1. A sharp transverse carina between the antennae; elypeus coarsely trans- 



versely rugose - (Toryna) vespoides (Cresson). 



No carina between the antennae; elypeus not rugose, but chagreened or 

 punctate (2) 



2. Angles of propodeum niucronate or dentate (3) 



Angles of propodeum rounded, not dentate 



(Pseudomasaris) marginalis (Cresson) . 



3. Middle tibia, seen from above, inflated beyond the middle; middle femur 



with its inner posterior margin carinate and more or less sinuate; 



color black and bright yellow (Cotyledon) edwardsii (Cresson). 



Middle tibia, seen from above, not inflated (4) 



4. Middle femur scarcely flattened and not ridged beneath; color of the 



body partly tavray, ferruginous or rufous, or at least the legs beyond 

 the coxae all tawny except sometimes for a yellow spot on the femora-(5) 

 Middle femur flattened beneath, its anterior lower border marked by a 

 ridge; color black and saffron or lemon yellow, without rufous or 

 tawny markings ; (10) 



5. Clypeus very coarsely and densely punctate, almost rugose; tawny, in- 



verted V-shaped spot on front, mesonotum except next to the tegulae, 

 mesoventer, sometimes part of pleura and lower part of propodeum, 

 mesal spot on dorsal segments 1, 2, and 3, and a mesally dilated basal 

 border on dorsal segments 4 and 5, and a narrow basal border on 



ventral segments 4, 5, and 6, black 



(Pseudomasaris) occidentalis (Cresson). 



Clypeus weakly and shallowly punctate, sometimes punctulate with scat- 

 tered coarser punctures; black, with yellow and usually with rufous 

 marking (Holopticus) (6) 



6. Middle of mesonotum just in front of seutellum very densely and finely 



granular-punctate; second dorsal segment closely, rather finely and 



evenly punctate, matte (7) 



Middle of mesonotum in front of seutellum coarsely, confluently, almost 

 rugosely punctate, this area of the mesonotum strongly depressed; 

 second ventral segment with separated coarser punctures, the abdomen 

 and pronotum more or less polished and shining; color black, saffron 

 yellow and red, with a strong preponderance of yellow on the abdomen 

 phaceliae Eohwer 



7. Mesonotum just in front of seutellum with a strongly depressed area, not 



reaching the lateral groove of either side, this area finely granular, 

 while the raised area at the sides and anteriorly is more coarsely and 

 sparsely but still densely punctate; front always with a triangular 



white area, legs beyond coxae entirely reddish (8) 



Mesonotum in front of seutellum flat, but without a median depressed 

 area, the sides and anteriorly finely and densely punctate, but not 

 granular as in the middle just before the seutellum; front usually 

 without a white spot (9) 



8. Thorax and abdomen with a large amount of red
