$:18. Explored top. Cleaned front legs and antenne. 
8:19. . Steod still. Occasional movement of head, antenne or abdomen. 
8:20. Same as 8:19. 
:21. Began to explore again, becoming quite lively. Antenne constantly waving. 
:22. Same as 8:21, but extended its travels to the under (cell) side of the nest. 
8:23. Left the nest entirely and began to walk around the surface of the desk. 
8:24. Started to climb a bottle that was some six inches from the nest. Antenne stil] 
waving. : 
$:25. On the neck of the bottle, two inches above the surface of the desk. Cleaned 
front legs and antenne. 
:26. Quiet except that it spread its wings cnce. 
Still on neck of bottle. Moved its head and antenne back and forth. 
Slight change in position. Antenne were still waving. Rubbed its wings, spread 
them, and then rubbed them again. 
:29. Rubbed its hind legs together vigorously. 
¥:30. Spread wings once, then rubbed them and the abdomen with the hind legs. 
Rubbed the hind legs together, and finally rubbed the right wings vigorously. 
$:31. Moved around some, occasionally stopping to rub the right wings. 
$:32. Explored the neck of the bottle. 
8:33. Same as 8:32. Cleaned antenne. 
$:34. Same as 8:33. 
8:35. Stood still but continued to clean antenne and front legs. 
8:36. Climbed up and explored the cork of the bottle. 
8:37-8:40. Stood still on the cork, occasionally moving its jaws. 
At 8:40 the nest was placed against the cork and the wasp immediately crawled 
cnto it, but seemed restless. As the nest has a faint, but distinct, odor of honey, it was 
probably attracted to it through the sense of smell. 
The next morning the specimen was nowhere in sight, but forty-eight hours later it 
fell out of a loose-leaf binder that had been lying on the desk. It seemed to be as 
active as when seen two days before. Some time during the second night after the 
>ppearance of the first specimen, that is, when it was some thirty hours old, a second 
individual emerged. This one was discovered on a pile of books two feet from the 
nest where it had evidently crawled scon after emerging. 
As soon as the first specimen was rediscovered, that is, when it was sixty hours 
old, the second wasp then being thirty hours old, the two were placed en the nest, and 
this in turn was placed on a book. ‘They both started on tours of observation, and 
every time they came in contact with each other they made sudden starts and jumps 
to avoid an evidently startling new object, meanwhile violently waving their antennz 
and often cleaning these organs after such contact. Dr. Enteman says, “All wasps 
possess the instinct of fear. This * * * is readily overcome by the frequent ap- 
pearance of the awe-inspiring object.” This is true, because they were evidently on 
familiar terms with each other in half an hour, and paid very little attention to the 
frequent meetings which before had apparently distressed them. They wandered 
freely over their nest and the top surface of the book on which it was placd, but did 
not attempt to climb off the latter. 
At 12 o'clock, four hours later, a third wasp had appeared, and none of the speci- 
mens seemed to be disturbed by the presence of the others. When the nest was first 
picked up, one cell containing a well formed pupa was uncapped. This specimen was 
then alive, but it may have been dead at the time of this observation. In either case, 
it had been dragged out of its cell, decapitated, and the front legs torn off. No trace 
of the head was found, but the body and legs were on the book about one inch from 
the nest. Whether this act was connected with the hunger of the wasps themselves or
