This clumsy bodied insect is among the least common of our In- 

 diana Melanopli, having been taken only in Crawford, Knox, Mon- 

 roe, Vigo, Putnam and Clarion counties. Seldom more than a dozen 

 or two are seen each season. It frequents, for the most part, upland 

 woods and thickets, though it is sometimes found along the borders of 

 marshes and swamps, but never close to the water. It is more arboreal 

 than many of our locusts, having been taken in autumn on prickly 

 ash and buttonbush shrubs, several feet above the ground, and also 

 from the boles of hackberry and oak trees, where it was probably 

 sunning. Lugger states that in Minnesota "it is very common, pre- 

 ferring the edges of forests or places overgrown with bushes and 

 vines. The grapevine, especially, is preferred, by these locusts, and 

 they soon destroy its foliage by eating big holes in the leaves." 



In central Indiana hlatcltUiji begins to reach maturity by June 

 14th, and ragged, forlorn looking specimens have been seen as late 

 as November 3d. Its general range is west of the Mississippi. Marion 

 County, Indiana, being the most easterly point from which it has 

 been recorded.
