finely crenulate on both margins. The males usually have the 



anal plates formed into long, curved processes which readily 



distinguish them from the other genera of this group. The 



process from the supra-anal plate curves downward and that 



from the sub-anal curves upward, and both of them are notched 



at the ends. 



The species of Scudderia in general inhabit bushes, tall grass, 



and weeds, in meadows and along roadsides, especially in damp 



places. 



Key to Species. 



1. Supra-anal plate of male with a long decurved process 2 

 Supra-anal plate of male triangular, without a long de- 

 curved process (Fig. 53) septentrionalis 



2. Length of posterior femora 28 mm. or more 3 



Length of posterior femora less than 25 mm 4 



3. Notch of supra-anal plate broad, with minute median 



tooth, the lateral processes slender, the notch as wide 

 as the upturned sub-anal spine, the latter fitting into 

 the notch when in natural position (Fig. 49) . . . .texensis 

 Notch of supra-anal plate triangular, without a median 

 tooth. Lateral processes broadly rounded. Sub-anal 

 spine touching but not fitting into the notch (Fig. 50) 



curvicauda 



4. Notch of supra-anal plate triangular, as in curvi- 



cauda. Width of tegmina much greater than depth of 



body (Fig. 51) pistillata 



Notch of supra-anal plate deep, rounded, forming a 

 fork-shaped appendage with swollen lateral processes. 

 Width of tegmina not greater than depth of body
