 rowed at base ; cheeks nearly as broad as eyes ; posterior ocelli about 

 as far apart as their distance from inner margin of eyes ; pronotum 

 comparatively broad, notched in the centre, raised above the

 somewhat narrowed posteriorly, rather steeply sloped, rugose at the 

 sides and apex, with no enclosed space at base, but with a narrow 

 median longitudinal furrow, which becomes slightly broader at apex ;
