It is essentially a lowland form ; as its food plants clearly indicate, 

 and will therefore especially interest the farmer whose fields are of 

 bottom, swamp, or other low-lying lands.

FOOD PLANTS. 



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 Piano, Tex., in July, 1909. 

 At Appleton, Tenn., July 14, 1911, Mr. Geo. G. Ainslie found the 

 infested fields in part grown up with weeds and a swamp Carex (C. 

 vulpinoidea) , but he was unable to find the beetle actually develop- 

 ing therehi. (See PL IX, figs. 1, 2.) Mr. A. N. Caudell reported the 

 larvss 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 frankii) grow- 

 ing on the department farm at Arlington, Va. In Florida the insect 

 develops from egg to adult in Cyperus rotundatus, while farther north, 

 in the Carolinas, the common food plant is the "chufa" (Cyperus 

 esculentus). To such a degree is this true in the latter locality that 

 the insect is supposed by farmers to have been introduced with that
