somewhat younger looking cocoons, most of which were 
full or partially full of honey, although many had only a 
little honey in the bottom. Most of the cocoons were ar- 
ranged in clusters of 7 to 11, each cluster representing a 
group of young that developed in a single cell. No cocoons 
large enough to have produced queens were present. 
Most pollen pots were made entirely of wax, which like 
other wax in the nest was soft and black. These pollen 
pots were up to 18 mm. in diameter and 32 mm. high. 
Some were empty, others full or partly so. Pollen was also 
stored in a very few cocoons, and in one or two pollen pots 
consisting of cocoons lengthened and enlarged with wax. 
Cells containing eggs were small, but ranged up to 31 
mm. in diameter when the larvae were mature. Several 
cells contained larvae spinning cocoons and one single larva 
had pupated. 
Remarkably few cocoons contained eggs and larvae, 
suggesting that reproduction was at a low ebb. This was 
likely due to the fact that we dug this nest just after the 
end of the dry season which had been long and intense. 
The following is a tabulation of the nest contents:

males

workers 
800 
pupae 
1 
mature larvae 
70 
medium sized larvae 
14 
small larvae 
18 
larvae of unrecorded size 
approx. 24

804 
cocoons with honey 
1227 
large pollen pots with pollen 
7 
small pollen pots with pollen 
16 
empty pollen pots

From the above tabulation it is evident that the queen 
must have produced 2183 offspring, of which 2031 had 
reached maturity before the nest was dug, and of which 
at least 800 survived until that time. This appears to be
