above the ocellus, constricted and subobliterated below the ocellus. The

 to the middle legs, flat and rugose above ; sides perpendicularly deflexed, 

 forming distinct humeral angles ; transverse incisions distinct, the posterior 

 in front of the middle ; median carina somewhat distinct on the posterior 

 lobe, obliterated on the anterior lobes ; lateral carina? distinct, not elevated ; 

 disk of the posterior lobe elongate-tuberculate ; anterior margin truncate ; 

 the posterior extremity elongate, extending upon the second abdominal seg- 

 ment, giving the posterior lobe an elongate-ovate form ; posterior lateral mar- 

 gins quite oblique, and slightly but regularly incurved. Abdomen verv 

 large, tapering rapidly posteriorly, not carinate above. Elytra squarnose, 

 extending only to the middle of the second abdominal segment ; minutely 

 reticulated ; longitudinal veins inconspicuous ; wings minute. Posterior 

 femora shorter than the abdomen, robust, and convex on the disk ; pinna? not 

 distinctly angulated on the disk but simply curved, and somewhat bifurcated 

 above, giving the disk somewhat the appearance of being covered by imbri- 

 cated scales; upper and lower carina? hairy. Posterior tibia? curved forward 

 in the lower half, expanding below, with strong, somewhat distant, and 

 slightly incurved spines nearly to the knee, hairy, especially between the

 tips of the valves of the ovipositor and of the tibial spines black ; sternum 

 and venter yellow.
