Head scarcely longer than broad, trigonate ; front impressed 
above the encarpas with a deep fovea; encarpse thickened,

along the suture, distinctly punctured, interspaces granulose, 
faintly wrinkled on the hinder disk ; the yellow fascia, which 
is narrowly dilated on the extreme sutural margin, is slightly 
curved, its concavity looking backwards.
