 the forehead plane, not impressed, stria complete and semi- 

 circular, surface very finely punctulate; the thorax also very 

 finely punctulate, with two discal foveas separated by about 

 the width of the head, inner lateral stria complete, outer 

 dimidiate or sometimes longer ; the elytra, stria?, inner 

 humeral shortened one third at the base, dorsal 1-4 complete,

 and pygidium very finely punctulate, the first has two shallow

 but it is otherwise very similar. The thoracic foveye are 

 very peculiar, and had I only a single example I should 

 have considered them incidental.
