above in a short, sharp carina between the antennse, and the latéral 

 arms of which are short and end in a distinct, blunt prominence; the 

 lower edge of this triangle broadly emarginate. Below this portion 

 the disk of the clypeus forms a transverse, impunctate, and highly 

 polished trough, rather flat except as it slopes upward above; in the 

 middle of the anterior part of this trough is a very slight tubercle. 

 Anterior margin of clypeus preceded by a few punctures, squarely 

 truncate; its edge slightly reflexed, terminating on each side in a 

 small tooth which projects laterad, and conunued obliquely to each 

 side in a small carina which runs towards the condyle of the mandibles. 

 Mandibles with a very strong inferior tooth; their apices bluntly 

 pointed; with an obtuse inner tooth, but not strongly widened. Scape 

 long, rather shiny; its upper surface with white hairs, but not bearing 

 distinct scopae. Second segment of flagellum subequal in length to 

 the third. Thorax moderately short; its dorsal surface uniformly 

 convex; the angles and the anterior margin of the pronotum rounded. 

 Pronotum and mesonotum closely and rather coarsely punctured; 

 the mesonotum with a médian, longitudinal, polished ridge at the 

 sides of which the parapsidal furrows, especially posteriorly, are very 

 deeply marked; between thèse and the tegulae are weakly impressed, 

 additional, longitudinal grooves. Scutellum strongly conical; its 

 summit with an oblique, slightly compressed, polished, broad ridge, 

 rounded in front and abruptly truncate at apex, the rest of the scut- 

 ellum is more closely punctured than the mesonotum. Postscutellum 

 obliquely elevated, forming part of the base of the scutellar cône, 

 weakly punctate in the middle. Mesopleurae of irregular conforma- 

 tion, there being a strong swelhng below the tegulaî and anoth^r 

 above the middle coxse. Tegulae shiny, with a few small punctures 

 around the edges and strias around the outer edge. Propodeum with 

 the sculpture of its dorsal surface obscured by pubescence, excepting 

 for a médian, longitudinal area demarcated by posteriorly converging 

 carina? and which ends in an élévation at the junction with the pos- 

 terior surface; the latter is coarsely reticulate, but the meshes rather 

 small; the upper latéral surface similarly reticulate. First tergite seen 

 from above with its sides diverging at a lesser angle than that made 

 by the Fides of the second segment at base; its width at apex much 

 less than the maximum width of the second segment; seen from the
