Blatchley ('03, p. 384) has observed the species feeding on small 

 moths, and once saw an individual on goldenrod eating a soldier- 

 beetle, Chauliognathus pennsylvanicus DeG. Forbes ('05, p. 144) 

 reports that its food consists mainly of plant-lice, and leaves of grass, 

 fungus spores, and pollen. It is thus evident that it eats both animal 

 and vegetable food.

fig- 70 



On the prairie at Loxa (Sta. II), on flowers of the arrow-leaved 



rosin-weed, Silphium integri folium, a single individual of this species 

 was found Aug. 13 (No. 48). 



According to Blatchley ('03, pp. 380-381) it frequents the coarse 

 vegetation bordering wet places. He also states that the eggs are 

 placed between the stems and leaves of "tall rank grasses."

 fig. 6.) 



This prairie species was taken on prairie clover, Petalostemum 

 (Sta. I, b), Aug. 11 (No. 21) ; in sweepings among the cone-flower, 

 Lepachys pinnata (Sta. i,c), Aug. 20 (No. 40); on the mountain 

 mint Pycnanthemum flexuosum (Sta. I) Aug. 12 (No. 35); on P. 

 flexuosum or P. pilosum (Sta. II) Aug. 13 (No. 57); among the 

 swamp grasses Elymus and Spartina (Sta. I, a and ,c) Aug. 28 (Nos. 

 179, 180) ; on the Loxa prairie on Silphium integrifolium (Sta. II) 

 Aug. 13 (No. 48) ; and on purple prairie clover, Petalostemum pur- 

 pureuiih (Sta. II), Aug. 13 (No. 50). 



Forbes ('05, p. 147) gives its food as plant-lice, fungi, pollen 

 and, largely, other vegetable tissues. He also states that it frequents 

 the "drier slopes in woods and weedy grounds" (p. 148).

This prairie cricket was taken in sweepings from the cone-flower 

 ( Lepachys pinnata) colony (Sta. I, e) Aug. 12 (No. 40); on the 

 transitional prairie east of Charleston (Sta. Ill, b) Aug. 15 (No. 

 62) ; and from the swamp cord-grass, Spartina (Sta. I, c7), Aug. 28 

 (No. 179). 



Blatchlev ('03, p. 451) says: "In August and September, nearly 

 everv stalk of goldenrod and wild sunflower along roadsides, in open 

 fields or in fence corners, will have from one to a half dozen of these 

 insects upon its flowers or branches. It is also esoeciallv abundant
