At 4:31, No. 58 came back again, but not straight to the nest. 
She flew around from bush to bush in the vicinity, hanging from 
the twigs a minute at a time. Once she allowed me to come close 
enough to see distinctly that she was hanging upside down by her 
first and third pairs of legs, while with her middle pair she clasped a 
small bug, holding it by its interior end, head directed forward. 
After thus ‘^hanging around” for some minutes, she returned to the 
nest after her wonted manner. 
The next two days, Sept. 4th and 5th, were also spent in pro- 
curing provisions. The nights were not spent in the nest ; this was 
carefully closed at the last departure in the afternoon and the night 
was spent in other parts. I have seen the species late in the eve- 
ning dig a shallow nest and crawl into it for the night, closing it 
from the inside. 
At 5 :33 the wasp brought in her last bug. It was fourteen min- 
utes this time before she again made her appearance for the reason 
that she was now making the permanent closure of the nest after 
the manner of Bembex belfragei. After the burrow was filled with 
sand she scratched the sand all around the nest, even climbing to 
the top of the bank three inches above pulling down the sand. In 
this way all trace of the nest was obliterated. I immediately dug 
up the nest. Eighteen bugs were found in the lower, somewhat 
dilated end. There was no wasp egg or larva but three large 
fly-maggots were busy eating the store of food. 
Specimen No. 48 began digging her nest at 9 :15 a. m., Aug. 31st 
and finished at 10 :55. She, too, made an extensive locality study 
among the weeds in the vicinity, returning to the nest several times 
before flying away. She stored five bugs the first day. A parasitic 
fly, Masiena sp kept hovering around the nest and twice, when the 
wasp returned with a bug, the fly flew up four feet or more to meet 
the wasp and as the latter descended, gradually the fly flew back- 
ward ahead of the wasp, maintaining a distance of about three 
inches from her until the two reached the nest. After this was 
opened and the wasp had entered, the fly went in also and came out 
just ahead of the wasp. In the nest I found five bugs, one of which 
held the egg which was attached exactly like the egg of B. belfragei. 
No. 50 began digging her nest at 9 :30, only five feet from that of 
No. 48, also on the same day. She stored her bugs in the afternoon 
of September 2nd. As the wasp had not visited the nest after 11 :20 
Sept. 2nd, I opened the nest at 8 :00 a. m. Sept. 3rd and found a 
large larva among ten bugs, the viscera of most of which had 
already been eaten away. The nest is shown in Eig. 19. It was a
