Vertex broader and blunter than in pdidna ; the margins scarcel}' 

 raised above the disk; a faint median carina on its front half; the 

 central depression close to apex. Antenna? about as long as the head 

 and pronotum, plainly flattened, the middle segments about twice as 

 long as broad. Median carina of pronotum cut a little behind the 

 middle by the principal sulcus. Tegmina reaching tip of abdomen 

 in the female and tip of hind femora in the male; often shorter. 



Color: Either green or brown, much as in pelidna, but the median 

 row of spots on tegmina smaller and fewer in number, and sometimes 

 wanting. The dark bar behind the eye is more faint than in that 

 species, and seldom crosses onto the basal third of pronotal disk. 

 Hind femora greenish or brownish, not banded. Hind tibia\ dull 

 brown or yellowish, without paler ring near their base. 



Measurements: Length of body, male, 14 mm., female, 18 mm.; 

 of antennse, male and female, 6 mm.; of tegmina, male, 12 mm., 

 female, 13 mm.; of hind femora, male, 9 mm., female 11 mm. 



This species is also known in Indiana only from Lake County, a 

 single pair having been taken July 24, 1902, from the side of a rail- 

 way a mile southeast of Hammond. Tt is liable to be found anywhere 

 in the State as its range is given as "Nova Scotia to Texas.'' In 

 northern Illinois McNeill found it confined to the tops and sides of 

 hills. Morse has written of it as reaching maturity in New England 

 the first week in July, and being "one of the most plentiful and wide- 

 spread of our locusts, but owing to its small size and non-migratory 

 habits it does not attract the attention given to the larger and con- 

 sequently more destructive species. While somewhat local, it is found 

 nearly everywhere on dry. sandy or loamy soils. It moves chiefly by 

 leaping, but readily takes wing on occasion, flying, however, but a 

 few feet. Active and alert in the hot sunny weather of midsummer,
