Melanophis femur-riibrmn DeG. Red-legged Grasshopper. (PI. 

 XXXIX, fig. 2.) 

 This species also is one of the most common and generally dis- 

 tributed insects upon open areas. It was found among the prairie 

 grasses Andropogon and Sporoholus (Sta. I. g) Aug. 8 and I2 (Nos. 

 3 and 39) ; in the Lepachys colony (Sta. I, e) Aug. 12 (No. 40) ; 

 and in Blyinus and Spartina (Sta. I, a and c) Aug. 24 and 28 

 (Nos. 153, 179, and 180). As Hart ('06, p. 81) has remarked, it 

 is cornmon in cultivated areas. Cultivation appears to be distinctly 

 favorable to it ; differ entialis, on the other hand, seems to thrive best 

 in waste places. 



LOCUSTID^ 



Scudderia texcnsis Sauss.-Pict. Texan Katydid. 



This is the common and characteristic katydid of the prairie 

 areas. It was found (Sta. I, g) among the tall swamp milkweeds 

 Aug. 8 (No. 2) ; in the tall blue-stem Andropogon and in Panicum 

 Aug. 12 (No. 44) ; in the Lepachys colony (Sta. I, e) Aug. 12 (No. 

 40) ; and among the swamp prairie grasses Spartina and Blynuis 

 (Sta. I, a and c) Aug. 28 (Nos. 179 and 180). Consult Hancock, 

 '11, pp. 330-331, for the life history of this species. 



Conocephohis sp., nymph. 



A large female nymph was secured on blue-stem Andropogon 

 (Sta. I, g) Aug. 24 (No. 159), having been captured by a crab- 

 spider, Misumena aleatoria Hentz. 



Orchelinmm vidgare Harr. Common Meadow Grasshopper. (PI. 

 XL, figs. 2 and 4.) 

 This grasshopper was taken east of Charleston on the flowers of 

 broad-leaved rosin-weed, Silphium terehintJnnaceum (Sta. Ill), Aug. 

 26 (No. 175) ; on the Loxa prairie (Sta. II) Aug. 27; on the flow- 

 ers of rattlesnake-master, Eryngimn yuccifoliuni (No. 178) ; and 

 on the prairie north of Charleston from the colonv of wild rye, 

 Blymus (Sta. I, a), Aug. 28 (No. 179). A scjueaking individual 

 (No. 180) captured here confirmed observations made in other 

 places — particularlv in the tall prairie grasses Andropogon and 

 Sporoholus (Sta. ^,g), where the first specimen (No. 3) was taken 

 Aug. 8. Nymphs, very probably of this species, were also in the 

 prairie grasses Andropogon and Sporoholus (Sta. 1, g) Aug. 8 (No. 

 3) ; and Aug. 28 (Nos. 179 and 180) in the swamp grasses Blyinus 

 and Spartina (Sta. I, a, c). This species is preeminently a tall-grass 

 frequenter, whose penetrating seeing during the sunny hours serves 

 to locate grass plots and low, rank weedy growths.
