unknown, and the fact that it is sometimes taken free in fall 
makes it unlikely that the adult hibernates commonly w T here the 
larva feeds. 
Until the needed facts concerning the less known species are 
ascertained, we can only suggest that the encouragement of the 
prairie birds,—especially such as the black-throated bunting, the 
meadow lark, and the quail, which feed mostly upon insects col¬ 
lected on the ground,—the draining and cultivation of swampy 
tracts covered with coarse grass, and the insecticide measures 
common to an intelligent agriculture,—such as the burning of places 
of resort for hibernating insects,—will be suitable safeguards 
against these species.. In case their attack is anticipated or early 
detected, the application of Paris green or London purple about 
the base of the plants would in all probability protect the corn,— 
a measure of easy application and not excessively expensive.
