of the médian part of the front obscured by the vestiture. Ocelli in an 

 equilateral triangle, the base of which is slightly anterior to the post- 

 cular line. Eyes deeply emarginate. Antennal grooves strongly mar- 

 gined superiorly. Superior, raised portion of the clypeus ending in 

 an acute point above, between the antennas; its surface punctulate 

 and clothed with long hairs; its two arms extending downward and to 

 the sides, not very definitely limited and enclosing the upper sloping 

 portion of the transverse, depressed, smooth and polished disk; the 

 flattened sides of the clypeus towards the condyle of the mandibles 

 impunctate and polished except for a few médian, microscopic striolae; 

 the anterior margin of this discal portion truncate, with rounded 

 latéral angles and preceded by a shallow, weakly impressed, trans- 

 verse groove bearing a few hairs. Mandibles with a strong tooth on 

 the lower margin, inner margin with a tooth before the apex; their 

 upper surface with a sharp ridge which is not, however, raised into 

 a strong carina. Scape strongly contorted toward the apex and some- 

 what widened, the under surface smooth and polished. Second seg- 

 ment of flagellum as long as the third. Dorsum sculptured like the 

 vertex. Anterior margin and angles of the pronotum rounded; disk 

 of mesonotum with a médian, impunctate, polished line, on each 

 side of which are, posteriorly, deeply marked parapsidal furrows. 

 Scutellum flat, coarsely punctured, with a médian irregular, impunc- 

 tate ridge which is not raised posteriorly. Propodeum reticulate; basai 

 area obscured by vestiture; but apparently with a médian area which 

 extends tapering to the apex of the dorsal surface; latéral surface 

 reticulate. First abdominal segment as seen from the side gradually 

 and evenly widened; above without distinct differentiation between 

 anterior and posterior surfaces, merging evenly into the second; as 

 seen from above it is narrower at the apex than the greatest width 

 of the second segment from which it is slightly constricted at apex; 

 its ventral, médian carina elevated and rectangularly truncate pos- 

 teriorly. Second segment as seen from above suddenly constricted 

 before its apex, so that its sides are noticeably tuberculate; the basai, 

 médian portion of its tergite rather sparsely, its discal portion very 

 sparsely, but coarsely punctate; its sternite slightly elevated in the 

 middle at base, but not tuberculate nor carinate; the sides of its 

 sternite spatter-punctured, medially with a longitudinal, impunctate,
