Upper part of front strongly raised and produced, its posterior portion forming a large part of the superior surface of the head (crown); the true vertex confined to basal portion of crown, the ocelli thus on posterior disk of crown, usually remote from eyes and not visible in facial view 11 Upper part of front confined entirely to face, except sometimes for a narrow border; ocelli visible in facial view 15 11. Lateral sutures of front distinctly continued over the obtuse an- terior margin of the crown to near the position of the ocelli, as in the Cercopidae; antennae between and near the eyes; body.
