all or much of front side of front and middle femora, sometimes part 

 to all of front and middle tarsi, rarely front side of hind tarsi, rarely 

 anteroventral part of hind tibia except at base, apex of front and 

 middle coxae, apical 0.6 ± of first tergite, apical margin of second 

 tergite laterally, apicolateral corners or a narrow apical band on 

 third tergite, apical 0.25 of fourth tergite, apical 0.2 of fifth tergite, 

 usually the apical 0.15 of sixth tergite, genitalia, and apical part of 

 seventh and eighth sternites, white; flagellum light brown beneath, 

 darker apically; wings more or less infuscate. 



Female: Colored like the male, except that the facial shield has a 

 large, broadly oval, central black area, and the cheek, clypeus, 

 mouth parts, and genitalia are black. 



Metopius pinatorius Brulle, 1846, has been listed as a synonym of 

 M. pollinctorius, but a study of the type in Paris shows that they 

 are from Europe, rather than from "Carolina" as reported by Brulle, 

 and are the common European Metopius micratorius of authors, not 

 of Fabricius. 



In both sexes specimens from areas towards the Southeastern States 

 have the wings progressively darker and the apical white band on the 

 sixth tergite progressively narrower. In Austroriparian specimens the 

 wings are strongly infuscate and the apical band on the sixth tergite 

 very narrow or absent. In Canadian and Alleghanian specimens the 

 wings are subhyaline and the apical band on the sixth tergite as wide 

 as that of the fifth. These two coloration types intergrade in a gradual 

 cline that does not permit subspecific distinctions.
