single example of each of the last two species being seen and only a single 
pair of Conocephalus nigropleurum. Noteworthy was the entire absence in 
this marsh of the two most frequent marsh “long-horned” grasshoppers of 
this region, Conocephalus brevipennis and the typical phase of Orehelimion 
nigrVipes. 
In the herbaceous thickets forming the marginal vegetation of the 
marsh Orthoptera were not very common, the only species taken there being 
Melanoplus differentialis and Melanoplus oboatipennis, both of which were 
only moderately common. In the open clover field surrounding the marsh 
the only species observed was J/elanoplus femur-rubrim. 
15. This was a small lateral ravine which opened into the valley of 
indian Creek close to where it empties into the Wabash. It was visited 
June 28. Orthoptera were very scarce at this time, but on a steep wooded 
slope where there was much bare ground with scattered growth of the 
woodland Panicum, P?. huachuca, 1 captured a male Melanoplis fasciatus. 
‘The woods here were denser than usual and were cool and shady with only 
few scattered openings where the direct rays of the sun reached the 
ground. The soil at this spot is mapped as Miami silt loam. 
16. This includes the east bank of the Wabash and the adjoining bot- 
toms about 24 miles southeast of Battle Ground examined August 30th. 
The river bank here slopes very gently and at the time of my visit was cov- 
ered next the river with a growth of sedge, apparently Scirpus americanus, 
and landward of this by Homalocenchrus oryzoides. Above this on higher 
ground was a fringe of woodland with a dense undergrowth of Makhien- 
bergia. Beyond this were the flat cultivated lands of the bottoms. At this 
point the bottoms are about a quarter of a mile wide. At their outer 
edge—the edge away from the river—they are characterized by the usual 
line of high bluffs forming the edge of the neighboring upland. At the base 
of the bluffs was the usual seepage zone, which at this place was repre- 
sented by an extensive marsh in which Homalocenchrus oryzoides tormed 
ihe buik of the vegetation. Bordering it were the accompanying thickets 
of tall composites. 
The Orthoptera of the river bank at this place were disappointingly 
scarce. The only species at all common was Orchelimum nigripes which 
wis observed only in the cut-grass. A single specimen of Neoconocephalus 
palustris was taken in the sedge, but it had apparently strayed there from 
the cut-grass areas. No other species were noted on the river margins 
On the cultivated parts of the flood plain there were in several places rank
