. Rau concluded that the colony was about to 
swarm. 
The S. testacea colony was collected at night, when all the adults 
were presumably on the nest, and very few escaped during collection, 
so the 6,466 adults taken represent close to the total population of 
the colony at the time. However, due to the disruption caused when 
the nest fell, it is possible that the population before the fall was 
significantly greater. 
A sample of 1,626 wasps was examined and found to comprise 115 
males (7.1%) and 15 11 females (92.9%). During the day after 
the nest was collected one male and three females emerged from 
combs 3 and 4, and one male and 32 females emerged from combs 
8 and 9. This indicates that males are reared in both younger and 
older portions of the nest. During the four days following collection 
of the nest a total of 422 adults emerged from all combs, and of these 
20 (4.7%) were males and 402 (95-3%) were females. 
The fourteen species of Stelopolybia , all neotropical, fall into two 
subgenera, Angiopolybia and Gy?nnopolybia. The nests of two of 
the three species of subgenus Angiopolybia have been described (see
