broadly foveolate, the ventral half clothed with sparse black 

 pubescence, and not so coarsely sculptured as the dorsal half; the 

 dorsal half of the posterior face of propodeum and the dorsum of 

 the propodeum clothed with long, erect, scarlet pubescence. 



Abdomen very dark mahogany red; first tergite glabrous except 

 for a few coarse punctures at the sides and small, confluent punctures 

 at the apical margin, Avith a subapical transverse row of very long, 

 erect, black hairs, and an apical fringe of black pubescence; second 

 tergite with large, more or less confluent punctures throughout, those 

 at the basal lateral angles larger and coarser, clothed with thick, long, 

 erect and recumbent, scarlet pubescence, except the basal lateral 

 angles with sparse, black pubescence; tergites 3-5 with small, close 

 punctures, clothed with long, erect, scarlet pubescence; pygidium 

 longitudinally rugose on the basal three-fourths, granulate on the 

 apical fourth; median carina of first sternite present but not denti- 

 form ; second sternite with large, separated punctures, very sparsely 

 clothed with erect, black pubescence, and an apical fringe of black 

 pubescence, the latter with a few scarlet hairs laterally ; sternites 3-5 

 with moderate, close punctures, each sternite with an apical fringe 

 of black pubescence, the fringe with a few scarlet hairs laterally. 



Legs very dark mahogany red ; clothed with long, black hairs.

This species is very much like sackeriu (Cresson), but differs from 

 that species in the sculpture of the genae, the color of the pubescence 

 (although the yellow specimens of sackenii are practically the same 

 color as the brown ocher ones of this species), and the character of 

 the pubescence on the femora beneath. While most of tlie paratypes
