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 tbe dryer 

 groves of the adjoining upland. On September 13 the fauna had much the 

 same 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 Chlcealtis conspersa had not been taken on tbe 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 Chlcealtis 

 conspersa only a single male was taken along the edge of the cat-tail bog 

 close to tbe spot where the Truxalis was taken on the earlier date. Besides 

 tbese other species taken or observed on September 9 were Dichromorpha 

 viridis (10), Melanoplus obovatipennis, M. differentialis, Scudderia f ar- 

 eata (10), Orchelimum, vulgare, Conocephalus brevipennis and C. nigro- 

 pleurum. 



3. The Purdue Experimental Farm in West Lafayette 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 tbe land is unfilled, as along 

 fences and the borders of paths, there is a firm blue-grass sod in which 

 scattered patches of clover (T. pratense) are frequent; also the usual 

 weeds, such as witch-grass' {Panieum capillare) , spreading panic-grass (P. 

 dichotomiflorum) , crab-grass (Echinochloa crus-galU) , foxtail (Chaeto- 

 chloa viridis, C. glanca) , Orchard grass {Daetylis glomeratus) and Eragros- 

 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 tbe neighboring plats. The 

 most abundant species here was naturally Melanoplus femur-rubrum ; 

 other common forms were Encoptolophus sordidios, Dissostcira Carolina, 

 Melanoplus atlanis r Orchelimum vulgare (specially in the taller grasses, 

 such as fox-tail, etc.) and Conocephalus st rictus, tbe 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, Chor- 

 tophaga viridifasciata, and Melanoplus differential is. Occasionally a spec- 

 imen of Schistocerca americana would be taken or observed in the rank 

 weedy growth bordering the experimental plats and in tbe more thickly
