‘areas containing only scattered grasses, but with many low saplings and 
some herbaceous undergrowth. The woods on the upper portions of the 
ravine slopes adjoining the upland were of the mixed hardwood type. The 
dominant tree was the white oak, but with it were many hickories, elms, 
sugar maples, lindens, red oaks, beeches and dogwoods. 
Collections were made in the Open fields above the woods, along the 
borders of the woods and in the woodland scrub areas. In the more open 
areas, farthest from the woods, wherever the blue grass or its congener, 
Poa compressa, was thick and luxuriant, common species were Jelanoplus 
feomur-rubram, Enceoptolophus sordidus and Conocephalus strictus; Syrbula 
admirabilis was of frequent occurrence. Where the grass was shorter and 
coarser with some interspaces a number of additional species were com- 
mon such as MWelonoplus allanis, Arphia xanthoptera, Dissosteira carolina 
and Hippiscus rugosus. Of Arphia ranthoptera and Hippiscus rugosus both 
the yellow-winged and the red-winged types appeared to be about equally 
frequent. Both of these secies were common in the more barren areas 
along the very edge of the woods, where they were associated with 
Spharagemon bolli and Melanoplis luridus, each of which was of frequent 
eccurrence, but did not appear to spread any appreciable distance from the 
immediate vicinity of the trees. Within the woods in the scrub areas pre- 
viously referred to the two last-mentioned species were the only ones 
found. Other species occurring at this locality were Chortophaga viridifas- 
ciata and Orchelimum vulgare, long-winged phase. Nymphs of the former 
were frequent in some areas of dwarfed blue grass in spring and again in 
the fall, while a smaller number of the latter were found in a scrub area 
along the borders of the woods. 
6. This includes the outer edge of the Wabash bottoms a short dis- 
tance south of West Lafayette. The outer edge of the bottoms at this 
point is marked by a gently sloping bluff which leads up to the second 
bottoms of West Lafayette. Near the base of the bluff is a road and below 
the road, between it and the level surface of the present bottom, is a short 
slope which was partially wooded, the common trees being cottonwoods, 
honey-locust, hackberry, elm and shingle oak. The woodland here formed 
au narrow fringe and beyond it, occupying all the level areas, were the 
usual corn fields of the bottoms. Beneath the trees was a fairly dense 
undergrowth of shrubs and tall grasses of which species of Hlymus were 
most frequent, especially FH. virginicus. The soil was a mixture of the 
gravel derived from the material of the bluff itself and alluvium depos-
