202 THE HUMBLE-BEE Vil 
males in 18371 or in 1863,’ which of these dates is 
not clear, and his son a queen in 1864, near Deal, 
but no other captures have been recorded. The 
species occurs in Central Europe. In the mountains 
of Switzerland and Austria, a variety having the 
whole coat yellowish-grey with the exception of a 
black band across the middle of the thorax is to be 
found. 
Hoffer took three nests of the red-tailed form on 
the Geierkogel in Styria. They were all under the 
ground, and in two of them he noticed what he 
called “ pollen cylinders.” In one of the nests with 
about 300 cells there were twelve of these pollen 
cylinders. They always stood at the end of a group 
of cells, but as the nature of these cells is not ex- 
plained it is not clear whether the species is a pollen- 
storer or a pocket-maker. The convex hind tibiz 
of the male and the long cheeks indicate that it 
is probably a pocket-maker occupying an interme- 
diate position between the pollen-primers and the 
carder-bees.
