ORTHOPTEEA OF INDIANA. 281 



• 



mina much exceeding the abdomen in both sexes, in our species 

 grayish or light brown in color, sprinkled with many small dark spots. 

 Inner wings with the basal half light yellow; the apical third trans- 

 parent; a narrow curved black band intervening. Hind femora of 

 average width, reaching or exceeding the tip of abdomen in both 

 sexes. 



McNeill, in the latest monograph of this genus, describes and gives 

 keys to 54 nominal species belonging to it. Of these, 49 are from the 

 United States, 16 of which are confined to California; while but three 

 occur east of the Mississippi Eiver. Of these, two have been taken 

 in Indiana.

Size, medium. Pronotum with the median carina low throughout;

 length of wing; the apex transparent. Inner face of hind femora
