 wider than high; ocelli large, prominent, much nearer to each other than to the eyes and situated about 

 on a line drawn through centers of eyes; inferior margins of genas at first straight and then suddenly 

 curved downward; clypeus not extending below the inferior margins of the genae but continuing the 

 rounded apical outline of the face made by the genae. Pronotum elevated in a high, pyramidal crest 

 arising from back of the metopidium with its frontal margin behind the line of the humeral angles; meto- 

 pidium sloping, triangular; median carina strongly percurrent; humeral angles large, broad, triangular, 

 blunt, extending outward beyond the eyes as far as the width of the eyes ; sides of pronotum punctate,
