Metapleurum black, rarely ferruginous, in which case the hind basitarsus is 



not entirely white; seventh tergite usually with a white spot and usually 



more or less black; front wing 2.8 to 7.2 mm. long 4 



4. Face white medially and laterally or entirely white, the white median mark (when 



discrete) joined to the clypeus, which is also white; mesopleurum just below

and sides of face white; second segment of hind tarsus entirely white or 

 sometimes partly brownish; hind coxa black or fuscous; propodeum entirely 



black 8. cimbcivorus (Cushman) 



Wrinkling on mesopleurum just below the tegula irregular or mostly vertical, 

 rarely mostly longitudinal; coloration not entirely as described for cimb- 

 civorus 6 



6. Clypeus moderately convex, black, brown, fulvous, or sometimes white; face 



a little narrower, medially rather convex and weakly punctate; hind basitar-

2. Profile of upper margin of ovipositor tip almost straight between the nodus 



and apex (figs. 327,g,h) ; basal ridges on tip of lower valve of ovipositor 

 vertical (figs. 327,g,h); wrinkling of mesopleurum just below subtegular 

 ridge with a tendency to be longitudinal rather than vertical or irregular; 



parasites of Clavellariidae 3
