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

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

 beetle, ChaiiliognatJms pcnnsylvanicus 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. 



Xiphidhim attenuatiim Scudd. Lance-tailed Grasshopper. (PI. XL, 



fig. /•) 

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



rosin-weed, Silphium integrifolium, 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." 



Xiphidinm strictiim Scudd. Dorsal-striped Grasshopper. (PI. XL, 



This prairie species was taken on prairie clover, Petalostemiim 

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

 Lcpachys piniiata (Sta. i,e), Aug. 20 (No. 40); on the mountain 

 mint Pycuanthcmiim flexiwsum (Sta. I) Aug. 12 (No. 35); on P. 

 flexiiosum or P. pilosiim (Sta. II) Aug. 13 (No. 57) ; among the 

 swamp grasses Blyinus 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, Petalostciumu pur- 

 pur ewn (Sta. II), Aug. 13 (No. 50). 



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

 and, larp^ely, other vegetable tissues. He also states that it frequents 

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

Q^canthus nigricornis Walk. Black-horned Meadow Cricket. (PI. 

 XL, fig. 5, PI. XLI, figs. I and 2.) 



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

 (Lcpachys piiinata) colony (Sta. 1, e) Aug. 12 (No. 40); on the 

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

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

 (No. 179). 



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

 every 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 especially abundant
