Thorax and abdomen without red marking 



texanus neomexicanus Rohwer. 



9. Front without a median white triangle; knees white; three basal ab- 

 dominal segments with their ground color dorsally mostly red 



basirufus Rohwer. 



Front with a median white triangle; legs beyond coxae entirely rufous; 



two basal segments of abdomen with ground color partly red 



- maculifrons (Fox). 



10. Seen from behind, the middle tibia strongly contracted near its base; 

 cephalic margin of cell R^+a less than one-half the distance between 

 M3+4 and M2 on its caudal border; humeral ridge well marked; abdomen 

 elongate; propodeum except the angles, femora except their apices, 



postscutellum and most of clypeus black 



(Pseudomasaris) zonalis (Cresson). 



Middle tibia gradually widened from base to apex; cephalic margin of 

 cell R4+5 more than one-half the distance between M3+4 and M, on its 

 caudal margin; humeral ridge almost obsolete; abdomen short, ovate; 

 propodeum, except two spots behind, femora, except basal half to 

 three-quarters of posterior surfaces, postscutellum at apex, and most 

 of clypeus, saffron yellow (Pseudomasaris) coquilletti Rohwer. 



Toryna, new subgenus 



(^. Eyes deeply emarginate, the emargination obtuse, the eyes more 

 than twice as far apart above as the distance between the hind ocelli ; 

 labial palpus 2-segmented, the first niore than twice as long as the 

 second; maxillary palpus very short and conical. Antenna a little 

 longer than the head and thorax united, the scape short, globose, the 

 pedicel less than one-half its length, segm. 8 to 7 distinct, 3 to 6 linear, 

 the seventh widened, about one and one-half times as long as thick at 

 apex, segm. 8 to 12 fused to form an oval club, shaped like the inverted 

 bowl of a spoon, convex above and concave beneath, the divisio2is be- 

 tween these segments only faintly apparent. 



Anterior femur normal, its undersurface convex, the tibia some- 

 what contorted, obliquely constricted at base, as long as the tarsus, the 

 latter with a lateral fringe of rather long, silky hairs ; metatarsus as 

 long as the following segments united, the fourth segment broader than 

 long ; middle femur with irregular ridges and fossae beneath, the tibia 

 from a lateral view constricted at base and strongly expanded toward 

 the apex, the expansion beneath with a fossa which fits over the femur ; 

 tibia one-fifth longer than the tarsus, fourth segment of the latter much 

 broader than long ; posterior tibia as long as the metatarsus ; meta- 

 tarsus one and three-fifth times as long as the remaining segments 

 united, plainly curved, its apex produced on the inner side into a 

 rounded lobe extending well beyond the base of the following segment, 

 and bearing a prominent crest of stout setae; hind tarsal segments 2 

 to 4 with a prominent inner fringe of setae ; the fourth segment about 

 as long as wide ; second and third ventral segments both with tubercles ;
