which abounded in the surrounding country, appeared to be scarce in this 
place as only a single individual was observed. In a relatively dry part of 
the woods, where the ground was slightly damp, but by no means wet, were 
observed in a few specimens of Dichromorpha viridis and a single male 
Spharagemon bolli, the latter doubtless a stray individual from the dryer 
eroves of the adjoining upland. On September 15 the fauna had much the 
stune character, but was evidently poorer in both individuals and species. 
Of the latter only nine were recorded and of these only two, Orchelimum 
nigripes and Chlealtis conspersa had not been taken on the earlier date. 
The former species is usually the most abundant of the bog “long-horned” 
grasshoppers, but at this place it was exceptionally scare. Of Chla@altis 
couspersa only a single male was taken along the edge of the cat-tail bog 
close to the spot where the Tri-ralis was taken on the earlier date. Besides 
these other species taken or observed on September 9 were Dichromorpha 
viridis (10), Melanoplus obovatipennis, M. differentialis, Scudderia fur- 
cata (10), Orchelimum vulgare, Conocephalus brevipennis and C. nigro- 
pleurum. 
3. The Purdue Experimental Farm in West Latayette is located on 
“Second bottom” land. The soil is the Sioux loam. Nearly all the land is 
under cultivation, the principal crops being corn, wheat, rye, oats, clover, 
cow-peas, alfalfa and soy beans. Where the land is untilled, as along 
fences and the borders of paths, there is a firm blue-grass sod in which 
seattered patches of clover (7. pratense) are frequent; also the usual 
weeds, such as witch-grass (Panicum capillare), spreading panic-grass (P. 
dichotomiflorum), crab-grass (Hehinochloa crus-galli), foxtail (Chaeto- 
chloa viridis, C. glanca), Orchard grass (Dactylis glomeratus) and Bragros- 
tis major and purshii. In the more fully cultivated portion the “home” 
of the Orthoptera was in this relatively undisturbed grassy sod, although - 
they spread from this in large numbers into the neighboring plats. The 
most abundant species here was haturally JWelanoplus femiur-rubrum ; 
other common forms were Hncoptolophus sordidus, Dissosteira carolina, 
Melanoplus atlanis, Orchelimum vulgare (specially in the taller grasses, 
such as fox-tail, etc.) and Conocephalus strictus, the latter very common in 
the denser areas of blue grass. Other species of frequent occurrence, but 
not so abundant as those just mentioned, were Syrbula admirabilis, Cho. - 
lophaga viridifasciata, and Melanoplus differentialis. Occasionally a spec- 
imen of Schistocerca americana would be taken or observed in the rank 
weedy growth bordering the experimental plats and in the more thickly
