SOME INDIANA ACRIDID^l— III. 



BY W. S. BLATCHLEY, TKRRE HAUTE, INDIANA. 



In the two preceding papers of this series 36 species and 3 varieties 

 of Acrididae have been recorded as occurring in Indiana. Since the last 

 paper, published in the Entomologist for February, 1892, appeared, five 

 additional species have been taken within the State, and many facts have 

 been gathered concerning. the life history, habits and range of the species 

 previously recorded. Moreover, my private collection has been largely 

 increased by exchange for specimens from other parts of the United 

 States, and I have possessed myself of almost all the literature extant 

 upon the group, so that I am enabled to clear up a few mistakes in 

 synonymy which crept into my first papers.

This small locust was first taken in Indiana on July 6th, 1892, from 

 the sandy bed of the old Wabash and Erie Canal, five miles north of 

 Terre Haute, Vigo Co. Other specimens were secured at the same 

 locality in September of that year, and in September and October of 1893. 



On one side of the canal, at the point mentioned, is a large pond, 

 occupying perhaps 50 acres of the Wabash River bottoms, and on the 

 other side is a sandy hill or bluff of the river, which is covered with 

 typical prairie grasses and plants. The locust has been found only in an 

 area of about five acres, on the side of the hill, and in the bed of the 

 canal. When disturbed it leaps vigorously, and without noise, for several 

 times in succession ; then, settling down on a sandy spot, it will allow a 

 close approach, evidently relying upon the similarity of colour between its 

 body and the sand to shield it from observation. According to Bruner, 

 /oc. cit., it is a very common species west of the Mississippi ; but this 

 I believe, is its first record east of that stream, unless the species men- 

 tioned by McNeill, in his " Illinois Orthoptera,"* as Fhilobostroma 

 parva (?), be the same.
