planted in clover, I captured a female specimen of Schistocerca alutacea. 

 The capture was made close to the railroad, along which there was a 

 mixed growth of elder (Sambucus) and white melilot (Melilotus alba). 

 The latter formed a very rank growth in some abandoned gravel pits on 

 the opposite side of the railroad. The color of this specimen was much 

 duller than that of examples from the New Jersey sphagnum bogs, being 

 an olive brown or pale leather color with hardly a trace of green, and 

 with the dorsal stripe, although easily recognizable, by no means con- 

 spicuous. 



4. At this point some roadside collecting was done. The place is on 

 the slope leading from the "second bottom'' at West Lafayette to the 

 upland immediately north of the town. The roadside vegetation consisted 

 in the dryer parts of a mixture of blue grass and timothy and in the 

 gullies of a rank growth of MUlohis alba. The Orthoptera were all of 

 common types. Melanoplus femui^ntbrum swarmed everywhere, while its 

 congener, M. differentialis, was almost entirely limited to the thickets. In 

 the blue-grass-timothy areas Conocephalus strictiis was common, while Syr- 

 bula admirabilis was of frequent occurrence. 



5. This place, locally known as "the tank" fruin the presence of the 

 storage tank of the West Lafayette water company, is on the edge of the 

 upland at the head of a deep ravine known as Happy Hollow. It over- 

 looks the Wabash bottoms, "second bottoms" being absent from this point 

 north. The soil is Miami silt loam. The land was unfilled the past 

 season and had evidently hot been in cultivation for a long period. It was 

 open, but at its southern edge where it meets the steep slopes leading 

 down into Happy Hollow was bordered by the relatively dense woods 

 which clothe these slopes. The open areas were closely covered with blue 

 grass with which were locally intermixed small areas or scattered clumps 

 of wiregrass, Poa compressa, and foxtail, Ghcetochloa glauca. There were 

 also considerable clover and some low trailing briers. Clase to the woods 

 the blue grass became rather sparse and grew only in short scattered 

 (•lumps with open places between where the bare soil was exposed or where 

 certain hardy herbs, mostly composites, grew. In one or two places on the 

 higher land where the blue grass was very thin, were formations of Andro- 

 pogon scoparius with .1. furcatus as a minor constituent. At one place 

 immediately adjoining the woods was an extensive patch of Tridens flora. 

 Within the outer edge of the woods on some level stretches where the less 

 eroded parts of the bluff project out into the ravine, were a few scrubby
