5. The face without a ridge between the antennae. Humeral angles 

 sometimes subearinate ; angles of propodeum obtuse or dentate. Middle 

 femur usually flattened beneath, sometimes ridged ; the basal third of 

 the tibia, seen from in front sometimes distinctly contracted beneath. 



Type. — Pscudomasaris occidentalis Cresson (by original designa- 

 tion).

(^. Color black, the following parts yellow ochre to ochraceous 

 orange: face except at base of antennae, line between these, line in- 

 cluding the ocelli, clypeus, labrum, mandibles, line behind the eyes, 

 scape except at base, pedicel, third antennal segment except at sides, 

 antennal club except apical three-quarters beneath and posteriorly, 

 pronotuni except the collar and spot in front of tegulae, tegulae, large 

 spot below, 2 small spots on mesonotum anteriorly, most of scutellum, 

 angles of propodeum, legs except coxae, apex of first dorsal segment, 

 second abdominal segment except black area in middle above, third 

 segment except dark, basal, dorsal area, fourth and fifth segments ex- 

 cept bases, sixth dorsal except its base, sixth ventral entirely, and a 

 band before the prominences of the seventh dorsal segment. 



Emargination of the eyes, narrow, triangular, subacute at apex; 

 hind ocelli removed from the compound eyes by considerably less than 

 their diameter 's length ; front with an elevation below the anterior 

 ocellus, below this a small longitudinal tubercle, only slightly convex 

 with rather strong and separated punctures; clypeus very strongly 

 convex, the punctures irregularly confiuent, weaker toward the apex ; 

 labial palpi with two segments, the second segment little over one-half 

 as long as the first, its apical part contracted and almost discrete, 

 forming an incomplete third segment ; the segment of the maxillary 

 palpus a little longer than usual, not a mere tubercle. Segments 3 

 to 6 of antenna not at all enlarged at their apices ; the seventh slightly 

 enlarged at apex but more than twice as long as broad ; the club oval, 

 convex above and below, a very little longer than segments 6 -f ''^• 



Humeral angles slightly prominent but not at all angled; pro- 

 notuni rather closely punctate, medially impunctate ; mesonotum with 

 coarse and well separated punctures in front, becoming finer and closer 

 as they approach the middle ; posterior portion of the mesonotum flat- 

 tened but not depressed, polished, with minute and scattered punc- 

 tures; scutellum rather strongly convex, the slight anterior median 

 ridge minutely obscurely punctuate, somewhat shining ; angles of the 

 propodeum sharply dentate ; pleura coarsely punctate.
