GENERAL OBSERVATIONS. 



Named from oajxT], 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 Anthophorce, 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
