inward and ventral-side-upward or, less commonly, dorsal-side- 
upward or on the side. The egg-bearing beetle was located at the 
back end of the cell and was placed venter-up or pressed obliquely 
against the wall. 
In several nests, cells contained fresh or moldy prey but no egg, 
larva, or parasites. In three cases, abandoned prey were found 
buried in the sand plug which sealed off a fully-provisioned cell. 
Four beetles were entombed in single file in the loose sand in front 
of a cell containing six prey and an egg. The elytra of one beetle 
served as a wall-like barrier to the cell. 
Egg and Immature Stages. The curved, hyaline egg, 1.5-mm-long, 
was attached by the cephalic end to the anterolateral mesosternum 
near one of the procoxae (Fig. 3). It extended transversely but 
somewhat obliquely across the mesosternum, the free end lying above 
one of the anterolateral corners of the metasternum. Several mature 
larvae were reared and are described later in this paper. The brown, 
ellipsoidal cocoons averaged 2.5 X 5.5 mm and consisted of silk, 
saliva, and sand grains (Fig. 4). The uneaten prey fragments were 
not embedded in the cocoon but were pushed to one end of the 
cell by the larva. 
Nest Repossession and Renovation. During 19-28 August 1970, 
several females were provisioning nests at Chittenango but no males 
were seen. Other females were observed searching in holes and 
crevices rather than bringing in prey. Two of the wasps persisted 
in entering, backing out of, hovering in front of, and reentering 
certain burrows. Providing an appropriate site is found, such wasps 
may repossess and add to nests used earlier in the season by other 
females. In fact, nest 3 (Fig. 2c) with recently-captured beetles 
in the burrow also contained a dead memorialis female sealed off 
by loose sand at the end of the main burrow. Cells 1 - 1 3 housing 
cocoons or nearly mature larvae were probably made by the first 
female before she died, whereas cells 14-20 with recently-captured 
prey and eggs were probably made by the new occupant. In another 
nest, containing mostly old cells, a dead memorialis female was 
found deep in the burrow but she was not sealed off with sand. 
This nest, now being occupied by another female, held some 
recently completed cells and three beetles in burrow storage. 
Description of the Mature Larva 
Six mature larvae from Chittenango which were preserved in 
Kahle’s solution and later transferred to 70% alcohol were utilized 
in the following description. None of the larvae had begun to spin
