12: 13: 10 began to chxse the nest while still part way in the 
gallery scratching considerable quantities of material into the 
nest. She finally closed by taking material from around the nest, 
occasionally stamping it down with her abdomen. This she 
continued until a perfectly smooth surface was presented. 
l>elieving this careful closing to indicate the completion of the 
nest, the wasp was caught as she was flying away at 12: 18. 
As far as could be determined the entrance was but slightly 
narrower than the gallery. Cell i was 2 cm. lateral to cell 2, 
which again occupied the same plane as the entrance. A to B, 
8 cm. Rather loosely packed with sand. C to D, 2 cni. also 
])acked. 
Ckll T. 1.3 cm. long and 0.8 cm. in diameter. Regularly 
oval; 12 leaf hoppers. The egg was placed on the right side 
of the thorax parallel with the edge of the wing, but starting 
slightly posterior to the neck of the hopper. 
CiiLL 2. Seven hoppers and an egg which showed beginning 
larval segmentation. Placed on the right side of the thorax of 
the hopper as in cell i. 
The Xysson egg was not found.
