SUBFAMILY III. LOCUSTIN.E. 313 



moulted, one of the most handsome. Tt probably occurs in all the 



counties, but is much 

 less common in the 

 northern ones. Fresh- 

 ly moulted, mature 

 specimens, from eggs 

 hatched in spring, 



Fig. 113. Male. Natural size. (After Lugger.) have been taken in 



Vigo County on June 18th, and on three different occasions nu- 

 merous specimens have been seen as late as November 22d. On 

 this date, in Marion County, when the government thermometer 

 rgistered 17 in the morning, several were flushed in the after- 

 noon, though a cold, raw wind was blowing. In the central and 

 southern parts of the State it is more abundant in mid-autumn 

 than in summer. There occasionally may be two broods in one 

 season. SLS I have found the nymphs common in Vigo Co. on Oc- 

 tober 15 and 21. 



This species is noted for its extended migrations and Avhen a 

 second brood appears, they are doubtless from eggs laid by ma- 

 ture specimens which have entered the State in early spring. 

 About 3 o'clock in the morning of April 11, 1893, the city of 

 Terre Haute, Ind., was visited with a severe storm of rain and 

 wind from the southwest. A number of buildings were unroofed 

 and many shade and forest trees twisted and broken off. While 

 on my way to the high school building several persons informed 

 me that they had, that morning, seen specimens of "gigantic 

 grasshoppers'' on the street, but were unable to capture them. 

 About 10 o'clock one of my former pupils brought me two living 

 specimens of S'. aincric<in<i, which she had picked up from the 

 sidewalk near her home. They had come sailing in on the wings 

 of the wind from some distant point in the southwest, where they 

 had passed the winter in the mature state or as an advanced form 

 of the young. 48 Mature individuals which had doubtless migrated 

 have also been taken in Lake County on May 13, and one is re- 

 corded by Fox (1910) as taken at Lafayette in late March. 



In the southern portion of Indiana, aincricanu is always found 

 in dry, upland localities, such as the borders of roads, old mea- 

 dows, weed and stubble fields, prairies, and especially in old aban- 

 doned fields which have grown up to oak and other shrubs. In 

 the northern portion it occurs in damper localities, being found 

 in the tall grasses and sedges along the borders of sloughs and 

 marshes and in the meadows bordering lakes and tamarack
