to apex, strongly convex above, smooth and shining with a few widely 
scattered small, shallow punctures emitting long, conspicuous setae, 
a few larger punctures grouped above spiracle. 
remarks : There is considerable variation in the female with regard 
to development of the propodeal carinae and in the sculpture of the 
postpetiole. These characters are not themselves correlated nor are 
they related to other possible distinguishing features. There is thus 
no basis for recognizing more than one species in the material at 
hand. 
specific name : This species is named in honor of Dr. Abraham 
Willink of the Institute Lillo of the Universidad Nacional de Tucu- 
man, Tucuman, Argentina in thanks for his kind and expert help 
during my visit to Argentina in November and December of 1964 
and in recognition of his valuable series of monographs on the neo- 
tropical Hymenoptera.

male: Color: Head, thorax, coxae, propodeum, and gaster dull 
metallic blue-green, becoming almost black on head and dorsum of 
thorax; antenna dull blackish-brown; mandible tipped with brownish- 
piceous; trochanters shining blackish-piceous, narrowly brownish on 
apices; fore-femur brown, broadly marked with pale testaceous toward 
apex; hind-femur bright pale orange, a little stained with brown at 
base and apically above; tibiae and tarsi brownish-black, fore-tibia 
broadly testaceous below; wings rather dark, with metallic reflections. 
Length of fore-wing: about 7.4 to 7.6 mm. Antenna: first flagello- 
mere about 2.4 times as long as wide apically; tyloides linear, on 
flagellomeres 9 to 17. Malar Space: about 1.2 to 1.3 times as long 
as basal width of mandible. Temples: rounded-off, scarcely receding, 
about 0.76 to 0.78 times as long as eye in dorsal view. Propodeum : 
lower and flatter in profile than in P. willink i, dorsal face more 
steeply sloping and more smoothly merging with apical face; mostly 
smooth and shining with some large adjacent or subadjacent punc- 
tures laterally and on apical Y ; with prominent long, erect setae, 
which are conspicuously sparser than in P. willinki, laterally and to- 
ward apex. First gastric segment: postpetiole moderately expanded,
