for at least an hour, which was as long as I watched 
her. No workers assaulted the cell, but the queen 
was so busy at it, walking round and round it as 
she rapidly polished it, that they could not have 
succeeded had they tried. 
This cell was standing next morning. 5 
As time went on more eggs were laid, and a large 
number of ves¢a/zs males and females developed ; 
but although the nest contained many fertile workers, 
not one éervestvis male was produced. 
A CRIPPLED TERRESTRIS QUEEN. 
On May 4, 1911, I caught two ¢errestris queens, 
A and &, and kept them together in darkness. 
Their quarters, like those of all my other captive 
queens, consisted of a nest starting-box communicat- 
ing by means of a small hole with a vestibule or outer 
box. On the floor of the nest-box I placed a disc of 
sacking, to which were firmly fastened by melted 
bees-wax two deep cells of bees-wax, which I filled 
twice a-day with a mixture of honey and water ; | 
also fastened to the sacking a shallow cup made of 
old /afidarius wax containing a lump of pollen. 
A had her left hind tibia slightly paralysed, the 
result of an injury sustained before she was caught. 
May 8, 9.0 p.m. A formed a cell in the place 
that the pollen lump, which was now consumed, 
had occupied, and she laid an egg in it. JB's 
tongue was seen to be injured, she could not fold it 
up properly.
