Long. corp. 11 lin., lat. -f lin. 



Oblong-ovate, parallel, robust, subcylindrical, deeply punctate- 

 striate, sparingly pubescent, of a dark ferrugineous colour through- 

 out. Head short, transverse, slightly elongated in front ; below the 

 base of the antennae is a plane triangular depression ; immediately 

 above the base is an obscure longitudinal line ; the eyes are some- 

 what small, situated at the base of the head, not extending so far as 

 the anterior angles of the thorax ; the surface is punctate through- 

 out, and sparingly clothed (more distinctly between the eyes) with 

 ashy-grey pubescence. Thorax quadrate, rectangular ; the anterior 

 angles depressed ; the sides are marginate ; at the base is a shallow 

 transverse depression, which extends obliquely upwards along the 

 sides to the humeral angles, and which gives a prominence to the 

 anterior medial portion of the disk ; when viewed from in front, a 

 longitudinal medial fovea is apparent, which is not extended to the 

 base ; the surface is very finely and sparingly pubescent, and granu- 

 lated. Scutellum small, triangular, impimctate. Elytra broader 

 than the thorax, parallel, robust, rounded at the apex, deeply punc- 

 tate-striate throughout ; an antemedial transverse shallow depres- 

 sion (when viewed laterally) gives an appearance of prominence to 

 the anterior angles ; the surface is very sparingly clothed through- 

 out with fine pubescence of an ashy-grey colour. Antennce robust, 

 slightly incrassated towards the apex, joints first to fifth being fer- 

 rugineous, and sixtb to eleventh fuscous. Legs : the anterior flavous, 

 the tibiae and tarsi being suffused with fuscous ; the posterior femora 

 are darkly rufo-fuscous, the tibiae and tarsi being pale rufous.
