The first colony (82-02-04-1) contained a single comb of 147 
uncapped cells, 24 of which contained early-instar larvae and 48 
with eggs. These were concentrated in the center of the comb. No 
sign of cell re-use was present; the nest appeared to be quite young. 
Twenty-six adults were captured, six of which proved to be queens. 
Among the 20 workers, one had developing oocytes in the ovarioles, 
but these were still smaller than the accompanying trophocyte 
masses. Measurements consisted of maximum apical width of meta- 
somal tergum I and length of this segment taken from the ligament 
base to the apex, as well as length of the discal cell. The tergal 
measurements were not significantly correlated with each other (all 
N=26; r=.303, Pearson product-moment correlation), but were 
correlated with length of the discal cell (r=.482, p<.05 for tergal 
width; r =.488, p <.01 for length). Hamulus number was not signifi- 
cantly correlated with any measurement (r=.063 for tergal width, 
.076 for length, and .157 for discal cell length). Only discal cell 
length was significantly correlated, negatively, with ovariole index
