5. Frontal horn black 2. capitator (Fabricius). 



Frontal horn white 3. albiniclavus, new species. 



6. Head, pronotum, and mesoscutum black, without white markings. 



5. tubulifera (Viereck). 



Head with face, clypeus, frontal orbits, and apex of horn white; entire 



thorax red 6. buscki, new species. 



7. Apical carina of propodeum wanting, apophyses long or tuberculiform, 



rarely carinate 8. 



Apical carina complete, angled sharply forward in middle, apophyses in 

 the form of high carinate elevations (fig. 4) 48. 



8. Apophyses of normal form ; mesoscutum without tubercles above tegulae 9. 



Apophyses in the form of high transverse carinae (fig. 5), the propodeum 



longitudinally sulcata from basal carina to apex ; mesocutum with a white 

 tubercle above each tegula 48. carinispinis, new species. 



9. Propodeum and metapk^urum not rugose, or jf so apophyses are long; 



frontal horn usually spiniform or conical, rarely constricted near base_10. 

 Propodeum and metapleurum coarsely rugose, apophyses low rounded tuber- 

 cles; frontal horn bulbous (fig. 6) ; areolet very small. 



47. bulbosus, new species. 



10. Nervellus broken, discoidella distinct ; areolet much longer than broad with 



recurrent at or near apex ; mesoscutum immaculate or with two white 



lines on disk 11. 



Nervellus unbroken, discoidella entirely wanting ; areolet nearly as broad 

 as long, with recurrent not far beyond middle; mesoscutum with a median 

 white spot 46. infractus, new species. 



11. Clypeus more or less distinctly iuflexed ; scutellum high and more or less 



compressed ; aiwphyses usually elongate, in male sometimes low but not 



so smoothly rounded; first segment at most weakly decurved 12, 



Olypeus and scutellum strongly convex but clypeus (tig. 7) not inflexed at 

 apex and scutellum not compressed from sides; apophyses low rounded 

 tubercles; first abdominal segment strongly decurved (fig. 8); ovipositor 

 more than half as long as abdomen 45. rufipleuris Szepligeti. 



12. Thorax entirely ferruginous 13. 



Thorax more or less black, at least meso.scutum black or piceous 25. 



13. Abdomen entirely ferruginous 14. 



Abdomen black and white, at most with first tergite largely red 18. 



14. Inner and superior orbits broadly white 7. ornatifrons, new species. 



Orbits not at all white 15. 



15. Head entirely black 8. inornatus, new species. 



Head with a least clypeus pale or reddish 16. 



16. Clypeus and mandibles reddish 9. minutus, new species. 



Clypeus and mandibles white 17. 



17. Occipital carina very prominent below and separated from hypostomal carina 



by a deep groove 10. boliviensis, new species. 



Occipital carina fading out some distance from hypostomal carina but not 

 prominent at lower end, the space between it and hypostomal carina shal- 

 low 11- areolatus, new species. 



18. Occipital carina abruptly interrupted below, its lower end very prominent 



and separated from hypostomal carina by a deep, broad furrow 19. 



Occipital carina reaching hypostomal carina or if not its lower end is not 

 prominent or there is only a small notch next to the hypostomal 

 carina 22. 



19. Face black 20. 



Face white 21.
