fulvous pubescence; thorax as broad, or very slightly broader than 

 long; pygidium irregularly rugose; length, 9.5 mm. 



Head very dark mahogany red ; clothed throughout with long, ap- 

 pressed and erect pubescence, that of the vertex fulvous, the re- 

 mainder black ; mandibles acute at the apex, unidentate within near 

 the apex (one-fourth the total length of the mandible, from the tip) ; 

 anterior margin of clypeus distinctly bidentate medially; anterior 

 half of clypeus glabrous, impunctate ; posterior half of clypeus finely, 

 densely punctate, clothed with long, black pubescence forming the 

 dypeal fringe ; scape indistinctly punctate, clothed with coarse, black 

 hairs; first segment of flagellum twice as long as it is broad at the 

 apex, equal in length (ventrally) to segments two and three united; 

 antennal scrobes carinate above; front, vertex and genae coarsely, 

 more or less confluently punctate ; relative widths of head and thorax, 

 7.25-8.5. 



Thorax very dark mahogany red, as broad as, or very slightly 

 broader than long; dorsum clothed with long, appressed and erect, 

 fulvous pubescence, the remainder clothed with sparse, long, erect, 

 black pubescence ; dorsum coarsely, f oveately, more or less confluently 

 punctured; scutellar scale absent; propleura coarsely, contiguously 

 punctate; anterior half of mesopleura with fine, scattered punctures 

 anteriorly, moderate, scattered punctures posteriorly; posterior half 

 of mesopleura with coarse, confluent punctures throughout; meta- 

 pleura glabrous, impunctate, except for scattered, moderate punctures 

 on the ventral third, and large, contiguous punctures at the ventral 

 margin ; sides of propodeum with scattered, moderate punctures, the 

 punctures coarser and closer toward the posterior margin ; sides and 

 dorsal half of posterior face of propodeum shallowly, foveately punc- 

 tured, the disk of the ventral half depressed and moderately, in- 

 distinctly punctate. 



Abdomen dark mahoganj^ red, clothed v/ith long, appressed and 

 erect, black pubescence, except the disk of the second abdominal ter~ 

 gite clothed with long, appressed and erect, fulvous pubescence; 

 apical fringe of second tergite black ; first segment short, subsessile ; 

 the first tergite with coarse, contiguous punctures ; narrow basal mar- 

 gin of second tergite glabrous, impunctate, sides of tergite with 

 large, coarse, contiguous punctures, the disk with smaller, close punc- 

 tures; tergites 3-5 with close, moderate punctures; basal two-thirds 

 of pygidium irregularly^ rugose, the apical third granulate; median 

 carina of first sternite somewhat prominent, but not dentate, the 

 sternite closely punctured; second sternite slightly gibbose medially 

 at the base, the disk with moderate, separated punctures, the sides 

 and apical margin with coarse, contiguous punctures; sternites 3-5 

 with coarse, contiguous punctures.
