and Conocephalus attenuatus. In the pasture in which Tridens flava was a 

 common plant Si/rbula admirabilis and Conocephalus strictus were of fre- 

 quent occurrence along with larger numbers of the ubiquitous Melanoplus 

 femur-rubrum. Close to the border of the same field, where there were 

 some extensive patches of Elymus virginicus, several examples of Dichro- 

 morpha viridis were observed. 



7. This was a level tract of very open woodland located on top of 

 the bluff overlooking tbe bottom lands included in locality 6. The ground 

 here had been used for pasturing cattle and the herbaceous vegetation was 

 accordingly quite short and scanty. Orthoptera were scarce. Each Melan- 

 oplus atlanis and Melunophis femur- rub rum were frequent, while in one 

 place where there was considerable slope and a fair amount of scrub 

 growth a few examples of tipharagemon bolli were seen. Late in June 

 Atlanticus testaceus occurred in small numbers, several being captured one 

 night on low shrubs and tall weeds. 



S. This locality was a small open grove at tbe top of tbe highest line 

 of bluffs at the north end of a ravine situated nearly half way between 

 West Lafayette and the mouth of Indian Creek. The soil was the Miami 

 silt loam which in this exposed situation was quite dry and barren and had 

 a decided sandy appearance. Along a recently cut roadside I found at this 

 point a young specimen of the black-jack oak, the presence of which natur- 

 ally indicates the barren character of the location. Tbe soil here at the 

 time of my visit — August 24th — was formed of blue-grass sod with occa- 

 sional patches where the ground was bare or but sparsely covered with 

 vegetation. In such places the common woodland I'anicum, P. huachucw, 

 was frequent. In two or three places erosion had worn slight gulleys from 

 which most of the finer soil particles had been washed away leaving a very 

 hard and stony soil on which very little vegetation had as yet obtained a 

 foothold. These gulleys were the favorite habitats of the more geophilou> 

 Orthoptera such as Arphia xanthoptera, Spharagemon bolli and Dissosteira 

 Carolina. 



Only about a half hour was spent in collecting at this spot, during 

 which examples of the following species were t-iken or identified : Syr- 

 bula admirabilis, Arphia xanthoptera, both yellow-winged and orange- 

 winged types, Encoptolophus sordidus, Sphragemon bolli, Dissosteira Caro- 

 lina, Melanoplus femur-rubrum and Melanoplus luridus. 



9. This locality is about half a mile southeast of Battle Ground in a 

 region covered by Miami fine sand. 'Practically the whole country is under
