cultivation. The only collecting was done in a limited bit of roadside 

 where the banks were occupied by a mixed growth of two tall bunch- 

 grasses, Trldens para and Andropogon furoatus. My visit to this spot was 

 made August 30. At that time the following species were taken or ob- 

 served, all being fairly frequent: Melanoplus femur- rub rum, Melanoplus 

 atlantis, Oonocephalus strictus, Dissosteira Carolina. Syrbula admirdbilis 

 and Arphia xanthoptera. 



10. This locality is on the east side of the Wabash about three 

 miles north of Lafayette and a mile southwest of Wild Cat Creek. At this 

 point there is a well-marked bluff marking the dividing line between the 

 upland, here formed by Sioux sandy loam, and the Wabash bottoms. At 

 the base of the bluff is an extensive marsh, shown on the Bureau of .Soils 

 map as a crescent-shaped patch of muck. The upland immediately bor- 

 dering the bluff is occupied by a cemetery in which there are many large 

 trees, the whole forming an open grove with no undergrowth except the 

 ordinary blue-grass sod. In this cemetery, frequenting the relatively dry 

 blue grass were numerous examples of Melanoplus scudderi and Melano- 

 plus luridus along with the usual Melanoplus femur-rubrum. and Encopto- 

 lophus sordidus. On the steeper slopes, where there was a considerable 

 amount of herbaceous undergrowth and some patches of Andropogon fur- 

 catus, a few examples of Spharagemon bolli were seen and, near the base of 

 the slope, in a shallow depression, where there was a thick growth of a 

 bright green, succulent grass, a small number of Stauroderus curtipennis 

 were found. Dissosteira Carolina was as usual common on paths and drive- 

 ways both on the upland and in the bottom. The swamp at the base of the 

 bluff was quite open and was of the type usual to the bottoms with rice cut- 

 grass, H omalocenchrus oryzoides, forming the dominant vegetation of the 

 wetter areas. On the side toward the bluff this growth was bordered by a 

 thicket formed mostly by tall herbaceous plants among which sunflowers 

 and goldenrods were conspicuous ; while on the opposite side toward the 

 open bottom lands it was bordered by a weed vegetation in which a 

 tangled growth of smart-weed (Polygonum) predominated. In the rice 

 cut-grass the common Orthoptera were Melanoplus femur-rubrum, Cono- 

 ccphalus brevipenms, Orchelimum nigripes, Orchelimum vulgare and Mela- 

 noplus differentialis. Both of the last-named species and also Oonocepha- 

 lus nigropleurum were frequent in the surrounding thickets, while Or- 

 chelimum vulgare and Melanoplus femur-rubrum swarmed in the Polygo- 

 num areas. In addition to the two forms last mentioned other species tak-
