envelope was brownish-gray and quite flexible. The paper consisted 
of fine whitish fibers and plant epidermal fragments. Some thicken- 
ing of the envelope had occurred, but was not uniform. The enve- 
lope for each comb appeared to be the result of a single construction 
effort, and was attached to the edge of the combs. The entrance was 
at the edge of the ventral surface, and more or less continuous with 
the entrances to each comb. 
There were three combs. The oldest, basal comb contained 113 
cells, of which 48 were capped and contained pupae. These were 
concentrated in the center of the comb. Many of the pupae were 
melanized, and three adults were emerging as the nest was collected. 
The cells around the periphery of the capped cells contained 1 1 
late-instar larvae. The second comb consisted of 163 cells, of which 
1 18 were capped and contained pupae and prepupae. In addition, 16 
uncapped cells contained late-instar larvae. The third comb had 232 
cells. There were 18 early-instar larvae scattered about the comb, 
and an indeterminate number of eggs at the bottom of many cells 
(the edges of the comb were crushed, but the cells did not appear to 
have eggs). 
The number of adults taken was 1 12; 2 escaped. Among the cap- 
tured wasps were 23 teneral individuals classified as ’’callow”. These 
were measured and dissected, but omitted from most of the statisti- 
cal analyses (all had filamentous ovarioles). The remainder con- 
sisted of 34 queens, 22 intermediates and 33 workers. Measurements 
included maximum width of metasomal tergum II in addition to 
length of the discal cell. Following Richards and Richards ( 195 1 ) for 
the species myersi, the number of individuals with reddening of the 
proximal part of the metasoma, and the degree of yellow coloring of 
the scutellum were recorded. 
Tergal width and discal cell length were significantly correlated 
(all N = 1 1 2, r =.27 1 , p <.0 1 ). Neither measure was correlated with 
hamulus number (r = — .046 for tergal width, .214 for discal cell 
length), although the alpha level was close to .05 for discal cell 
length. Discal cell length was significantly correlated with ovariole 
index (r=.309, p<.01), but tergal width (r=.080) and hamulus 
number (r =. 1 7 1 ) were not. No significant association of measure- 
ments with color pattern were found. When the three castes were 
compared by ANOVA, width of tergum II was not different 
(F = 1 .08, df = 88). Length of the discal cell was significantly differ-
