GENERAL OBSERVATIONS. 
Named from ooyL), sweet-scent, from some fancied idea 
of their possessing the property of emitting a sweet 
odour; but this, although it is the case with many of 
the bees,—for instance, with the genera Prosopis, Halic- 
tus, Nomada, some of the Anthophores, Saropoda, and 
the male Bombi and Apathi, —I have not noticed in any 
of this subsection, the Dasygasters, and therefore not 
in any of the present genus. It is possible that when 
richly laden with pollen, this may emit some smell, 
but I am not aware that any of the scent of flowers 
lies in the anthers or their pollen, although this in 
some cases has a spermatic odour pointing to its express 
function; but be this as it may, such is their name. 
These as a group are what are called the ( Mason Bees/ 
from the habit they have of agglutinating particles of
