This is a very local species. It appears about the end of April 

 or the beginning of May. Mr. Kirby discovered it at Somersham, 

 near Ipswich. It has been found subsequently at Darenth Wood ; 

 and near Liverpool Mr. George Waterhouse took it in abundance, 

 finding its nests and breeding the sexes. He has published an in- 

 teresting account of its economy in the second volume of the ' Zoolo- 

 gist.' Near Bristol it has been observed frequenting the ground-ivy 

 (Glechoma hederacea) ; other localities known are Eastbourne and the 

 neighbourhood of Exeter. The male placed by Mr. Kirby in his col- 

 lection as belonging to this species is that of Osmia fulviventris.
