 Orthoptera 



ACRIDIID/E 



Syrbula adjnirabilis Uhler. 



One specimen of this grasshopper was found in the tall prairie 

 grasses blue-stem Andropogon and Panicum (Sta. 1,^7) Aug. 8 (No. 

 3). Morse ('04, p. 29) says this species frequents "open country" 

 and is "common in upland fields amiid Andropogon and other coarse 

 grasses." 



Encoptolophus sordidus Burm. Sordid Grasshopper. (PI. XXXIX, 



One nymph of this species was taken in the prairie-grass colony 

 north of Charleston (Station I, g) Aug. 12 (No. 44) ; another (No. 

 158) on Aug. 24 in the colony of Lepachys pinnata (Sta. I, e) ; and 

 an adult (No. 48) Aug. 13 at Loxa (Sta. II, a) from the flowers of 

 Silphium intcgrifoliitm. 



This is a species characteristic of dry open places, where the 

 vegetation is low. The peculiar snapping sound made by the male 

 when on wing is quite characteristic. (Cf. Hancock, '11, pp. 372- 

 373-) 



Dissosteira Carolina Linn. Carolina Grasshopper. (PI. XXXIX, 



fig- 4-) 



A very reddish specimen of this species was taken in a cleared 

 bottom forest at River View Park, about three miles southeast of 

 Charleston, Aug. 19 (No. 95). Many specimens were observed in 

 the pasture above the "Rocks," on the Embarras River about three 

 miles east of Charleston. These individuals exhibited to a marked 

 degree the hovering, undulating flight which is so characteristic of 

 this species during the hot days of summer and early autumn. Town- 

 send (Proc. Ent. Soc. Wash., Vol. 1, pp. 266-267. 1890) has made 

 interesting observations on this habit, and finds that it is mostly the 

 males which participate in this courting ceremony, as he considers it. 

 There appears to be more or less of a gathering of individuals when 

 one of the locusts performs. There were perhaps half a dozen per- 

 forming in the colony observed at the "Rocks." Townsend (Can. 

 Ent., Vol. 16, pp. 167-168. 1884) has considered this flight as re- 

 lated to breeding. Some one might study this subject with profit, 

 and determine its meaning. Poulton's paper "On the Courtship of 

 certain Acridiidae" (Trans. Ent. Soc. London, 1896, Pt. II, pp. 233- 

 252) might prove helpful in this connection. 



This species seems to have been influenced by man to a marked 

 degree. Its original habitat appears to have been natural bare spots,
