frontal carina approximated, not truncate behind where they unite 

 and join the short frontal furrow. Carina of cheeks very prominent, 

 forming a projecting tooth and dividing behind to form two ridges, 

 one of which runs to the anterior orbit, the other to the antennal 

 fovea. Postocular carina absent. Occipital border of head deeply 

 and subangularly excised and marginate, the margination surrounding 

 the rather acute inferoposterior corners and extending forward on 

 the sides of the gula to the level of the middle of the eyes. Antennae

 crassated towards their tips, first and second funicular joints as long 

 as broad; joints 3-9 distinctly broader than long; tenth joint as long
