A female specimen from northern Illinois in the collection 

 of the late A. Bolter, of Chicago, measured sixteen millimeters 

 in total length, this being the maximum size of any examples 

 examined. A series of specimens from St. Anthony Park, 

 Minn., furnished by the late Professor Otto Lugger presented 

 some departures from the usual form. There was variation in 

 the angularity of the vertex, the frontal margin of some 

 examples being inordinately obtuse, resembling Tcttix liig- 

 geri ; the median carina of the pronotum instead of the usual 

 straight profile was undulating in its backwards course; the 

 dorsum more decidedly rugose, while the posterior tarsal 

 characters were but little changed. 



The color is extremely variable in this species, and poly- 

 ornate, light or dark, fuscous, sometimes presenting yellowish 

 white lateral stripes, one on each side of the pronotal disc, 

 which may be continued forward on each side of the vertex. 

 Again, a light median longitudinal band may extend the entire 

 length of the pronotum, of uneven width, and rich black 

 pigmentation may be present on each side contrasting strongly 

 with the light band. Occasionally a light spot appears on 

 the pronotal disc. 



The light band on the dorsum of pronotum is remarkably 

 protective while these little locusts are in their natural habitat, 

 simulating the dried grass-blades perfectly. 



Variety 2. Pronotal process and wings more or less abbre- 

 viated; superior lateral sinus of lateral lobes less deep. In 

 this variety the posterior process extends scarcely beyond the 

 apex of the posterior femora and hardly passing the wings, or
