These bees are all solitary, and consist of male and female indivi- 
duals alone. The females collect pollen, not only with the hind feet 
but with other haired parts of their body; they dig under ground 
and place by their egg a provision of pollen and honey. Others, 
not formed for gathering pollen, lay their eggs in the nests of other 
bees. 
Andrena Fasr. Median division of ligula acuminate at the 
apex, lanceolate or hastate (triangular, auriculate on each side).
