THE HOME OF THE BEES. 603 
rather thick behind, but in front tapers slowly towards 
the head, which is of moderate size. Its body is some- 
what tuberculated, the tubercle aiding the grub in mov- 
ing about its cell. Its length is nearly one-half (.40) of 
an inch. On the pupa are four quite distinct conical 
tubercles forming a transverse line just in front of the 
ocelli; and there are also two larger, longer tubercles 
on the outer side of each of which an ocellus is situated. 
Figure 3 represents the pupa seen from beneath. 
Search was made on July 16th, when the ground was 
hard as stone for six inches in depth, below which the soil 
was soft and fine, and over twenty cells were dug out. 
‘ The upper cells contained nearly mature pupe, and the 
lower ones larvee of various sizes, the smallest being 
hardly distinguishable by the naked eye. Each of these 
small larvee was in a cell by itself, and situated upon a 
lump of pollen, which was the size and shape of a pea, 
and was found to lessen in size as the larva grew larger. 
These young were probably the offspring of several 
females, as four mature bees were found in the hole.” 
The larva of an English species hatches in ten days after 
the eggs are laid. ; 
Another brood of bees appeared the middle of Septem- 
ber, as on the ninth of that month (1864) Mr. Emerton 
found several holes of the same species of bee made in a 
hard gravel road near the turnpike. When opened, they 
were found to contain several bees with their young. 
September 2d, of this year, the same kind of bee was 
found in holes, and just ready to leave the cell. It is 
probable that these bees winter over. 
We have incidentally noticed the presence in the nests 
of Andrena and Halictus of a stranger bee, clad in gay, 
fantastic hues, which lives a parasitic life on its hosts.
