nent, anteriorly moderately converging ; front not dilated ; 

 epistoma truncate in feeble arc ; labrum moderately transverse 

 and exposed ; mandible emarginate, superior cusp acute and 

 longer than the smaller and shorter cusp ; mentum small and 

 subquadrate, gular peduncle distinct ; labial palpi small ; 

 maxillary palpi with the last joint dilated and triangular ; 

 antennae n-jointed, inserted under a distinct ridge. Eyes 

 absent. Prothorax loosely articulated with the mesosternum ; 

 prosternum not at all prominent ventrally, rather long before 

 the coxae ; propleura slightly convex and not defined from the 

 prosternum. Elytra at humeri quite rapidly retreating posteri- 

 orly so as to give a feeble sub-pedunculated appearance to the 

 body , not widely nor firmly embracing the flanks of the abdomen ; 

 epipleura narrow, scarcely inflexed, and not well defined from 

 the elytral disc, margin broadly and slightly sinuate behind 

 the sterna. Mesosternum and metasternum moderate in 

 length, the former scarcely more prominent ventrally between 

 the coxae than the anterior condylar portion. Scutellum 

 broad and triangular, not prominent nor very distinctly de- 

 fined and but feebly entering between the elytra. Epister- 

 nal pieces not distinctly defined, the metasternal episterna 

 evidently narrow with the epimera short and as long as wide. 

 Hind margins of the third and fourth abdominal segments sub- 

 coriaceous, with the third and fourth ventral sutures moder- 

 ately impressed, corresponding segments not emarginate at 

 apex. Intercoxal abdominal process broad and parabolically 

 rounded between the coxae and about a third of its width 

 wider than the mesosternal salient. Sternal sutures scarcely 

 at all evident. Anterior coxae small and rounded, rather nar- 

 rowly separated by the prosternum. Middle coxae rounded, 

 moderately widely separated and with a small but distinct 

 trochantin. Hind coxae oval, feebly narrowed externally, 

 transverse and distant. Legs moderate and simple; profe- 

 mora moderately clavate, mesofemora less so, metafemora but 

 slightly thickened externally. Tibial spurs small and distinct. 

 Tarsi obsoletely grooved beneath, and moderately slender ; 

 claws slender and simple. 



An analysis of structural characters shows that the genus
