Front wing 3.4 to 6.2 mm. long in male, 4.5 to 6.5 mm. long in 

 female; head about 1.55 as wide as long; propodeum subpolished ; 

 second tergite mat and with distinct longitudinal rugulae in the 

 depressions. 



Black. Antenna brown, its lower half pale brown, toward the base 

 pale stramineous, the scape of male mostly dark brown; maxilla and 

 labium whitish; tegula white; coxae fulvous to black, the front and 

 middle coxae whitish apically; trochanters whitish or pale fulvous; 

 femora fulvous, the apex of hind femur broadly fuscous, and apex of 

 front femur pale fulvous; apex of middle femur pale fulvous or some- 

 times with a narrow weak infuscation; front tibia and tarsus light 

 fulvous; middle tibia and tarsus light fulvous, often both a little

infuscate at apex; hind tibia and tarsus white, the tibia with broad 

 apical and subbasal blackish bands and each tarsal segment fuscous 

 apically. Specimens from colder localities are likely to have the 

 coxae largely black while those from warmer localities have them 

 entirely fulvous. European specimens seem always to have the coxae 

 mostly black. 



We have compared two males from Ireland and two females from 

 Germany with American specimens of this species. The European 

 specimens seem to be identical with American specimens having black 

 coxae.
