planted plats themselves. Once two individuals of Neonocephalus rolmstus 

 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 small 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 (Phleum pratense), while the remaining half had at some time or 

 other been used as a dumping place for manure or other refuse and was 

 now occupied by a rich growth of Elymus virginicus, with which were in- 

 termixed some areas of Browns (ciMatus?) and a few clumps of a taller 

 species of Elymus, probably canadensis. On one side near a fence row was 

 a rank growth of sumac (species not determined). In another part of the 

 field at one end of the Elymus formation in a shallow gully was a rank 

 growth of green foxtail (Chaetochlou riridis). 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. Melanoplus femur-rubrum, Melanoplus atianis, Encop- 

 olophus sordidus and Concocephalus strict us were here abundant, while 

 ooth isyrbula admirabilis and Arphia xanihoptera were of frequent occur- 

 rence. Early iu July Melanoplus femoratus was fairly common in this 

 tract, but it soon ceased to be an evident component of the fauna. Two 

 55 of OrpJiuletlla speciosa were taken on July 22; repeated search failed to 

 reveal any additional specimens of this apparently very rare species. A 

 single male Scudderia texensis was also catured here the same date. In 

 the Elymus patch a solitaiy male Conoceplialus fasciatus was taken also on 

 the same date ; while much later in the season — September 13 — a sma 1 

 colony of Conoceplialus nemoralis was found in a place where the Elymus 

 was encroached upon by the sumac thickets. Melanoplus different iaJ is was 

 also frequent here. Outside of these three species, the forms in the 

 Elymus area were the same as those in the timothy with the exception of 

 Arphia xaiithoptera which appeared to be limited to the latter. The fox- 

 tail growth formed the favorite habitat of Orchelimum rule/are. The sain .■ 

 grass also yielded a female of Stenobothrus curtipenms.
