p'anted plats themselves. Once two individuals of Veonocephalus robustus 
crepitans were taken and another heard in the corn fields: both of those 
captured were taken on corn in the early evening. 
The most interesting collecting on the Purdue grounds, however, was 
done in a sinall waste lot not far from the Lake Erie and Western Rail- 
road. About half of this lot was occupied by a nearly pure growth of 
timothy (P?hlewmn pratense), while the remaining half had at some time or 
other been used as a dumping place for manure or other refuse and was 
how occupied by a rich growth of Llymus virgiricus, with which were in- 
termixed some areas of Bromus (ciliatus?) and a few clumps of a taller 
species of Elymus, probably canadensis. On one side hear a fence row was 
a rank growth of sumac (species not determiled). In another part of the 
field at one end of the Elymus formation in a shallow gully was a rank 
growth of green foxtail (Chaetochloa viridis). Collections were mad> 
here at intervals throughout the summer. ‘The species were much the 
same as those occurring in the cultivated areas, but in addition a number 
of species were taken which were absent or very rare in the latter. In 
this waste land most of the collecting was done in the timothy, which had 
recently been cut, a circumstance which made it relatively easy to capture 
he grasshoppers. J/elanoplus fenur-rubrum, Melanoplus atianis, Eneop- 
olophus sordidus and Concocephalus strictus were here abundant, while 
soth Syrbula admirabilis and Arphia ranthoptera were of frequent oceur- 
rence. Early in July MWelanoplus femoratus was fairly Common in this 
tract, but it soon ceased to be an evident component of the fauna. Two 
og of Orphuletiila speciosa were taken on July 22; repeated search failed to 
reveal any additional specimens of this apparentiy very rare species. A 
single male Scudderia terensis was also catured here the same date. In 
the Llymus patch a solitary male Conocephalus fasciatus was taken also on 
ihe same date; while much later in the season—September 13-—a sma ] 
colouy of Conocephalus nemoralis was found in a place where the Llymus 
was encroached upon by the sumac thickets. IMJelanoplus differentialis was 
also frequent here. Outside of these three species, the forms in the 
HLlymus area were the same as those in the timothy with the exception of 
Arphia xauthoptera which appeared to be limited to the latter. The fox- 
tail growth formed the favorite habitat of Orchelimum vulgare. The same 
grass also yielded a female of Stenobothrus curtipennis. 
A short distance west of this lot in the adjoining field, which had been
