Long. corp. 1-| lin., lat. 1 lin. 



Oblong- ovate, broad, robust, subparallel, fusco-ferrugineous, finely- 

 pubescent. Head short, transverse, depressed, slightly elongate ; 

 above the labrum is a transverse plane depression ; above the inser- 

 tion of the antennae is an obsolete medial carination ; eyes situated 

 at the base of the head, not extending laterally so far as the ante- 

 rior angles of the thorax ; the surface finely and thickly punctate ; 

 near the inner margin of the eyes flavo-pubescent. TJiorax trans- 

 verse (almost quadrate) ; the anterior angles subtruncate ; the sides 

 marginate, and slightly constricted at the base ; the surface thickly 

 clothed with a fine ashy pubescence. Seutellum triangular. Elytra 

 broad, robust, punctate-striate, antemedially very slightly trans- 

 versely depressed, clothed throughout with a fine ashy pubescence ; 

 postmedially are two circular obscure spots between the third and 

 the sixth striae, and two others, nearer to the base (smaller and less 

 distinct, between the first and third striae), which are formed by the 

 absence of this ashy pubescence. Antenna} filiform, slightly dilated 

 towards the apex ; joints one to five ferrugineous (the first being 

 suffused with fuscous), six to eight piceous, nine to eleven testaceous. 

 Legs : the anterior flavous ; the posterior femora rufo-ferrugineous, 

 and the tibiae rufous.
