Front wing 4.3 to 13.5 mm. long; body form slender or moderately 

 slender; frons unarmed; clypeus of moderate size, moderately convex, 

 its apex truncate or approximately so, without a median tooth; fla- 

 gellum rarely with a white band or stripe, which when present is 

 usually basad of the middle; mesoscutum rather strongly convex, 

 polished or subpolished, with moderately strong, coarse to fine punc- 

 tures that are usually dense; notaulus usually sharp, extending be- 

 yond center of mesoscutum except that in T. crassifemur it does not 

 quite reach the center; epomia nearly always present, moderately 

 long; pronotum with a weak submarginal groove above upper end of 

 epomia; propodeum usually rather short, both of its transverse carinae 

 usually sharp, complete, and rather close together, the apical carina 

 usually forming a moderately distinct sublateral crest; propodeal 

 spiracle elongate; areolet large, pentagonal, its sides weakly to strongly 

 convergent; ramellus present, usually well developed; nervulus op- 

 posite basal vein; mediella weakly arched, usually approximately 

 straight except near its base and apex; nervellus broken near its lower 

 end; first abdominal segment without a sublateral basal tooth, its 

 postpetiole rather strongly expanded, its spiracle far behind the mid- 

 dle; dorsolateral and ventrolateral longitudinal carinae usually com- 

 plete; median dorsal carinae of first tergite usually extending beyond 

 spiracle, usually prominent on basal part of postpetiole; second ter- 

 gite mat, in male with fine, moderately dense setiferous punctures, 

 in female the setiferous punctures also fine but usually very sparse 

 so that they are separated by about three times the length of the 

 hairs, but rarely in Nearctic species (as in luctuosus and moschafor), 

 the punctures separated by a little more than the length of the hairs 

 and in some exotic species even more closely spaced; tergite 7 without
