On August I, 1892, I visited Lake Maxinkuckee, Marshall Co., 

 Indiana, and in a sandy, fallow field, near the south-western border of the 

 lake, I found this locust to be quite abundant in company with Spharage- 

 mon bolli, Scudder. They never leaped when disturbed, but used the 

 wings to propel them in a flight of about 30 yards ; the males making a 

 faint crackling noise as they cleared themselves from the earth, while the 

 females were noiseless. A number of pairs were taken in copulation on 

 this date. 



On August 17, 1893, I again visited the locality, and found the field 

 to be in corn, but the Spharagemon was very common over about two 

 acres of the most sandy portion. Resting on the soil between the rows, 

 they were very difficult of detection, and eight times out of ten were not 

 seen until flushed, unless they had previously been " marked down " as 

 they alighted. A few were also taken from the sandy margin of the lake, 

 but careful search over a wide extent of territory failed to reveal them 

 elsewhere. 



Without specimens for comparison, and from the literature at hand, I 

 determined them doubtfully as Spharagemon co/lare, Scudder, and sent 

 specimens so named to Prof A. P. Morse, who was making a detailed 

 study of the genus. He found that they differed from the type specimens 

 oi collare in Mr. Scudder's collection, and so described them as new, under 

 the name cited above.
