The Ecology of a Sheltered Clay Bank 215 
Ischnoptera pennsylvanica De Geer. An egg-case of 
this roach was found in one of the old bee tunnels. Just 
what would have been the chances of survival of the 
young if they had hatched, we can only surmise. An 
adult was also found hiding in a crevice on September 6. 
Locust nymph. This visitor was found as prey of the 
stick-bug, mesa brevipennis. 
Nemobius carolinus Scud. [A. N. Caudell]. One dead 
individual on the bank, September 7, 1917. 
Melanoplus femur-rubrum. One resting here Septem- 
ber 7, 1917. 
Tettigidea lateralis var. polymorpha Burm. [A. N. 
Caudell]. On October 3, 1917, several locusts of this 
Species were on the clay bank, probably attracted to the 
spot for shelter from the cold. One was in the web of 
Steatida borealis Htz., where a battle occurred between 
the plucky little spider and the big locust. 
Hapithus agitator Uhler. [A. N. Caudell]. A male 
visitor of this species fell prey to a spider, Phidippus 
tripunctatus [J. H. Emerton] on September 6, 1919. 
Hemiptera. 
Pselliopus cinctus Fab. [H. E. Gibson]. This bug was 
found in a spider’s web on September 12. 
Anasa tristis De Geer. While this bug was seldom 
seen at the bank during the summer, on October 3, a 
dozen adults were found quietly at rest among the rub- 
bish. Each year they appeared there late in the autumn. 
These bugs hibernate as adults, and had come to 
the bank seeking crevices in which to spend the winter. 
They probably appeared upon the scene too late to in- 
fluence the lives of others. On one occasion (May 20) a 
young spider, Phidippus sp. [J. H. Emerton], was seen 
feeding on one of these bugs.
