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 Paroxrya hoosieri, the 
only place where I obtained this interesting species. With it were large 
numbers of Orchelimum nigripes, Conocephalus brevipennis and Cono- 
cephalus nigropleurum. In the marginal thickets were observed such 
forms as Melanoplus differentialis, Conocephalus fasciatus, Melanoplus 
scudderi 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 huachuca@ 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 whiie later in the season Melanplus scudderi and Mclanoplus 
luridus were common. 
ANNOTATED LIST OF SPECIES.! 
Diapheromera femorata Say. A single specimen, a male, taken in low 
woods on Burnett Creek near Battle Ground (2), August 9. 
Acrydium (Tettix) ornatus Say. Moderately frequent in spring on 
dry hillsides and in stubble fields on the upland near West Lafayette. 
Truxalis brevicornis (Linnzeus). 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, Cephalanthus occidentalis; 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 latifolia), sedges (species of 
Carer, Scirpus atrovirens), NSagittaria, Panicularia nervata, Helianthus 
spp. Species apparently quite scarce as no other examples were seen. 
Syrbula admirabilis (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 Innds; less fre-
