Antenna? nearly reaching to. the apex of the elytra • the 

 third and four or five following joints angular at their apex, 

 but not spined. Head and thorax densely rugose, the latter 

 more strongly so, with a black tubercle on each side of the 

 disk anteriorly, and two black tubercles at the side ; the 

 thorax is obliquely narrowed in front of the anterior lateral 

 tubercle, strongly constricted at the base. The elytra are 

 pale testaceous, except at the extreme base (where they are 

 tinted with brown) , shining ; each with an ovate yellowish 

 ivory spot in the middle of the base, a second rather before 

 the middle, with a brown dot joining above, and a third 

 rather longer spot some distance from the apex, this has a 

 brown dot joining it above and below ; the apex has two 

 sharp spines, of which the outer one is the stronger.
