PiPIZA is nearly related to Psilota and also to Milesian but is 

 at once distinguished by the profile, the clypeus being plain or 

 rounded, whereas in the cognate groups it projects, making 

 the face concave. The Pipizce delight in sunshine, and not 

 only frequent flowers, but often settle on the leaves of laurels, 

 hazels, brambles, &c. The following British species are thus 

 divided : 



A. Transverse terminal nervtire oblique (9). 

 a. Abdomen with yellow bands or spots.
