 ceous, blackish at the base. Mesonotum closely punctured, 

 more slightly at the sides. Scutellum strongly longitu- 

 dinally punctured, narrowed considerably towards the 

 apex, the sides stoutly keeled ; the part underneath these 

 lateral keels bearing stout, distinctly separated keels, the 

 lateral keels at the apex projecting and having an oblique 

 slope. Postscutellum not defined. Median segment large, 

 flat at the base ; the apex with a slightly oblique slope ; 

 the base of the segment smooth ; the supramedian area 

 broader than long, slightly dilated towards the apex ; the 

 posterior median at the top obliquely, at the middle and 

 apex strongly, transversely striated. The spiracular area

 shining, the top finely punctured ; at the base is a distinct 

 keel, curved at the top below the tegulse and having on its 

 hinder edge below some stout striations ; the apex of the 

 mesopleurae is crenulated, and the sternum is separated 

 from the pleurae by a deep depression at the base bor- 

 dered on its lower side by a stout keel. Metapleurae, 

 except at the top towards the base, stoutly striolated, the
