 much produced above the level of the eyes, distinctly divided by notches 

 and grooves into five lobes, a median, two sub-median, and two lateral, 

 the median with the inner parts of the sub-median forming the upper, 

 the outer parts oE the sub-median and the lateral with the eyes to the 

 corneal spines on each side, the two superolateral, and the corneal spines 

 to the labrum on each side, the two infero-lateral sides of the pentagon ; 

 middle of vertex concave or convex or level according as the median lobe 

 or the sub-median lobes are the higher or all are of equal height ; eyes 

 compressed, laterally very salient, with a short simple or a bifid non-
