(r = — .443, p<.05), however, the trends were also negative for the 
other measurements (r = — .307 for tergal width, —.338 for length, 
and —.050 for hamulus number). Queens did not differ significantly 
from workers in tergal width, discal cell length or hamulus number 
(t = — 1 .883, —1.917, and 0.070, respectively). Queens had signifi- 
cantly shorter terga than workers when compared by a t-test 
(mean = 1 .47 mm versus 1 .52, t = -2.470, p < .03). 
The second colony (82-02-04-2) had a comb of 151 cells. Of 
these, 25 were capped, and some contained partly melanized pupae. 
There were also late-instar larvae in some uncapped cells; the 
number could not be ascertained due to damage to the nest, but was 
not greater than 12. Other cells were empty. No sign of cell re-use 
was present, and the occupied cells were irregularly arranged but 
mostly central. This colony was probably also producing its first 
brood. Forty-six adult wasps were taken, of which seven were 
queens and 39 workers. Of the latter, 1 1 had slightly developed 
oocytes, but the index was 0. The tergal width and length were 
significantly correlated, both with each other (all N = 46; r = .375, 
p<.01) and with length of the discal cell (r=.567, p<.01 for tergal 
width; r =.726, p <.01 for length). As in the previous colony, hamu- 
lus number was not significantly correlated with the other mea- 
surements. No measurements were correlated with ovariole index 
(r=.026 for tergal width, —.032 for tergal length, —.219 for discal 
cell, and —.234 for hamulus number). Queens did not differ signifi- 
cantly from workers by any measure (t = 0.277 for tergal width, 
— 0.168 for tergal length, —1.495 for discal cell length, and —1.356 
for hamulus number). 
When the morphometric data for each colony were pooled, signif- 
icant correlations were found between all measurements, but not 
hamulus number. When further examined, the colonies differed sig- 
nificantly in tergal width, with colony 2 having workers with nar- 
rower terga (mean = 0.73 mm versus 0.76; t = -3.353, p <.002). No 
correlation with ovariole index occurred in the pooled data, but all 
trends were negative. Summing up, it appears that queens are 
slightly smaller than workers but the differences are not generally 
significant in these young colonies. 
Richards and Richards (1951) reported significant differences 
between queens and workers in hamulus number in this species, and 
this result has been widely cited (e.g. Richards, 1978; Jeanne, 1980).
