This might be a double definition.

'colonial' is the first definition.

'hairstyle?' is the second definition.
(beehive is a kind of hairstyle)

Can you help me to learn more?

(Other definitions for beehive that I've seen before include "Source of combs" , "where workers gather" , "place buzzing with activity?" , "Site of industry" , "(Busy) honey factory" .)
