This is a very local species, appearing about the middle of April ; 

 it has been found on Wimbledon Common and at "Weybridge, also 

 in aome abundance at Blundall, near Xorwich. It resembles A. 

 lapponica ; but if the abdomen of the female be viewed sidewavs, 

 the pubescence will be seen to form suberect bands, the base of the 



segments being naked.
