Sexual differences strongly marked. Male. Head very broad, 

 exceeds in width the widest part of the prothorax ; the antennal 

 supports very widely separated and laterally prominent ; the front 

 sloped gradually from the vertex, impressed along the middle, and 

 marked off from the clypeus by a transverse impression ; the 

 clypeus large and transverse, extended anteriorly some distance 

 in front of the base of the mandibles, with its sides oblique ; eyes 

 small, deeply and broadly emarginate ; gense long, with a crest or 

 ridge at their junction with the front and clypeus, their lower 

 front angle sharp and prominent ; mandibles long, curved, circum- 

 scribing a wide semicircular space, gradually narrowed towards 

 the apex, each bifid at the end. Antennae longer than the 

 body ; third joint longer than the fourth ; fifth to tenth succes- 

 sively and gradually shorter and narrower ; eleventh subelongate, 

 gradually narrowed at the end, sparsely setose beneath ; third joint 

 near the apex, and fourth to tenth along their whole length, fur- 

 nished with two poriferous grooves separated by a fine carina. 

 Prothorax transverse, widest across the middle and there furnished 

 on each side with a small tubercle, strongly narrowed thence in 

 straight or very feebly curved lines towards base and apex ; con- 

 stricted and transversely grooved near the base. Scutellum in the 

 form of an elongated triangle with acute apex. Elytra short, 

 moderately convex, obtusely rounded posteriorly, the shoulders 

 oblique. Femora fusiform-clavate, the hind pair extended a little 

 past the apex of the elytra ; tarsi rather short and broad, the first 

 joint only a little longer than the second, even in the hind tarsus. 

 Acetabula of front coxae very slightly, sometimes not at all, 

 angulated on the outer side, open posteriorly ; intercoxal process 

 rather broad, subvertical posteriorly, furnished with a small conical 

 tubercle in front of the angle. Acetabula of middle 00x33 extend 

 to the epimera ; mesosternum emarginate posteriorly, with a rather 

 strong conical tubercle in front of the emargination. 



Female. Head somewhat similar in structure to that of the male 

 but very much smaller, with the cheeks less prominent, the man- 

 dibles short and simple at the apex. Antennae shorter than the 

 body, with the joints from the fourth more dilated than in the 

 male, the eleventh shorter than the tenth. Legs shorter than in 

 the male, the tarsi not nearly so broad.
