Of these plants, corn, rice, and clinfas are infested wherever they 
are grown in the hill-bug section of the State, so far as we have observed. 
Of these plants, rice seems to be the favorite food where it can he 
secured, followed by chufas and corn. The reason for placing clinfas 
ahead of corn is that around Raleigh, so far as observed, bill bugs 
are plentiful on chufas, but do not trouble corn even when they are 
growing side by side. The various species of cyperus will undoubtedly 
have to be considered as the native food plant of this species in spite 
of the fact that it has been reared from other grasses (Figs. 11, 12, 13). 
According to Webster (1912), the following plants have been reported 
as food plants for this species from various parts of the country:

“Dr. Forbes gives Cyperus strigosus as the natural food plant, in the 
roots of which it develops in Illinois. Mr. T. D. Urbahns found it 
developing in Tripsacum dactyloides at Plano, Tex., in July, 1909. At 
Appleton, Tenn., July 14, 1911, Mr. George G. Ainslie found the in¬ 
fested fields in part grown up with weeds and a swamp carex ( C. vul- 
pinoidw ), but he was unable to find the beetle actually developing 
therein. (See PI. IX, figs. 1, 2.) Mr. A. X. Caudell reported the 
larvse injuring the roots of yellow nut-grass ( Cyperus esculentus ) at 
Stillwater, Okla., in 1895. Dr. Chittenden reared the adult from a 
pupa found in the roots of Panicum capillare growing in low bottom¬ 
lands along the canal near Glen Echo, Md., in August, 1897. Mr. I. J. 
Condit found it breeding in Frank’s sedge ( Carex franlcii) growing on 
the Department farm at Arlington, Ya. In Florida the insect develops 
from egg to adult in Cyperus rotundatus, while farther north, in the
