3. Diameter of lateral ocellus longer than ocell-ocular line; malar space shorter than 



basal w-idth of mandible; ocellar and occipital black ppofa much reduced; 

 thorax largely pale yello^\', the mesoscutum and propodeum marked u-ith 



bro'ATi Jlariceps, new tpecies. 



Diameter of lateral ocellus shorter than ocell-ocular line; malar space as long aa 

 basal width of mandible; ocellar and occipital black spots broadly confluent, 

 the former extending to base of antennae; thorax testaceous \vith black 

 markings above platynotae, new species. 



4. Diameter of posterior ocellus distinctly shorter than postocellar line; areola and 



petiolar area distinctly separated minor, new species. 



Diameter of posterior ocellus equal to or greater than postocellar line, at least not 

 distinctly shorter; areola and petiolar area confluent or only indistinctly 

 separated 5. 



5. Diameter of posterior ocellus equal to postocellar line; petiole subequal in length 



to dorsal length of propodeum facib's (Cresson). 



Diameter of posterior ocellus greater than postocellar line; petiole distinctly 

 shorter than dorsal length of propodeum breripetiolus, new species. 



6. Hind and middle coxae throughout and front coxae broadly black; orbital ring 



A'ery narrow behind the eyes and broadly interrupted above and below; 

 face black medially, this mark confluent with the black of malar space. 



brevicauda, new species. 



Hind and middle coxae at most black at base, front coxae entirely yellow; orbital 



ring broad and complete or at most narrowly interrupted behind the eye; 



face entirely yellow or if marked with black the malar space is j^ellow 7. 



7. St:gma nearly half as wide as long; wings milky hyaline with veins except stigma 



and costa very pale cookii Weed . 



Stigma barely one-thii'd as ^vide as long; wings clear hyaline with dark veins. . 8. 



8. Eyes and ocelli not large, former hardly longer than width of face, latter subequal 



to ocell-ocular line; malar space subequal to basal width of mandible; 

 pronotum and mesoscutum laterally yellow marked . . .epagoges, new species. 

 Eyes and ocelli very large, former much longer than width of face, latter much 

 broader than length of ocell-ocular line; malar space very short; pronotum 

 and mesoscutum black except a small, obscurely bro%vni8h spot in front of 

 tegula forbcsii Weed. 



9. All coxae pale, the hind pair not at all black or blackish at base 10. 



At least the hind coxae black or blackish at base 12. 



10. Eyes and ocelli not especially large, malar space and ocell-ocular line not espe- 



cially reduced, face broad tetralophae, new species. 



Eyes and ocelli very large, malar space and ocell-ocular line much reduced, face 

 narrow 11. 



11. Thorax and propodeum, especially the latter more or less black . . .reliniae Cresson. 

 Thorax and propodeum entirely testaceous delicatus (Cresson). 



12. Small species with abdomen black throughout or obscurely reddish in middle, 



tergjtes never apically yellow 13. 



Larger species wiih first two tergites (occasionally only first one) black, the 

 others red or piceous, sometimes more or less yellow or black or both, occa- 

 sionally almost entirely black but with apical tergites narrowly yellowish . . 14 



13. Clypeus rather narrow, much more than half as long as wide, and weakly separated 



from face; posterior ocellus narrower than ocell-ocular line; tergites 3 and 4 

 piceous or reddish; orbital ring M-ith a broad interruption opposite ocelli, 

 the yellow color not touching the lateral ocellus. .mordelUstcnae, new species. 

 Clypeus broad, distinctly less than half as long as \vide, and with suture deeply 

 impressed; posterior ocellus fully as wide as ocell-ocular line; all tergites 

 entirely black; orbital ring extended triangularly and touching the lateral 

 ocellus, interrupted on each side of the triangular spot 



incompletua (Provanchcr).
