growths of common weeds and in these Melanoplus femur-rubrum and 

 Melanoplus differentialis were abundant. The best collecting from the 

 standpoint of variety was afforded by the marsh at the base of the bluffs. 

 Here in the cut-grass I found considerable numbers of Pa'roxya hoosieri, the 

 only place where I obtained this interesting species. With it were large 

 numbers of Orchelimum nigripes, Conocephalus brevipennis and Cono- 

 ccphalus nigropleurum. In the marginal thickets were observed such 

 forms as Melanoplus differentialis, Conocephalus fasciatus, Melanoplus 

 soudderi and Melanoplus obovatipennis. 



17. This was a small open groove on rather dry barren soil. It is 

 located on a gentle slope just above the Wabash bottoms on the west side 

 of the river about three miles southwest of West Lafayette. The soil is 

 Sioux sandy loam. In the groove at this point it supports a rather weak 

 growth of blue grass. In the driest parts the blue grass is sparse and in 

 such places Panicum huaehucw becomes a noticeable constituent of the 

 herbaeous flora. The Orthoptera taken here were the usual species of dry 

 open woodland. In July and early August Spharagemon bolli was quite 

 frequent while later in the season Melanplus scnddeti and Melanoplus 

 Hindus were common. 



Annotated List of Species. 1 



Biapheromera femorata Say. A single specimen, a male, taken in low 

 woods on Burnett Creek near Battle Ground (2), August 9. 



Aery din m (Tettix) ornatus Say. Moderately frequent in spring on 

 dry hillsides and in stubble fields on the upland near West Lafayette. 



Truxalis brevicornis (Linnaeus). Two specimens; a female nymph 

 taken July 27 in upland deciduous woodland about one mile northwest of 

 West Lafayete (1) in a grassy tract a short distance from a bog domi- 

 nated by buttonbush, Gephalanthus occidcntalis; a mature male taken 

 August 9 in low woods along Burnett Creek (2) near Battle Ground at the 

 edge of a bog containing cat-tail (Typha lutifolia), sedges (species of 

 Carex, Scirpus atrovirens), Sagittaria, Panicularia nervata, Heliantlius 

 spp. Species apparently quite scarce as no other examples were seen. 



Syrbula admirabttis (Uhler). Of frequent occurrence in all relatively 

 dry grassy areas at higher levels and locally at least, where conditions are 

 suitable, not uncommon in bottom lands. The species is prevailingly cam- 

 pestral in its habitat, being especially fond of open grass lands ; less f re-
