and tibia reddish; middle femur and tibia reddish above, varying to 

 whitish beneath; hind tibia with subbasal fuscous annulus complete. 



Female: Front wing 4.5 to 8.5 mm. long; antenna with 21 to 24 

 segments; cheek about 0.35 times breadth of base of mandible; temple 

 strongly rounded and rather weakly receding; thorax moderately 

 stout; propodeum rather short and usually with short, rather weak, 

 dorsomedial carinae; sheath about as long as or a little longer than 

 abdomen; ovipositor with a distinct nodus. 



Black. Palpi usually tinged with fuscous; tegula and spot in hind 

 corner of pronotum whitish; stigma blackish; legs mostly red; hind 

 tibia and basal two or three segments of hind tarsus whitish with 

 fuscous annuli, the subbasal fuscous annulus on hind tibia complete 

 and often joined with the apical annulus by a narrow fuscous streak 

 beneath; pattern of hind tibia faintly repeated on front and middle 

 tibiae. 



This species may not prove to be distinct from buolianac (Ratze- 

 burg) of Europe. I have been unable to distinguish females, and 

 males appear to differ only in slight details in the structure of the 

 front femur. In the male of tecumseh the median swelling on the 

 underside of the femur that gives rise to the double emargination is 

 usually distinct only on the anterior margin of the femur, whereas in 

 buolianae it usually extends across the femur almost to the posterior 

 margin.
