Melanoplus femur-rubrum 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 12 (Nos. 

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

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

 (Nos. 153, 179, and 180). As Hart ('06, p. 8r) has remarked, it 

 is common in cultivated areas. Cultivation appears to be distinctly 

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

 in waste places. 



LOCUSTID^ 



Scudderia texensis Sauss.-Pict. Texan Katydid. 



This is the common and characteristic katydid of the prairie 

 areas. It was found (Sta. 1, 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. I2 (No. 

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

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

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



Conocephalus sp., nymph. 



A large female nymph was secured on blue-stem Andropogon 

 (Sta. 1, g) Aug. 24 (No. 159), having been captured by a crab- 

 spider, Misumena aleatoria Heiitz. 



Orchelimum vulgar e Harr. Common Meadow Grasshgpper. (PI. 

 XL, figs. 2 and 4.) 

 This grasshopper was taken east of Charleston on the flowers of 

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

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

 ers of rattlesnake-master, Bryngium yuccifolium (No. 178) ; and 

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

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

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

 places — particularly in the tall prairie grasses Andropogon and 

 Sporoboliis (Sta. \,g), where the first specimen (No. 3) was tal<en 

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

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

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

 and Spartina (Sta. l,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.
