truncated anteriorly, with a transverse crest or carina separating it 

 from the preocellar space and connecting the frontal carina;, which are 

 prominent, nearly straight, subparallel and as far apart as they are 

 from the lateral borders of the head. Posteriorly each carina curves 

 forward medially of the eye as a distinct ridge and tenninates opposite 

 its anterior end, thus enclosing a small, shallow, elliptical scrobe .about 

 the base of the antenna. Antennas 12-jointed; scape very small, 

 about twice as long as broad; first funicular joint also very small, 

 broader than long, subglobular; second joint considerably larger but also 

 broader than long, the remaining nine joints stout, cylindrical,^ dis- 

 tinctly longer than broad, increasing somewhat in length distally, 

 terminal joint nearly as long as the two preceding joints together, with 

 tapering tip. Thorax long, narrower than the head through the eyes.

Pronotum well-de\^eloped, truncated in front; mesonotum and scutellmii 

 somewhat flattened above, the former with distinct Ma-yrian furrows, 

 the latter on each side near its posterior border with a peculiar blunt, 

 spatulate spine, slightly curved inward at the tip. Epinotum longer 

 than broad; subrectangular from above, its base horizontal and twice 

 as long as the vertical declivity into which it passes through an abrupt 

 curve, the sides of the base and of the declivity above coarsely and 

 rather irregularly marginate. Petiole with a short, stout peduncle 

 anteriorly, and a thick cuboidal node, which is a little longer than broad 

 and slightly higher in front than behind, with truncated anterior and 

 posterior and rounded dorsal and lateral surfaces . Seen in profile its ventral 

 margin is slightly bisinuate, with a small triangular tooth at the anterior 

 end of the peduncle. Postpetiole distinctly broader than the petiole 

 and .broader than long, transversely elliptical, in profile truncated 

 anteriorly, convex and rounded above, its ventral border unarmed, 

 iieari}^ straight. Gaster elongate elliptical, with straight anterior
