1'. Head at most with narrow white markings; no white on gaster; 
apical margin of clypeus entire, not or scarcely produced

mesoscutum 3 
2'. Second gastric tergite smooth and polished with at most faint 
micro-reticulation; notaulus 0.3-0. 8 as long as mesoscutum, 
in most species no more than 0.5 as long 4 
3. Mesoscutum with very abundant, mostly subadjacent to conflu- 
ent, medium sized to large punctures; flagellum usually with 
a white band; head and mesosoma purple with blue reflec- 
tions; gaster mostly blue or blue-green; no golden sheen on 
thoracic pleura and propodeum 9. T. viridis (Brulle) 
3'. Mesoscutal punctures strong and dense only anteriorly on cen- 
tral lobe but elsewhere mostly sparse; flagellum dark; body 
blue or blue and purple, with golden reflections on thoracic 
pleura and propodeum 8. T. cleonis Viereck

mesoscutum; propodeum with moderately strong reticulate 
wrinkling; flagellum with white on more or less of segments 
4-8 l.T. escomeli (Brethes) 
4'. Clypeus low, gently convex to almost flat in profile; notaulus 
0.3-0. 5 the length of mesoscutum; propodeum with gross 
reticulate wrinkling; white on flagellar segments 1, 2 or 3-8, 
9, or 10 5 
5. Areolet asymmetric, apical abscissa of cubitus inserted unusually 
far dorsad; 1st flagellomere 3.2 as long as deep at apex; 
mesoscutum with numerous but mostly well separated punc- 
tures; propodeal cristae broad and strongly projecting sub- 
ligulate; sheathed portion of ovipositor 0.60 as long as fore

5'. Areolet not asymmetric, apical abscissa of cubitus in normal 
position; 1st flagellomere 3. 9-4. 2 as long as deep at apex; 
mesoscutum with punctures, at least on basal 0.5, dense and
